     While the disclosure is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit aspects of the disclosure to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the disclosure. 
     DESCRIPTION 
     The following description should be read with reference to the drawings wherein like reference numerals indicate like elements throughout the several views. The description and drawings show several examples which are meant to be illustrative in nature. 
     For convenience, the present disclosure may be described using relative terms including, for example, left, right, top, bottom, front, back, upper, lower, up, and down, as well as others. It is to be understood that these terms are merely used for illustrative purposes and are not meant to be limiting in any manner. 
     As shown in  FIGS. 1-15 , in one illustrative embodiment, which is not meant to be limiting, a thermostat  10  or other electronic assembly may have a first sub-assembly  14  (e.g., a thermostat body or other sub-assembly) with a housing (e.g., a first housing) and a second sub-assembly  16  (e.g., a wall plate sub-assembly or other sub-assembly) with a housing (e.g., a second housing), where the first sub-assembly  14  and/or the second sub-assembly  16  may be provided individually or in combination. In the example shown, the second sub-assembly  16  may be capable of being mounted on a wall with one or more connectors (e.g., threaded connectors or other connectors, as desired). The first sub-assembly  14  may connect or otherwise be adjustably fixed with respect to the second sub-assembly  16 . 
     Illustratively, the first sub-assembly  14  may have extensions  26  capable of engaging openings  28  of the second sub-assembly  16  in a separable manner. The extensions  26  and the openings  28  may engage one another (e.g., at a bottom of the thermostat  10 ) to create a hinge mechanism capable of supporting the first sub-assembly in an opened position and, optionally, without any further connecting features, as best shown in  FIGS. 8 and 9 . In one example, the formed hinge mechanism may have a kinematic backstop  29  and a release button or latch. Alternatively, the formed hinge mechanism with a kinematic backstop  29  may omit the button or latch and may be readily separable by lifting up on the first sub-assembly  14 , as best shown in  FIGS. 8 and 9 . 
     In the example shown, an enclosure  12  may house features of only the first sub-assembly  14 , only features of the second sub-assembly  16 , or features of the first sub-assembly  14  and features of the second sub-assembly  16 . The enclosure  12  may include various latches, extensions, openings, hinges, button, and/or other connecting features that may facilitate connecting or snap together various portions of the enclosure  12  without the need for a separate fastener (e.g., a threaded member such as screw, bolt or other fastener). Alternatively, one or more separate fasteners (e.g., a threaded fastener) may be used to connect one or more portions of the enclosure  12 . In one example, first sub-assembly  14  may have a button  36  with a latch  37 , as best shown in  FIGS. 8 and 9 , where the latch  37  may engage the second sub-assembly  16  and the button  36  may be pressed to release the connection between the latch  37  and the second sub-assembly  16 . 
     In some instances, the enclosure  12  may be formed to provide a visually thin or minimalist appearance, as best shown in  FIGS. 1-7 . For example, when the thermostat  10  is mounted to a wall or other structure, the thermostat may have one or more outer side walls that taper inward and toward the wall or other structure to which the thermostat  10  is mounted. This taper may help create the illusion that the thermostat  10  is thinner than it actually is. 
     In some instances, the enclosure  12  may include an indicator  34  that may be viewable from a first side  14   a  of the first sub-assembly  14  (e.g., where the first sub-assembly  14  has a first side  14   a  and a second side  14   b ), as best shown in  FIGS. 1-3 and 6 . In some instances, the indicator  34  may be a warning light, an indicator light indicating an alert is ready to be view, or any other type of light or indicator. In some examples, the indicator  34  may include a semi-transparent plastic material covering a light source (e.g., one or more lights such as an LED) that in some cases may be capable of changing colors. In some instances, the light may be electrically and/or mechanically connected to a first PCB or PWB  19  that is within the enclosure  12 . 
     In some cases, the enclosure  12  may provide one or more features that may capture and/or locate the first PCB or PWB  19 , a second PCB or PWB  20 , and/or other features of the first sub-assembly  14  and/or the second sub-assembly  16 . For example, one or more projections  50  may extend from the interior of the enclosure  12 , as best shown in  FIG. 10 , and engage the first PCB or PWB  19  and/or the second PCB or PWB  20 , and/or engage openings  51  in either of the first and/or second PCB or PWB  19 ,  20  to facilitate positioning the PCBs or PWBs  19 ,  20  and securing the PCB or PWBs  19 ,  20  in place within the enclosure  12 . 
     The enclosure  12  may be made from any material and by any process, as desired. In one example, the enclosure material may be injection molded with high impact polystyrene, acrylic-plexiglass, and/or any other material. 
     In some instances, the first sub-assembly  14  may include a housing  13  (e.g., a first housing) of the enclosure  12  (e.g., a plastic housing  13  having a cover  13   a  and a back  13   b  or a housing  13  made from any other material and/or with any number of separable parts, if any) and a display sub-assembly  24  (e.g., a touch screen display) that may be positionable substantially within the housing  13 . Among other features, the housing  13  may house a processor or controller, a battery compartment  70 , a battery power input, a wired power port, wired control port, a wireless interface, and/or any other suitable components. In some cases, the housing  13  may house a first printed circuit board (PCB) or first printed wiring board (PWB)  19  where the cover  13   a  may be positioned adjacent a first side  19   a  of the first PCB or PWB  19 , and the back  13   b  may be positioned adjacent a second side  19   b  of the first PCB or PWB  19 . The second sub-assembly  16  may be configured to be releasably secured to the first sub-assembly  14  adjacent to the back  13   b  of the housing  13  of the first sub-assembly  14 . 
     A wired power port may be capable of receiving power from an optional external wired power source to power the thermostat  10 . A battery power input may be capable of receiving power from an optional battery in a battery compartment to power the thermostat  10 . In some cases, the battery power input will optionally or automatically cease drawing power from the optional battery when the wired control port senses power from a wired power source. Alternatively, or in addition, the battery power input may be capable of optionally or automatically receiving power from the optional battery inserted into the battery compartment  70  when it is sensed that the wired power port is not receiving power from a wired power source. In some instances, the processor or controller may be capable of determining from which power source power is drawn and/or may be utilized to set optional, customizable, or automatic power draw settings. Illustratively, the processor or controller may be configured to operate under one or more power configurations. For example, the processor or controller may be capable of operating by receiving power form only the battery power input, receiving power from only the wired power port, or receiving power from the battery power input and the wired power port. 
     The processor or controller may be capable of generating one or more control signals configured to be sent to one or more HVAC components in communication with the thermostat  10  via a wired or wireless interface. In some cases, a wireless interface may be capable of optionally wirelessly connecting the thermostat  10  directly or indirectly to the one or more HVAC components, and may be capable of providing the control signals generated by the processor or controller to the one or more HVAC components via the wireless interface. A wired control port may be capable of optionally connecting the thermostat  10  directly or indirectly to one or more HVAC components via one or more wires, and may be capable of providing the control signals generated by the controller to the one or more HVAC components via the one or more wires. 
     The processor or controller may be configured to operate under one or more control configuration. For example, the processor or controller may be capable of controlling one or more HVAC component using only the wired control port, using only the wireless interface, or using the wired control port and the wireless interface. In some illustrative instances, the wireless interface and/or the wired control port may be optionally simultaneously or alternatively selected for communicating control signals to HVAC components in communication with the thermostat  10 . 
     The first PCB or PWB  19  may have any shape or size, as desired. In some instances, the first PCB or PWB  19  may have a portion  38  that is configured to receive a memory card connector  40 , as best shown in  FIG. 11 . The portion  38  of the first PCB or PWB  19  that is configured to receive a memory card connector  40  may have a perimeter that extends (e.g., juts out) from a main portion of the PCB or PWB  19 . In one instance, such extension of the PCB or PWB  19  may facilitate ESD protection of the board (and electronic components mounted on the board) while allowing for the thermostat  10  to receive an external memory card  41 . 
     In some instances, the second sub-assembly  16  may be a wall plate  18 , and may include a second PCB or PWB  20  with electronic components  22  (e.g., terminal blocks  33 , relays, latching relays, etc., of which only a few are illustratively labeled in the Figures) and/or other features or components. In some cases, one or more wires from a building conditioning system (e.g., a heating, ventilation, and air conditioning (HVAC) system) may connect to a terminal block  33  or other component of the second PCB or PWB  20  of the second sub-assembly  16 . 
     The wall plate  18  may facilitate securing the second PCB or PWB  20  therein in a floating manner. For example, a lateral space or gap may be formed between an edge of the second PCB or PWB  20  and the wall plate  18 . In some instances, the floating connection between the wall plate  18  and the second PCB or PWB  20  may facilitate inter-board connection (e.g., with the first PCB or PWB  19 ) during an installation procedure, such as when connecting the first sub-assembly  14  and the second sub-assembly  16  (e.g., through an electrical connection and/or mechanical connection). 
     The first PCB or PWB  19  and the second PCB or PWB  20  may structurally complement one another. For example, electronic components  22  may extend from the first PCB or PWB  19  and/or from the second PCB or PWB by varying distances toward the other PCB or PWB. Also, the electronic components  22  may arranged on each of the PCB or PWB  19 ,  20  such that the electronic components  22  that extend a relatively far distance from one of the PCB or PWB  19 ,  20  are aligned with either no electronic component of the other PCB or PWB  19 ,  20 , or are aligned with an electronic components  22  that extends a relatively short distance from the other PCB or PWB  19 ,  20 . 
     As shown in  FIGS. 10 and 11 , the first side  19   a  of the first PCB or PWB  19  may face the second PCB or PWB  20 , and the second side  19   b  may face away from the second PCB or PWB  20 . Also, the second PCB or PWB  20  may include a first side  20   a  that faces the first PCB or PWB  19 , and a second side  20   b  that faces away from the first PCB or PWB  19 , such that the first side  19   a  of the first PCB or PWB  19  is spaced from the first side  20   a  of the second PCB or PWB  20  by a spacing when the first PCB or PWB  19  is releasably engaged relative to the second PCB or PWB  20  via the first sub-assembly  14  and the second sub-assembly  16 . In some instances, one or more component (e.g., an electrical or electronic component or any other type of component, including but not limited to an inter-board connector  30 A- 30 B) may be complementarily mounted to each of the first side  19   a  of the first PCB or PWB  19  and the first side  20   a  of the second PCB or PWB  20 . In one example of complementary spacing of components, a component mounted on the first side  19   a  of the first PCB or PWB  19  may extend a first distance from the first PCB or PWB  19  toward the second PCB or PWB  20 , and a component mounted on the first side  20   a  of the second PCB or PWB  20  may extend a second distance from the second PCB or PWB  20  toward the first PCB or PWB  19  when the first sub-assembly  14  is releasably engaged with the second sub-assembly  16 . In some instances, the sum of the first distance and the second distance may be greater than a distance of the spacing between the first PCB or PWB  19  and the second PCB or PWB  20 . In some instances, the one or more components mounted to the first PCB or PWB  19  and the one or more components mounted to the second PCB or PWB  20  may be laterally offset relative to one another. In other instances, taller components on the first PCB or PWB  19  may align with or overlap shorter components on the second PCB or PWB  20  to help provide a more compact and thinner overall profile. 
     One or more of the components mounted on the PCBs or PWBs  19 ,  20  may include an inter-board connector  30 A- 30 B. As shown in the Figures, the inter-board connector  30 A may be mounted on the second PCB or PWB  20 , however, additionally or alternatively, the inter-board connector  30 B may be mounted on the first PCB or PWB  19 . To facilitate electrical communication between the first PCB or PWB  19  and the second PCB or PWB  20  via the inter-board connector(s)  30 A- 30 B, the back  13   b  of the housing  13  may include one or more apertures  23  for accommodating the inter-board connectors  30 A- 30 B. The inter-board connectors  30 A- 30 B may carry one or more signals between the first PCB or PWB  19  and the second PCB or PWB  20 . In some instances, the inter-board connectors  30 A- 30 B may be aligned and connected during connection of the first sub-assembly  14  with the second sub-assembly  16 , where such positioning may be facilitated by the hinge mechanism  32  and/or one or more other alignment features, as desired. 
     In some cases, the inter-board connector(s)  30 A- 30 B may be movable or adjustable (e.g., laterally movable or adjustable) up to a predetermined distance with respect to the first and/or second housing. Such an adjustable inter-board connector  30 A- 30 B may accommodate an amount of misalignment of the first PCB or PWB  19  and the second PCB or PWB  20  during connection of the first sub-assembly  14  with the second sub-assembly  16 . In one example, the PCB or PWB  19 ,  20  to which the inter-board connector  30 AB is mounted may be movable with respect to the housing of the sub-assembly  16  in which it is secured. In some instances, such adjustability up to a predetermined distance of the inter-board connector  30 A- 30 B and the PCB or PWB  19 ,  20  may be built into tolerances of the connection of the PCB or PWB  19 ,  20  with the respective housing, such as shown illustratively by gap  25  in  FIG. 12 . When so provided, the PCB or PWB  19 ,  20 , and thus the inter-board connector  30 A- 30 B, may be movable so as to better accommodate misalignment of the first PCB or PWB  19  and the second PCB or PWB  20  during connection of the first sub-assembly  14  with the second sub-assembly  16 , while still being able to connect the inter-board connector  30 A- 30 B. 
     The second PCB or PWB  20 , when provided, may be any shape or size capable of receiving the electronic components  22 , as desired. For example, the second PCB or PWB  20  may have a rectangular shape and a size (e.g., a surface area or other size) that is smaller than the first PCB or PWB  19 . In some instances, the second PCB or PWB  20  may be sized smaller than the first PCB or PWB  19 , where for example the first PCB or PWB  19  may extend laterally beyond one or more peripheral edges of the second PCB or PWB  20  in at least one direction to result in a non-overlapping region  27 , which may provide space to accommodate a battery assembly of the first sub-assembly  14 . 
     In one example, the non-overlapping region of the first PCB or PWB  19  may include one or more battery contacts  71  (e.g., battery terminals) to connect to one or more batteries, and/or an antenna. When batteries are positioned within the battery contacts  71 , the batteries may extend away from the first side of the first PCB or PWB  19  toward the second housing of the wall plate  18  by a distance that may be greater than the spacing between the first PCB or PWB  19  and the second PCB or PWB  20 . 
     In some instances, the non-overlapping region  27  of the first PCB or PWB  19  may include a first portion  27   a  and a second portion  27   b  (see  FIG. 14 ). The first portion  27   a  of the non-overlapping region  27  may include or carry one or more batteries within the battery contacts  71 , as described above. The second portion  27   b  may include or carry a connector (e.g., a memory card connector  40  capable of receiving a memory card  41  and/or any other connector). 
     As best shown in  FIGS. 8, 9, 11, and 13 , the battery assembly may include a battery compartment  70  that may be at least partially formed in the back  13   b  of the housing  13  and may be configured to receive one or more batteries. The battery compartment  70  may include the one or more battery contacts  71  extending therein from the first PCB or PWB  19 , and may form a cup shaped battery reservoir  72  that is capable of collecting leakage (e.g., leaked electrolytes) from one or more batteries that are inserted into the battery compartment  70 . When the first sub-assembly  14 , including the battery assembly, is connected to or secured to the second sub-assembly  16 , the second sub-assembly  16  may cover at least a portion (e.g., less than half, more than half, substantially all) of the battery assembly (e.g., the battery compartment  70 , the battery contacts  71 , and/or the battery reservoir  72 ). The wall plate  18  may include one or more recesses  21  that are configured to accommodate at least part of the one or more batteries received in the battery assembly. The battery reservoir  72  may be configured to collect leakage, if any, from one or more batteries that are received in the battery assembly, and allow it to pool therein without leaking outside the battery compartment, such as onto one or more electrical components of the first sub-assembly  14  and/or the second sub-assembly  16 . 
     In some instances, the battery contacts  71  may extend from the first PCB or PWB  19 , through the back  13   b  of the housing  13  and into the battery compartment  70 . In one illustrative example, the battery compartment  70  may be positioned within the thermostat  10  such that it may be located on or adjacent a first side  19   a  of the first PCB or PWB  19 , with a display  44  of the thermostat  10  positioned at or adjacent a second opposite side  19   b  of the first PCB or PWB  19 . 
     The battery reservoir  72  may be defined by the battery compartment  70  and may be positioned below or at least partially below the battery contacts  71  when the first sub-assembly  14  is in an upright position. The battery reservoir  72  may have one or more parts or members, and in some cases, may be formed unitarily with the enclosure  12  or may be added and/or connected to the enclosure  12  to collect leakage from the one or more batteries. In some instances, the battery reservoir  72  may be formed at least partially by a releasably securable insert  74  (see  FIG. 13 ) that may be securable to the back  13   b  of the housing  13  via an interference connection or any other type of connection. As best shown in  FIG. 15 , clips  74   a ,  74   b  formed in the back  13   b  of the housing  13  may engage corresponding engagement members of the insert  74  to releasable secure the insert  74  to the back  13   b  of the housing  13  via an interference connection. Alternatively or in addition, the battery reservoir  72  may be entirely or at least partially unitary formed with the back  13   b  of the housing  13  or other portion of the enclosure  12 , as desired. 
     The battery reservoir  72  and/or the components thereof may take on any shape configured to facilitate reception and maintenance of batteries therein. In some illustrative instances, the battery reservoir may be cup-shaped or other shape that is configured to collect leakage from one or more batteries inserted into the battery compartment  70 . 
     The battery reservoir  72  may provide space for the collection of battery leakage while preventing the leakage from affect sensitive parts and/or areas where such leakage could cause failure of the thermostat  10 . In one example, when the first sub-assembly  14  is in an upright position, the battery reservoir  72  may have a crescent, cup, or other shape that extends the length of the batteries, and in some cases, may be shaped much like a hollowed out canoe. 
     In addition to or as an alternative to the battery assembly discussed above, the first sub-assembly  14  may have a battery receptor  80  for receiving a battery  82  (e.g., a lithium ion battery or other battery). In some instances, the battery receptor  80  may be separable from the first sub-assembly  14 , as shown in  FIG. 14 , to facilitate receiving and/or removing the battery  82  from the first sub-assembly. Illustratively, the battery receptor  80  may be inserted into and/or at least partially removed from a side of the first sub-assembly  14 . When the battery receptor  80  is inserted into the first sub-assembly  14 , the battery  82  may electrically contact and/or mechanically engage battery contacts such as battery contact  84 , which may be electrically and mechanically connected to the first PCB or PWB  19 . Such electrical contact between the battery  82 , the battery contacts  84 , and the first PCB or PWB  19  may facilitate powering one or more features of the thermostat  10 . 
     The first sub-assembly  14  may be powered with one or more received or connected batteries or other power sources (e.g., a first power source). In some cases, the second sub-assembly  16  may be powered with a wired connection to the power of a building (e.g., a second power source). In some instances, the first sub-assembly  14  may be powered by the same power source powering the second sub-assembly  16  through electronic connection(s) between the first sub-assembly  14  and the second sub-assembly  16  (e.g., the first power source and the second power source may be the same power source). 
     The first sub-assembly  14  and the second sub-assembly  16  may include electronic components  22 , which in some cases, may be sensitive to electrostatic discharges (ESDs). The first PCB or PWB  19  of the first sub-assembly  14  may be protected from ESDs by the enclosure  12  and/or through conductors in or about the display  44  and/or touch screen  46 , as discussed further below. The second PCB or PWB  20  of the second sub-assembly  16  may be protected from ESDs in a similar manner to the first PCB or PWB  19  and/or configured such that it is substantially insensitive to ESDs due to its remote positioning or location within the enclosure  12  with respect to portions of the thermostat  10  with which users typically interact. In some cases, the second PCB or PWB  20  includes electrical components that are not susceptible, or far less susceptible, to damage caused by ESD, such as terminal blocks, relays, etc. 
     Illustratively, the first PCB or PWB  19  may be positioned adjacent the back side  24   b  of a display sub-assembly  24  (e.g., adjacent a reflective layer  45 , e.g. reflective foil or other reflective layer). The display sub-assembly  24  (e.g., a touch screen display) of the first sub-assembly  14  may have a front side (e.g., a viewing side)  24   a  and a back side (e.g., a non-viewing side)  24   b , as shown in  FIG. 16 , and conductive trace(s)  56  (further discussed below) on the front side  24   a  of the display sub-assembly  24  may be in electrical connection with one or more tails  64  (e.g., a flexible electrical connector or any other type of connector) that may mechanically and/or electrically connect to the first PCB or PWB  19  (and/or the second PCB or PWB  20 ) to provide an electrical path from the conductive trace(s)  56  to a ground plane or other grounding feature of the PCB or PWB  19 ,  20 . In some instances, the conductive trace(s)  56  may be configured to collect ESD entering between the front side  24   a  of the display sub-assembly  24  and the housing  13 , and to deliver the collected ESD to the grounding plane or other grounding feature of the PCB or PWB  19  via the tail  64  or other electrical connector. 
     With reference to  FIG. 16 , the display sub-assembly  24  may include, among other features, a backlight system  42  (e.g., including a backlight guide plate  43  for providing a back-light to the display  44  and a reflective layer  45 ), a display  44  (e.g., a liquid crystal display (LCD), a light emitting diode (LED) display, or other display), a touch screen  46  (e.g., an indium tin oxide (ITO) touch screen or other type of touch screen), and/or a frame  58  having connectors  48  for aligning and/or connecting features of the display sub-assembly  24  and/or mechanically connecting, releasably connecting, and/or removably fixing the display sub-assembly  24  to the first PCB or PWB  19 . Additionally, or alternatively, the frame  58  may include one or more protrusions capable of mating with concave features  54  of the backlight guide plate  43 . 
     In instances where the display sub-assembly  24  may include a touch screen  46 , a display  44 , a frame  58 , a backlight guide plate  43 , and a reflective layer  45 , the front side  24   a  may be formed at least partially by the touch screen  46  and the back side  24   b  may be formed at least partially by the reflective layer  45 . Alternatively or in addition, one or more of the features of the display sub-assembly  24  discussed herein or other features added to the display sub-assembly  24  may form the front side  24   a  and/or the back side  24   b  thereof, as desired. 
     Illustratively, the frame  58  may be a plastic frame or other type of frame. With reference to  FIGS. 16-20 , the frame  58  may include a front side  58   a , a back side  58   b , and side walls (e.g., top side wall  58   c , bottom side wall  58   d , and lateral side walls  58   e ) that may extend from the front side  58   a  to the back side  58   b  of the frame  58  and form a space  59  therewithin, as best shown in  FIGS. 17 and 18 . When positioned in the first sub assembly  14 , the front side  58   a  of the frame  58  may face away from the first PCB or PWB  19  and the back side  58   b  of the frame  58  may face toward the first PCB or PWB  19 . 
     One or more of the side walls of the frame  58  may include one or more reflective features  63 , where the reflective features  63  may be shaped to reflect and/or distribute incident light across at least part of the of the backlight guide plate  43 , the display  44 , and/or the touch screen  46 . As best shown in  FIGS. 19 and 20 , the top side wall  58   c  of the frame  58  may include a plurality of reflective features  63 . In some cases, the reflective features  63 , to the extent there are two or more reflective features on the frame  58 , may be substantially equally, equally, or irregularly spaced across one or more sides of the display  44  and/or touch screen  46  when the display  44  and/or the touch screen  46  are positioned within the frame  58  to substantially equally spread light across the display and/or focus light on one or more particular locations, as desired. 
     The reflective features  63  may have any shape and/or may take on any configuration with respect to the frame  58 . For example, the reflective features  63  may be formed integrally with the frame  58  or may be separate features connected to the frame  58 . The reflective features  63  may have a shape that directs reflected light in a particular manner. In one example, the reflective features  63  may be at least partially cone-shaped and/or may be convex from a back side  58   b  perspective to spread reflected light about one or more of the touch screen  46 , the display  44 , and/or the backlight guide plate  43 . 
     The backlight guide plate  43  may have a front side  43   a  and a back side  43   b , as shown in  FIGS. 21 and 22 . In some cases, back side  43   b  of the backlight guide plate  43  may be affixed to the reflective layer  45  with adhesive and/or through other mechanisms. 
     One or more recesses of the backlight guide plate  43  may correspond or be in registration with one of the one or more reflective features  63  of the frame  58 . In some cases, the one or more recesses may have a shape that is configured to mate with a corresponding reflective feature  63  of the frame  58  such that light passing through the one or more recesses may be reflected and spread out by the reflective features  63  of the frame  58 . 
     In some instances, the backlight guide plate  43  may allow light from one or more light sources  52  (e.g., light emitting diodes (LEDs), or other light sources connected to the first PCB or PWB  19  or other light features) to pass through one or more holes or openings  68  in the reflective layer  45 , where the holes or openings  68  may be in registration with the one or more recesses of the backlight guide plate  43 , so as to allow light from the one or more light sources  52  to reach the one or more recesses or concave features  54  of the backlight guide plate  43 . Such light from light sources  52  may be in registration with corresponding one or more protrusions  53  on the back side  43   b  of the backlight guide plate  43  and/or one or more recesses (e.g., at least partially concave features  54 ) on the front side  43   a  of the backlight guide plate  43  to focus light on optimized portions of reflective surfaces of the frame  58 , backlight guide plate  43 , and/or reflective layer  45 . Illustratively, the configuration of the backlight guide plate  43  in communication with light from the light sources  52  may provide light to reflective features  63  of the frame  58  and/or incident light to one or more recesses of the backlight guide plate  43  from the corresponding reflective features  63  in order to distribute the incident light across the backlight guide plate  43 , the display  44 , and/or the touch screen  46 . In some cases, the light is distributed across the display such that the display appears to have an even brightness across the display. 
     Illustratively, the display  44 , the backlight guide plate  43 , and/or the touch screen  46  may be positioned at least partially within the frame  58 . In one example, the display  44 , the backlight guide plate  43 , and/or the touch screen  46  may be at least partially positioned within the space  59  defined by the frame  58 . In some cases, one or more connectors  48 , as best shown in  FIGS. 16-20 , of the frame  58  (e.g., back stop features adjacent the back side  58   b  of the frame  58  or front stop features adjacent the front side  58   a  of the frame  58 ) may stop the display  44 , the backlight guide plate  43 , and/or the touch screen  46  from sliding out of the back side  58   b  and/or the front side  58   a  of the frame  58 . 
     In some cases, when the display sub-assembly  24  is positioned within the first sub-assembly  14 , the backlight guide plate  43  may be positioned at least partially between the display  44  and the first PCB or PWB  19 . In one illustrative example of when the display sub-assembly  24  may be positioned within the first sub-assembly  14 , some of the features thereof may be positioned in the following order (e.g., from front to back): the touch screen  46  (e.g., a touch screen module  46 ), the display  44  (e.g., a display module), the backlight guide plate  43 , and the reflective layer  45 , all secured relative to the frame  58 . The frame  58  may then secure the display sub-assembly  24  to the first PCB or PWB  19 . In some cases, one or more connectors  48  of the frame  58  (e.g., one or more first interference tabs  48   a , as best shown in  FIGS. 16, 19, and 18 , on the front side  58   a  and/or the back side  58   b  of the frame) may engage the first PCB or PWB  19  to releasably secure the display sub-assembly  24  to the first PCB or PWB  19 . The one or more connectors  48  may releasably engage the first PCB or PWB  19  through any type of connection including an interference connection where the connectors  48  extend through an opening or hole in the first PCB or PWB  19  to make a releasable connection and/or through any other type of suitable connection. 
     In some instances, the first sub-assembly  14  may be assembled according to an illustrative method. In one example method, a display  44 , a touch screen  46 , and/or a backlight guide plate  43  may be connected to the frame  58  with an interference connection or any other type of connection using one or more connectors  48  (e.g., interfering tabs  48   b  or other connectors on the back side  58   b  of the frame  58 ). In some cases, an interference connection may be a snap connection. When in the frame  58 , the backlight guide plate  43  may be positioned behind (e.g., toward the back side  58   b  of the frame  58 ) the display  44 . Illustratively, the method may further include connecting the frame to the first PCB or PWB  19  using an interference connection with one or more connectors (e.g., interfering tabs  48   a  or any other connectors), such that the backlight guide plate  43  is adjacent to the first PCB or PWB  19 , and such that one or more of the reflective features  63  of the frame may align with a corresponding light source  52  on the first PCB or PWB  19 . 
     The touch screen  46  and/or the display  44  of the display sub-assembly  24  may be secured within the enclosure  12  (e.g., within housing  13 ), as shown for example in  FIG. 11 , such that an ESD may have a path to a ground pad or grounding feature of the first PCB or PWB  19 , such that the ESD does not negatively affect (e.g. damage) the display  44  or other components. In some cases, a conductive trace  56  along, adjacent, or parallel to a perimeter of a touch screen  46  of the display sub-assembly  24  may provide a path for the ESD from the touch screen  46  or other feature to a grounding feature. Illustratively, the conductive trace  56  may extend adjacent or along and spaced from a perimeter of the aperture  15  in the housing that exposes at least part of the front side  24   a  of the display sub-assembly  24  for viewing by a user. In one example, the conductive trace  56  may be positioned on the first side  24   a  of the display sub-assembly  24  between the first side  24   a  and the housing  13  (e.g., the cover  13   a  of the housing  13 ). 
     In some cases, the touch screen  46  may include a conductive trace  56  at, around, adjacent to, spaced from, and/or parallel to a perimeter of the touch screen  46 , as best shown in  FIGS. 23-28 . The conductive trace  56  may form a complete loop (e.g., a closed loop) or may include one or more gaps therein so as to not form a closed loop. In an illustrative example, the conductive trace  56  may form a closed loop or non-closed loop and may be disposed on or adjacent the front side  24   a  of the display sub-assembly  24 , where the conductive trace  56  may be disposed at, around, adjacent to, inward from, and/or parallel to the perimeter of the touch screen  46  forming the first side of the display sub-assembly  24 . 
     In some instances, no adhesive or glue is used between the conductive trace(s)  56  and an edge of the touch screen  46  to facilitate creating an electrical path that ESD will follow. In  FIG. 23 , the conductive trace  56  is added on top of the touch screen  46 , where new wires or traces  65  on a tail  64  connect the conductive trace  56  to a ground plane or ground feature on the first PCB or PWB  19 . Alternatively, or in addition, the conductive trace  56  may be added to the display sub-assembly in any other manner. As shown in  FIG. 24 , the conductive trace  56  is connected to one of the existing wires on the tail  64 . In some illustrative cases, the conductive trace(s)  56  may be spaced inward from an outer edge of the touch screen  46  of the display sub-assembly  24 , as shown. 
     The conductive trace(s)  56  may be implemented in one or more of several different manners to effectively provide a path for the ESD to a grounding feature of or on the PCB or PWB  19 ,  20 . For example, to provide a path for an ESD to a grounding feature of or on the PCB or PWB  19 ,  20 , the conductive trace(s)  56  may extend to an edge of the display  44  (see  FIG. 25 ), strips  60  of a conductive material may be applied to the touch screen  46  that are, or are electrically connected to, the conductive traces  56  and extend to an edge of the touch screen  46  (e.g., thin strips that may be spaced approximately 0.2 inches apart and have a width of 0.02 inches, or other strips configured in any manner as desired) (e.g. see  FIG. 26 ), openings or holes  61  may be placed in the conductive trace (e.g., holes spaced approximately 0.1 inches, 0.2 inches, 0.3 inches, or any other distance apart and having a diameter of approximate 0.01 inches, 0.02 inches, 0.03 inches, 0.04 inches, 0.05 inches, or any other diameter) (e.g. see  FIG. 27 ), one or more portions  57  (represented by the hashed lines in  FIG. 28 ) of a foil layer  62  of the touch screen  46  may be removed from the edge of the touch screen  46  to an outer edge of the conductive trace(s)  56  (e.g., the foil layer  62  may be cut and removed from the touch screen  46 ) (see  FIG. 28 ), and/or any other configuration may be utilized to use the conductive traces  56  and the tail(s)  64  connected thereto to provide an electrical path to a ground feature of one or more of the first PCB or PWB  19  and the second PCB or PWB  20 . 
     As shown in the example of  FIG. 26 , the conductive trace  56  may have a first portion  56   a  and a second portion  56   b , where the first portion  56   a  may extend substantially or entirely around the front side  24   a  of the display sub-assembly  24  (e.g., at or spaced from the outer edge or perimeter of the display sub-assembly  24 ). The second portion  56   b  of the conductive trace  56  may include a plurality of strips  60  spaced from one another and extending from the first portion  56   a  of the conductive trace  56  toward and/or to the outer edge or perimeter of the display sub-assembly  24  (e.g., the outer edge or perimeter of the touch screen  46  or other feature of the display sub-assembly  24 ). 
     In an illustrative method of forming an electrical ESD path between the display sub-assembly  24  and the first PCB or PWB  19 , a conductive trace  56  may be provided on a front side  24   a  of the display sub-assembly  24  (e.g., the touch screen  46 ) adjacent a perimeter of the display sub-assembly  24 . The first PCB or PWB  19  may be positioned adjacent the back side  24   b  of the display sub-assembly  24  and the conductive trace  56  may be electrically connected to a grounding feature of the first PCB or PWB  19  via an electrical connector (e.g., at tail  64 ). 
     In one illustrative instance, the method may include mechanically connecting and/or removably fixing the display sub-assembly  24  to the first PCB or PWB  19 . In one example, the touch screen  46 , the display  44 , the reflective layer  45 , and the backlight guide plate  43  may be removably fixed within the frame  58  via connectors  48  and/or other connectors. The display sub-assembly  24  and the frame  58  may then be removably fixed to the first PCB or PWB  19  via connectors  48 , tail  64 , and/or other connectors to form a connection and an electrical ESD path between the display sub-assembly  24  and the first PCB or PWB  19 . 
     The thermostat  10  may be configured to be used with virtually all heating and cooling systems for both residential and commercial applications. Additionally, or alternatively, the thermostat  10  may be capable of working with one or more accessories (e.g., RedLINK™ accessories or any other accessory), which may allow contractors to reduce inventory costs and/or realize other business advantages. In some instances, the thermostat  10  may be wired directly to, wired indirectly to, and/or wirelessly connected to the accessories and/or power sources. 
     It is contemplated that the thermostat  10  may be powered at least in part by using one or more batteries (e.g., lithium ion batteries, AA batteries, AAA batteries, etc.), alternating current (AC), and/or direct current (DC). Although the thermostat  10  may be battery powered, it may additionally, or alternatively, be wired for power, as referred to above. In one example, the thermostat  10  may have a direct or indirect wired or wireless connection to HVAC equipment in a non-zoned HVAC system and can be powered with two (2) wires (e.g., a power or hot wire and a common wire) or by battery only. In another example, the thermostat  10  may have a direct or indirect wired or wireless connection to HVAC equipment in a zoned HVAC system and can be powered with two (2) wires (e.g., a power or hot wire and a common wire) or by battery only. In a further example, the thermostat  10  may work with an equipment interface module (EMI) where one or more pieces of HVAC equipment and/or accessories may have a wired and/or wireless connection to the EIM, while the thermostat  10  is powered with two wires (e.g., a power or hot wire and a common wire) or by battery only (e.g., for a completely wireless thermostat or for other reasons). In a further example, the thermostat  10  may work with a TrueZONE™ wireless adapter or other wireless adaptor where one or more pieces of HVAC equipment and/or accessories may have a wired or wireless connection to a TrueZONE™ panel or other zone panel such that the thermostat may control a zone panel via a wireless adapter, while the thermostat  10  may be powered with two (2) wires (e.g., a power or hot wire and a common wire) or by battery only (e.g., for a completely wireless thermostat or for other reasons). In some instances, the processor or controller of the thermostat  10  may be programmable to send control signals for HVAC components through the EIM, the wireless adapter, the zone panel and/or directly or otherwise indirectly to one or more of the HVAC components. 
     It is contemplated that latching relays may be used to provide control signals from the thermostat  10  and to an HVAC system or the like. Due to their relatively low power consumption, latching relays may be particularly useful when the thermostat  10  is battery powered. Latching relays, however, remain in their last state (latched state) until power is applied to switch the state. Thus, without proper control, the latching relays will tend to stay in their previous latched state when battery (or other) power is disconnected, and/or when becoming disconnected from a controlling microcontroller. This can cause an HVAC system to remain in a non-desirable state if either of these conditions occurs. 
     As detailed above, the second sub-assembly  16  may include a second PCB or PWB  20  with electronic components  22  (e.g., terminal blocks  33 , relays, latching relays, etc., of which only a few are illustratively labeled in the Figures) and/or other features or components. In some cases, one or more wires from a building conditioning system (e.g., a heating, ventilation, and air conditioning (HVAC) system) may connect to the terminal block  33  or other component of the second PCB or PWB  20  of the second sub-assembly  16 . A microcontroller of the first PCB or PWB  19  may generate control signals to control the state of one or more latching relays on the second PCB or PWB  20 . The one or more latching relays may then provide a corresponding control signal to the HVAC system via wires connected to the terminal blocks  33 . If power is disconnected, and/or if the first sub-assembly  14  is separated from the second sub-assembly  16 , the latching relays will remain in their previous latched state. This can be undesirable. For example, if the previous latched state corresponds to a furnace “on” state, the furnace will remain “on” until power is restored, and/or until the first sub-assembly  14  is reconnected to the second sub-assembly  16 , regardless of the temperature in the building. This can waste energy, create uncomfortable conditions, and in some cases, can cause damage. 
     As seen in  FIG. 29 , latching relays may be connected to a microprocessor or microcontroller  69  of a thermostat  10 , such that a position (e.g., an opened position or a closed position or other position) of the latching relays may be controlled by the microprocessor or microcontroller  69 . At times (e.g., when dismounting a portion of the thermostat), it may be desirable to separate the microprocessor portion (first portion  76 ) of the thermostat  10  from the other portion (e.g., second portion  78 ) that includes the latching relays. As noted above, this can cause the latching relays to be left in an undesirable or improper position. 
     In some instances, the microcontroller  69  and/or other processors of the first portion  76  of the thermostat  10 , which may or may not include ESD sensitive components, may be located on the first PWB or PCB  19  having a first set of circuitry thereon to which the microcontroller  69  may be connected. The second portion  78  of the thermostat  10  may include the second PWB or PCB  20  secured relative to a second housing  17  of the second sub-assembly  16 , where the second portion  78  of the thermostat  10  may be releasably securable to the first portion  76  of the thermostat  10 . The second PWB or PCB  20  may include a second set of circuitry (e.g., circuitry that may or may not include ESD sensitive components, but does include at least one or more relays, one or more capacitors, and/or one or more terminal blocks  33 ) capable of being powered by a power source V DD  (e.g., wired power, batteries, etc.), and configured to receive one or more control signals from the first PWB or PCB  19  when the second portion  78  is releasably engaged with the first portion  76 . The second PWB or PCB  20  may also provide one or more corresponding control signals to the one or more output terminals of the second portion  78  for control of one or more HVAC component in communication with the thermostat  10 . In some cases, the circuitry of the second PWB or PCB  20  may be configured to set one or more output terminals of the second portion  78  to a predetermined state when the first portion  76  is released and/or at least partially disengaged from the second portion  78  (e.g., disengage electrical communication from the first PWB or PCB  19  to the second PWB or PCB  20 ). In one illustrative example, the circuitry of the second PWB or PCB  20  will automatically set the output terminals of the second portion  78  to a predetermined state when the first sub-assembly  14  ceases electrical communication with (e.g., is released and/or at least partially disengaged from) the second sub-assembly  16 . 
     It is contemplated that latching relays  79 , which may be located on the second PCB or PWB  20  of the second sub-assembly  16 , may be properly configured (e.g., configured to set the output terminals to the predetermined state) when separated from a microprocessor or microcontroller  69  or the like (e.g., when the first sub-assembly  14  is separated from the second sub-assembly  16 ). For example, when the first portion  76  and the second portion  78  are engaged (e.g., in electrical communication), the configuration of the latching relays  79  may be controlled by the microcontroller  69 , and when the first portion  76  and the second portion  78  become disengaged, the configuration of the latching relays  79  may be set by circuitry on the second portion  78 . 
     In one example of utilizing the second set of circuitry on the second portion  78  to control the position of the latching relays  79  when the first sub-assembly  14  (e.g., first portion  76 ) becomes disengaged from the second sub-assembly  16  (e.g., second portion  78 ) (e.g., when the first sub-assembly  14  may be electrically disengaged from the second sub-assembly  16 ), pre-set logic levels on a control bus or on appropriate terminals may position the one or more latching relays  79  into a configuration that provides one or more corresponding control signals to the one or more output terminals of the second portion  78 . In some instances, this may be accomplished through the use of one or more pull-down resistors  85  and/or one or more pull-up resistors  77  of the second set of circuitry on the second PWB or PCB  20 . In an illustrative example, the approach used to properly position the latching relays  79  when the first portion  76  is disengaged from the second portion  78  (e.g., position the latching relays  79  so as to turn off connected external devices or position the latching relays  79  in any other predetermined manner) may be preordained for single-coil relays driven by an coil  75 . In some examples, the system may include two pull-down resistors  85  and one pull-up resistor  77 , or other configurations of resistors and/or electrical components capable of positioning the latching relays in a predetermined position so as to turn off connected external devices when the first portion  76  is at least partially electrically disconnected from the second portion  78 . 
     When the first portion  76  of the thermostat  10 , which includes the microcontroller  69  and/or other control circuit, is separated (e.g., at least partially electrically separated) from the second portion  78  of the thermostat  10  that includes the latching relays  79 , the logic levels on a control bus  73  or other terminals may no longer be set by the microcontroller  69  as they would be when the first portion  76  of the thermostat  10  is in electrical communication with the second portion  78  of the thermostat  10 . With the use of appropriate pull-down  85  and/or pull-up resistors  77  (e.g., one or more pull-down resistors  85  and one or more pull-up resistors  77 ), the logic levels may be automatically controlled by the pull-down resistor(s)  85  and/or the pull-up resistor(s)  77  in the absence of the control signals from the microcontroller  69 . As a result, once separated, the current through the relay coils of the latching relays  79  may automatically flow according to predetermined logic levels in an appropriate direction to set the state of the latching relays  79  such that all of the external devices (e.g. external device  83 ) are switched off. The particular state (off/on) for any particularly relay may be programmed by choosing an appropriate pull-up or pull-down resistor configuration. In some instances, the configuration utilizing pull-down resistors and pull-up resistor(s) may allow for the elimination of an auxiliary driving circuit, such as a microcontroller, a logic array, etc. 
     Inputs to a first part (e.g., a first terminal) and/or a second part (e.g., a second terminal) of the coils  75  may be operatively coupled to corresponding one or more control signals from the first set of circuitry of the first portion  76  of the thermostat  10  (e.g., from the microcontroller  69  of the first portion  76 ) when the first portion  76  and the second portion  78  are engaged (e.g., are electrically communicating). Inputs to the first terminal of the coils  75  may be pulled up by the pull-down resistors  85  through an operative coupling (e.g. inverter) therewith to VDD when the first portion  76  of the thermostat  10  is electrically disengaged from the second portion  78  of the thermostat  10 . Inputs to the second terminal of the coils  75  may be pulled down by a pull-up resistor  77  and a power supply V dd  through an operative coupling (e.g. inverter) therewith when the first portion  76  of the thermostat  10  is electrically disengaged from the second portion  78  of the thermostat  10 . Thus, when the first portion  76  of the thermostat  10 , which includes a microcontroller  69  or other controller, is electrically separated from second portion  78  of the thermostat  10  (e.g., electrically separated), the logic levels at the control bus  73  of the second portion  78  of the thermostat  10  may be automatically defined by the pull-down resistors  85 , and the pull-up resistor  77  through the operative couplings (e.g. inverters). As a result, current may flow in the same direction through all of the rely coils  75 , forcing all latching relays  79  into the same (e.g. closed) state. When the first portion  76  of the thermostat  10  having the microcontroller  69  is reconnected to the second portion  78  of the thermostat  10 , the microcontroller  69  (or other circuit) provides a common signal for all of the latching relays  79  to common pin  81  to over-drive the pull-up resistor  77 , and the control bus  73  may over-drive the pull-down resistors  85  to pull the relay control terminals to their desired controlled state. 
     In some cases, a capacitor or other power storage device  91  may be used to provide power to the second portion  78  of the thermostat  10  for a relatively short duration (e.g. less than 1 hour, less than 10 minutes, less than 1 minute, less than 1 second, etc). During this relatively short duration, the latching relays  79  may be set to a state that turns off all external devices  83 . Once the latching relays  79  are latched into an appropriate state, power from the power storage device  91  may no longer be needed. The power storage device  91  may be a capacitor, battery or any other power storage device, as desired. 
     As can be seen, this circuit arrangement on second portion  78  of the thermostat  10  may allow for a simple, reliable, and low cost solution to controlling the state of the relays when the first portion  76  of the thermostat  10  having a microcontroller  69  or other controller is separated from the second portion  78  of the thermostat  10  that includes latching relays. 
       FIG. 30  is an illustrative method. In method  300 , the first sub-assembly  14  may be separated (e.g., electrically separated) from the second sub-assembly  16 , as shown at  302 . As discussed above, the second sub-assembly  16  may include one or more output terminals connected to one or more external devices (e.g., a furnace, an air conditioning unit, a humidifier, a dehumidifier, etc.). Once the second sub-assembly  16  is electrically separated from the first sub-assembly  14 , one or more output terminals of the second sub-assembly  16  may be automatically set to a predetermined state, as shown at  304 . In one example, the output terminals of the second sub-assembly  16  may be automatically set to a predetermined state (e.g., such that connected external devices are turned off) by automatically setting one or more latching relays  79  of the second sub-assembly  16  to the predetermined state, where the latching relays  79  are otherwise controlled with control signals from the first sub-assembly  14  when the first sub-assembly  14  and the second sub-assembly  16  are releasably engaged or otherwise in electrical communication with each other. The first sub-assembly  14  and the second sub-assembly  16  may be reengaged  306  such that one or more control signals from first sub-assembly  14  may be provided  308  to the second sub-assembly  16 . The one or more control signals may cause the second sub-assembly  16  to provide one or more control signals to one or more external devices (e.g., HVAC components or other components) via the output terminals of the second sub-assembly  16 . 
     In some cases, the second side  20   b  of the second PCB or PWB  20  may include one or more test pads. In one illustrative example, the test pads of the second side  20   b  of the second PCB or PWB  20  may be connected and are suitable for performing functional tests of the microcontroller  69  and/or other circuitry of the first PCB or PWB  19 , and/or circuitry of the second PCB or PWB  20 , when the first sub-assembly  14  is releasably engaged with the second sub-assembly  16 . 
     The display sub-assembly  24  may create an interface display  100  on the display  44 , which a user may interact with in any manner, including, but not limited to, interacting with the interface display  100  through touching a screen, buttons adjacent to or on the interface display  100 , a remote device, and/or though some other interaction mechanisms. In some instances, the interface display  100  may be provided by a display  44  that has a 2-dimensional array of pixels that covers the full display area of the display  44 . In some instances, the interface display  100  may be provided by a display  44  that is a segmented display, which includes a plurality of predefined segments that can be switched on and off to give the appearance of desired characters, icons or other graphical features. In a segmented display, the predefined segments are not arranged in a full 2-dimensional array of pixels that covers the full display area of the display  44 . Rather, at least some of the predefined segments are elongated, define a symbol or icon, or otherwise do not fall into a simple 2-dimensional array of pixels. It is contemplated that the display  44  may be any suitable display panel using any suitable display panel technology including, for example, Eidophor, Electroluminescent display (ELD), Electronic paper (E Ink, Gyricon), Light emitting diode display (LED), Cathode ray tube (CRT) (Monoscope), Liquid-crystal display (LCD) (TFT, LED, Blue Phase, IPS), Plasma display panel (PDP) (ALiS), Digital Light Processing (DLP), Liquid crystal on silicon (LCoS), Organic light-emitting diode (OLED) (AMOLED), Organic light-emitting transistor (OLET), Surface-conduction electron-emitter display (SED), Field emission display (FED), Laser TV (Quantum dot, Liquid crystal), MEMS display (IMoD, TMOS, DMS), Quantum dot display (QD-LED), Ferro liquid display (FLD), Thick-film dielectric electroluminescent technology (TDEL), Telescopic pixel display (TPD), Laser Phosphor Display (LPD). 
     In some instances, the display  44  may be a segmented display that has predefined segments that: (1) define a 2-dimensional array of pixels in a first region or area  104  of the display  44 ; and (2) define segments of segmented characters, symbols or icons, or otherwise do not fall into a simple 2-dimensional array of pixels in a second region or area  102  of the display  44 . For simplicity, the first region or area  104  may sometimes be referred to as a dot matrix display area, and the second region or area  102  may be referred to as a fixed segment display area, even though in some cases the first region or area  104  may be formed from an array of fixed segments that are configured as a 2-dimensional array of fixed segment pixels. The first region or area  104  may function as a message center that can be used to display text based messages, animations, and/or other information. In some cases, the first region or area  104  may be configured to only display two (2) lines of text, but this is just one example. In some cases, the second region or area  102  may encompass the remainder of the display  44  that is not part of the first region or area  04 . In some cases, the display  44  may be an LCD display panel, where each of the plurality of predefined segments in both the first region or area  104  and the second region or area  102  are each layed out on a substrate and independently controllable by the processor or controller of the first sub-assembly  14 . Such an LCD panel may consume relatively low power (e.g. suitable for battery powered devices), and may be selectively backlit by the backlight system  42  of the display sub-assembly  24 . 
     The one or more areas (e.g., the second area  102 , the first area  104 , and/or other areas) may be controllable with software, firmware, and/or other computer executable instructions stored on a non-transitory computer readable medium of the thermostat  10  or other device that is capable of communicating with the thermostat  10 . In some instances, the thermostat  10  may include memory and/or a processor that is configured to save, record, and/or operate the software, firmware, or other computer executable instructions. 
     For purposes of this disclosure, where the interface display  100  is described as having first, second, and so on portions, the numerical indicators (e.g., first, second, third, etc.) are meant for explanatory purposes only and are not meant to be limiting unless otherwise indicated. The numerical indicators may are used for clarity purposes to distinguish between one feature relative to another and the numerical indicators may be switched. 
     In some cases, the message center (e.g., the first area  104  with a two (2) line dot matrix area) may be capable of displaying up to three full lines of text (e.g., three full lines of text or graphics, two full separate lines of text or graphics and up to two half or partial lines of text or graphics, two partial lines of text or graphics with one or more full lines of texts or graphics, etc.). The full and/or partial lines of text or graphics may be full or partial lines in the vertical and/or horizontal directions. In one example, the first area  104  may simultaneously display in a vertical direction an integer number of options (e.g., on a full line of text or graphics) plus a fraction of an option (e.g., on a partial line of text or graphics, on about a half line of text or graphics, etc.). In a further example, the first area  104  of the interface display  100  may simultaneously display in a vertical direction two options on separate full lines of text plus a fraction of a third option on a partial line of text. The options discussed herein may include, but are not limited to, lists of options, selectable options, installer setup options, sensor control options, program scheduling options, programmable options, menu list items or options, questions or queries, informative messages, directions, alerts, warnings, logs, other options capable of being displayed on a message center, and/or any combinations thereof. Such displayable options may be used together or separate and/or may viewed or obtained by selection of another option. 
     In some cases, programmable options may be used to set settings of the thermostat  10  that may be used for controlling subsequent operation and/or functionality of the HVAC controller. As such, selection of the options in the first area  104  of the interface display  100  may allow a user to set or change a programmable option that may modify a subsequent operation and/or functionality of the thermostat  10 . Illustratively, subsequent operation and/or functionality of the HVAC controller may include, among other features, where temperature and/or humidity is sensed, how temperature and/or humidity is sensed, a schedule for the HVAC components of the HVAC controller, etc. In some cases, menu options may be used to navigate to a menu that may allow a user to change an option that modifies subsequent operation and/or functionality of the thermostat  10 . 
     In some instances, the controller or processor of the thermostat  10  may be programmed such that first area  104  of the user interface display  100  displays one or more captions in a first line of text and a check box or other toggle box or other feature in a second row above or below the row with the one or more captions. An option displayed in the first area  104  with a caption may be selected by touching or pressing a button of the thermostat  10  and/or by touching an active touch area in the first area  104  of the user interface display  100 . The button may be an defined button in the second area  102 , a hard button that is situated adjacent to the screen, or any other suitable button. The active touch area in the first area  104  may be an active touch area associated with the displayed option and may take up the entire first area  104  or a portion of the first area  104  that is less than the entire first area  104 . Once an option displayed in the first area  104  is selected, a check box or toggle box may depict a selection has been made, for example, by displaying a check in a box, an X in a box, by filling in a box, and/or otherwise marking a box or about a box to indicate the displayed option has been selected. Additionally, or alternatively, a previously selected box may be deselected by touching or pressing a button of the thermostat and/or by touching an active touch area of the first area  104  that is associated with the displayed option. Such a display of options with a check box or toggle box may be utilized for selection of days of the week, holidays, and/or vacation days for setting a schedule, for setting which air sensors to use for sensing environmental conditions, and/or for any other option which may be selected and/or deselected. This is just one example of how an option may be selected. 
     In some instances, the controller or processor of the thermostat  10  may be programmed such that the message center (e.g., first area  104 ) may provide an instruction, a query, and/or a question or a sequence of instructions, queries, and/or questions (e.g., one or more queries or questions, two or more queries or questions, etc.) to a user viewing and/or using the message center. Additionally, or alternatively, the message center may be capable of accepting responses to queries and/or questions, which may be processed by the processor or controller of the thermostat  10 . Illustratively, responses may include a selection of a displayed option, entering text, and/or other responses in the first area  104  and/or the second area  102  of the interface display  100 , and/or via one or more hard buttons of the thermostat  10 . 
     In response to the acceptances of responses or answers, the thermostat  10  may configure the processor or controller to operate under one of the three control configurations discussed above, one or more of the two power configurations, and/or may configure the processor or controller of the thermostat  10  in one or more other manners. Illustratively, the questions or queries and/or the accepting of responses or answers may be part of one or more setup processes or other processes to identify one or more HVAC components to be controlled by the thermostat, to identify one or more thermostat settings, to identify one or more configuration settings, to identify one or more power configurations, etc. 
     Instructions, queries, and/or questions may be utilized for any purpose, for example, for setting up a schedule of operation for the thermostat. In such instances, example instructions, queries, and/or questions may include, but are not limited to: SELECT DAYS WITH SAME SCHEDULE.; PRESS NEXT AFTER SELECTING DAY. (e.g., after selecting a day, this new instruction may be displayed in the first area  104 ); IS SOMEONE HOME ALL DAY? NO OR YES (e.g., where NO and YES may have separate associated active touch areas and/or may be selectable by selecting a button in communication with a processor or controller of the thermostat  10 ); WHEN DOES THE FIRST PERSON WAKE UP?; WHEN DOES THE LAST PERSON LEAVE?; WHEN DOES THE FIRST PERSON RETURN?; WHEN DOES THE LAST PERSON GO TO SLEEP?; SET YOUR WAKE TEMPERATURE.; SET YOUR LEAVE TEMPERATURE.; SCHEDULE YOUR FAN TOO?; WAKE FAN SETTING.; LEAVE FAN SETTING; RETURN FAN SETTING; SLEEP FAN SETTING; SCHEDULE MORE DAYS?; REPEAT STEPS IF YOU WANT TO SCHEDULE MORE DAYS.; REVIEW SCHEDULE?; SAVING CHANGES.; and/or any other instructions, queries, and/or questions, as desired. 
     In some instances, the controller or processor of the thermostat  10  may be programmed or otherwise configured to display one or more options of the thermostat  10  in the first area  104  of the interface display  100  for selection by a user (e.g., selectable options), as referred to above. The processor or controller of the thermostat  10  may allow a user to select one or more options (e.g., select a single displayed option or select between two or more options, etc.), where the options may be displayed in the first area  104  of the thermostat  10 . 
     In one instance, the controller or processor of the thermostat  10  may be configured to display less than all of the two or more options (e.g., display one line of an option and less than a full line of another option) in the first region of the display at any given time. Any of the options or items displayed in the first area  104  may be available for selection by a user by one or more of touching the option and interacting with one or more buttons. 
     In some cases, the controller or processor of the thermostat  10  may be programmed or otherwise configured to animate one or more options or items displayed in the first area  104 . For example, animated options or items may include displayed options or items in the first area  104  that a user may scroll through. In one example, as a user scrolls through the displayed options or items, the options or items may appear to move in a vertical, horizontal, or vertical and horizontal direction, and/or any combination thereof including diagonal directions. Although the options or items may be animated in any manner, in some cases the animation of the one or more options or items may include incrementally moving the one or more options or items so that the one or more of the options or items appear to move in the first area  104  of the interface display. 
     In some instances, the first area  104  of the interface display  100  may display an option on a full line of text (e.g., an integer option) therein and one or more options on one or more partial lines of text above and/or below the full line of text. Illustratively, the presence of options listed on one or more partial lines of text above and/or below the full line of text may indicate to the user that there are additional available options by scrolling up and/or down, respectively. In instances when an option is displayed on a partial line of text below the full line of text, and no option is displayed above the full line of text, a top of the list may be indicated and further options may be displayed by scrolling down though the options. In instances when an option is displayed on a partial line of text above the full line of text, and no option is displayed below the full line of text, a bottom of the list may be indicated and further options may be displayed by scrolling up though the options. 
     The options or items displayed in the first area  104  may be scrolled through (e.g., in a direction of a partial line of text) and/or selected by interacting with a button of the thermostat  10  and/or touching the interface display  100  and interacting with the touch screen  46 . In some cases, interacting with and/or activation of a button of the thermostat  10  may cause the controller or processor of the thermostat  10  to selectively animate one or more of the options or items displayed in the first area  104 . The button(s) of the thermostat  10  may correspond to a physical button that may be offset from the interface display  100  and/or the button(s) of the thermostat  10  may correspond to a button region defined on the interface display  100  in one or more of the first area  104  and the second area  102 . In one example, the second area  102  may include one or more predefined touch regions, where each touch region of the second area  102  may correspond to a different button of the thermostat  10 . Illustratively, selection of a button (e.g., an arrow  114 ,  116  or other button) in the second area  102  of the user interface display  100  may cause the processor or controller to highlight a different selectable option in the first region of the user interface display  100  and touching the button multiple times may cause the processor or controller to highlight another selectable option in the first area  104  of the user interface display  100 . 
     In some cases, the options or items displayed on the first area  104  of the interface display  100  may be scrolled through and/or adjusted by touching the touch screen  46 . In one example, to scroll through and/or navigate between two or more selectable options, the processor or controller may be configured to recognize when a user touches the interface display  100  and moves along the touch screen  46  (e.g., moves along the touch screen  46  in a swiping manner, such as a dragging or pushing motion). In response to recognizing the movement along the touch screen, the two or more options may be animated and/or scrolled through in a vertical and/or horizontal manner. Additionally, or alternatively, the processor or controller of the thermostat  10  may recognize swiping motions on the touch screen  46  within the first area  104  of the interface display  100  and may display one or more next screens in a sequence of screens (e.g., when setting a schedule, when setting up the thermostat, and/or when using other sequences of screens). 
     In some cases, the processor or controller may be configured to accept a selection of a displayed option by detecting a user touch of the displayed selectable option via the touch screen  46 . In some cases, the processor or controller of the thermostat  10  may define an active touch area for each selectable option (e.g., touch selectable option) displayed on the display  44  of the thermostat  10  (e.g., a touch selectable option displayed on the first area  104  and/or the second area  102  of the interface display  100 ). The active touch area for each selectable option may or may not be viewable in normal use of the thermostat  10 . In one example, when two or more selectable options are displayed simultaneously on the first area  104  of the interface display  100 , the processor or controller may define an active touch area for each of the two or more selectable options such that if a user touches the interface display  100  within a defined active touch area the associated selectable option will be selected. 
     In some instances, the processor or controller may highlight a selected selectable option in response to receiving a user touch within an active touch area and/or in response to receiving any other selection signal for a particular selectable option or set of options. The highlighted portion  165  may represent the entirety of the active touch area associated with the selectable option, as best shown in  FIG. 34 . Alternatively, the highlighted portion may not represent the entirety of the active touch area associated with the selectable option. In one example of highlighting a selectable option, the processor or controller may be configured to highlight a selectable option response to receiving a first user touch at a position of the interface display  100  associated with a selectable option (e.g., within an active touch area) and then selecting the selectable option upon a second touch by a user or by a touch and hold by a user, where selecting the selectable option may include the thermostat  10  (e.g., the controller or processor thereof) performing an action associated with the selected selectable option. 
     In an illustrative method, a first selectable option may be displayed in the first area  104  of the interface display  100  of the thermostat  10 . A user may provide an input and the thermostat  10  may accept they input, where the input may correspond to interacting with the first selectable option. In response to accepting the input from the user, the controller may animate the first selectable option (e.g. move horizontally or vertically off the screen) and animate a second selectable option (e.g. move horizontally or vertically onto the screen) in the first area  104  of the interface display  100  of the thermostat  10 . Further, a user may provide an input that relates to the second selectable option, and the controller or processor of the thermostat  10  may accept the input from the user and select the second selectable option. In some instances, the second selectable option may be highlighted and/or a new display may be displayed in response to the selection of the second selectable option. 
     As shown for example in  FIG. 33 , and similarly shown in  FIG. 320 , an illustrative home screen  138  may be displayed on the interface display  100 . In the second area  102 , several active touch and/or interactive features may be displayed. For example, a time  140 , a following schedule indicator  142 , a current temperature  144 , a current humidity  146 , a scheduled temperature  148 , temperature setting arrows  150 , a home button  152 , a fan button  154 , a system button  156 , a menu button  158 , and/or other active and/or interactive features may be displayed in the first area of the interface display  100 . In the home screen  138  (see  FIG. 32O ), the first area  104  may be capable of displaying the active system (e.g., Heat, as shown for example in  FIG. 32O ) and  33 , Cool, Auto, Off, and/or other system) currently being controlled by the thermostat  10 . 
     In some instances and on some screens, the interface display  100  may include any number of fixed controls in the second area  102  to facilitate creating and/or modify text characters. For example, the interface display  100  may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. fixed controls in the second area  102 , as desired. In one example, the interface display  100  may include six (6) fixed controls in the second area  102 , as shown in  FIGS. 35 and 36  (e.g., with respect to a dealer name screen, but such fixed controls may be used with respect to other screens). The six (6) fixed controls in the second area  102  of  FIG. 35-36  may include, but are not limited to, a left arrow  134  and a right arrow  136  below the first area  104  to move within the text, an up arrow  114  and a down arrow  116  on the side of the first area  104  or other area to scroll through characters, and an up arrow  168  to switch from lower case letters to upper case letters (as shown for example in  FIG. 35 ) and a down arrow  166  to switch from upper case letters to lower case letters, (as shown for example in  FIG. 36 ). Alternatively, arrows  166  and  168  may facilitate switching between other types of character sets. In some cases, one or more (e.g., two (2)) buttons (e.g., a delete button  170  and a space button  172 ) may be positioned within the second area, which may be pressed or selected to create empty spaces before, after, and/or between characters and/or to delete characters. 
     Returning to  FIG. 33 , the second area  102  of the interface display  100  may include one or more active touch areas. For example, these active touch areas may include, but are not limited to the time  140  area which may be selected to go directly to a set time/set date screen, the current humidity level  146  area (e.g., a current indoor humidity level or a current outdoor humidity level) to go to a humidification screen, a dehumidification screen, or a menu listing HUMIDIFICATION and DEHUMIDIFICATION, the following schedule text area  142  which may be selected to go directly to a menu screen  174  (see  FIG. 34 ) with the EDIT SCHEDULE item highlighted, a READING AT REMOTE (not shown) text area which may be select to display the question CANCEL READING AT REMOTE? in the first area  104  of the interface display  100 , a program time area  194  (see  FIG. 47 ) in the view schedule mode which may be selected to revert the interface display  100  to the edit schedule mode (see  FIG. 40 ) in which the beginning time for time period of an HVAC system schedule may be set, the program temperature areas  178 ,  180  (see  FIG. 47 ) in the view schedule mode which may be selected to revert the interface display  100  to the edit schedule mode (see  FIG. 40 ) in which a temperature for a time period of an HVAC system schedule may be set, and/or other active touch areas utilized for other purposes, as desired. 
     In one example, when the thermostat  10  is setup for humidification and not dehumidification and a user presses or selects the current humidity level area  146 , the interface display  100  of the thermostat  10  may go directly to a humidification setting screen (not shown) from which a user may be able to adjust all humidification settings. In an example where the thermostat  10  is setup for dehumidification and not humidification and a user presses or selects the current humidity level area  146 , the interface display  100  of the thermostat  10  may go directly to a dehumidification setting screen from which a user may be able to adjust all dehumidification settings. In a further example, where the thermostat  10  is setup for humidification and dehumidification and a user presses or selects the current humidity level area  146 , the interface display  100  of the thermostat  10  may go directly to the menu screen  174  with a humidification item highlighted in the first area  104  of the interface display  100 . A user may then press or select the select button  160  to go to the humidification setting screen or scroll until the dehumidification item is highlighted and then press or selected the select button  160  to go to the dehumidification settings screen. 
     In some instances as discussed, the first area  104  may be an active touch sensitive area of the interface display  100 . Allowing the first area  104  to be an active touch sensitive area may allow for buttons, text, and/or other features in the second area  102  of the interface display  100  to be larger and/or easier for users to interact with. The active touch sensitive area of the interface display  100 , may be utilized for the following operations, among others: 1) select a system mode; 2) select a fan mode; 3) pressing on a highlighted item in a menu list in the first area  104  to go to a screen for the highlighted item; 4) pressing PRESS HERE TO START OCCUPANCY in the first area  104  to go to an occupied period when the thermostat is setup for Initiate Occupancy; 5) pressing an hour, a minute, a month, a day, a year numbers to make the pressed item the active item that can be changed by pressing or selecting the up button  114  and/or down button  116  when in a set time/date screen; 6) pressing the day, month, year numbers to make the pressed item the active item that can be changed by pressing or selecting the up button  114  and/or the down button  116  when in vacation mode to change the selected item when in vacation mode setup screens; 7) pressing a message of PRESS HERE TO RESET TIMER in the first area  104  to reset a reminder when reminders are selected from a preferences mode/screen; 8) pressing a message of 1 ALERT ACTIVE. PRESS HERE FOR INFORMATION in the first area  104  when an alert is active to go to more detailed information about the active alert; 9) pressing on a check box in the first area  104  for selecting a holiday when the thermostat is setup for commercial use; 10) pressing a message of PERIOD CANCELED, PRESS TO RESTORE in the first area  104  to restore a program period after it has been canceled when in the change schedule screen  182 ; 11) pressing a message of PRESS HERE TO EDIT in the first area  104  to enter custom reminder setup and/or dealer information setup during installer setup; and 12) pressing on the word DELETE or SPACE in the first area  104  to delete a letter or add a space, respectively, while in the custom reminder and/or dealer information setup screens. 
     In some instances, the first area  104  may be navigated with swiping movements and/or direct interaction with features therein. In one example, in addition to or as an alternative to using an up arrow  114 , a down arrow  116 , a left arrow  134 , a right arrow  136 , a back button  118 , a next button  120 , and/or other feature adjacent the first area  104 , a user may be able to swipe their finger(s), a stylus or other tool across and/or within the first area  104  to move to a next screen and/or scroll through a list. The list may move in an animated manner, if desired, to help give the visual effect of scrolling through the list the swiped direction. Alternatively, or in addition, a user may be able to highlight and/or select one or more options listed in the first area  104  by touching the one or more desired options within the first area  104  with a finger(s), a stylus and/or other tool. 
     The thermostat  10  may use one or more of several menus to access user settings and/or installer settings. From the home screen  138  (see  FIG. 33 ) and/or other screens, these menus may be accessed by selecting the menu button  158 . Once the menu button  158  has been selected, a list of menus may be displayed in the first area  104  of the interface display  100 , which may be scrolled through with the up arrow  114  and/or the down arrow  116  as shown in for example  FIG. 34 . The list of menus may include, but is not limited to: EDIT SCHEDULE, VIEW SCHEDULE, VACATION MODE, HOLIDAY SCHEDULE, HOLIDAY MODE, EQUIPMENT STATUS, DATE/TIME, PREFERENCES, CLEAN SCREEN, SECURITY SETTINGS, DEALER INFORMATION, INSTALLER OPTIONS, MAIN MENU, INSTALLER SETUP, WIRELESS MANAGER and/or other menus. 
     When a desired menu item is highlighted (e.g., EDIT SCHEDULE, as shown in  FIG. 34 ), a select button  160  positioned in the second area  102  or other area of the interface display  100  may be pressed or selected to go to a screen for the highlighted menu item. Alternatively, or in addition, a user may tap the first area  104  to select the highlighted menu item. Once a menu item has been selected, further sub-menu items or options may be provided that are classified under the selected menu item and/or the interface display  100  may allow for a respective adjustment to thermostat  10  in response to the selection. 
     The menus of thermostat  10  depicted in the first area  104  of the interface display  100  may have vertical animation that may allow for scrolling through the lists of menus and/or options. Although the first area  104  may only display two (2) lines of text, the first area  104  may display virtually any number of items in a menu list. In some instances, the first area  104  may display the list such that a first item  162  on the list is entirely viewable and a second item  164  on the list is only partially viewable (see  FIG. 34 ). The partially viewable item on the list may indicate to the user that there are further items in the list. The partially viewable item may be below or above the fully viewable item. 
     The vertical animation may allow the list of menu items to be scrolled through by pressing or selecting the down arrow  116  and/or the up arrow  114 , while allowing a user to visually see that they are moving up or down through the menu list. Pushing the down arrow  116  may make the menu list move up, which in turn may make a user think they are heading to the bottom of the menu list. Pushing the up arrow button may make the menu list move down, which in turn may make a user think they are heading to the top of the menu list. 
     In some instances, the vertical animation may facilitate a user in distinguishing between two similar menu items or menu items that may have the same name. Because the menu item may appear to physically move when the up arrow  114  and/or the down arrow  116  are pressed, the user may be able to see that they have moved onto the next menu item in the list. In one example, when a user is in a WIRELESS MANAGER menu and is viewing connected devices including multiple indoor sensors with the same or similar name, if the first area  104  did not have vertical animation, the user may not be able to tell how many remote indoor sensors are connected to the thermostat because the screen would not change at all when the up arrow  114  and/or the down arrow  116  are pressed or selected in a static screen. Rather than scrolling through the menu items using one or more buttons in the second area  102 , it is contemplated that a user may scroll through the items by making a swiping gesture in the first area  104 , as further described herein. 
     Similar to the vertical animation of first area  104  of the interface display  100 , the first area  104  may have and/or utilize horizontal animation. The horizontal animation of the first area  104  may be utilized to visually indicate when a user is moving forward or moving backward in a setup process or other process. In one example, when a next button  120  is pressed or selected, the text in the first area  104  may slide to the left and when the back button  118  is pressed or selected, the text in the display may slide to the right. The horizontal animation may be used in, among other places, installer setup, program scheduling (e.g., when using a scheduling assistant), setting a vacation hold, etc. 
     Upon initial set up when the thermostat  10  is first powered on and/or at other times, the interface display  100  may take a user (e.g., a contractor or other user) through an enrollment scheme  106 . As shown for example in  FIG. 31 , the enrollment scheme  106  may include a connection setting portion  108 , an accessory enrollment portion  110  (e.g., a RedLINK™ enrollment portion that may include identification of the thermostat(s) and/or accessories), and a thermostat setup portion  112 . 
     The connection setting portion  108  may include one or more of several screens depicted on the interface display  100 , where each step or screen may have a Setup# area  124 . As shown for example in  FIG. 32A , one screen may allow a user to select the application in which the thermostat  10  will be primarily used (e.g., residential, commercial, or other use of the thermostat  10 ) in setup # 101 . The application may be selected by scrolling through a list of applications (e.g., residential, commercial, etc.) and when the application is highlighted in the first area  104 , a next button  120  (e.g., a button may be a mechanical button or, as shown in the Figures, may be a button on the touch sensitive interface display  100 ) may be pressed or selected to go to a next screen. 
     Once an application has been selected, the connection setting portion  108  may ask a user to select a device name for thermostat  10  in Setup # 103 , as shown for example in  FIG. 32B .

Alternatively, if it is desired to go to a previous screen, the back button  118  may be selected. If help is needed in selecting a device name, a help button  122  may be selected whereupon additional help information may be displayed to the user in the first area  104 . 
     Once a device name has been selected, the connection setting portion  108  may ask a user to select whether the HVAC system is zoned in Setup # 110 , as shown for example in  FIG. 32C . A user may scroll between YES and NO with the up arrow  114  and/or down arrow  116 . The YES or NO option may be selected when the desired option is highlighted in the first area  104  and a next button  120  is pressed or selected to go to a next screen. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     If the HVAC system is not zoned, the accessory enrollment portion  110  may ask a user to select whether the thermostat  10  controls an equipment module in Setup # 120 , as shown for example in  FIG. 32D . A user may scroll between YES and NO with the up arrow  114  and/or down arrow  116 . The YES or NO option may be selected when the desired option is highlighted in the first area  104  and a next button  120  is pressed or selected to go to a next screen. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     If an equipment module system is not used, the accessory enrollment portion  110  may ask a user to select whether to connect accessories to the thermostat  10 , as shown for example in  FIG. 32E . A user may select a YES button  128  or a NO button  130  in the second area  102 . 
     If no accessories will be connected to the thermostat  10 , the thermostat setup portion  112  may ask a user to press or select a NEXT button  120  to begin installer setup, as shown for example in  FIG. 32J . In some instances, the interface display  100  may display a message in the first area  104  or any other area indicating PRESS NEXT TO BEGIN THE INSTALLER SETUP OR INSERT A MICROSD CARD NOW TO SETUP THE THERMOSTAT. Alternatively, one or more other messages may be displayed. If a memory card is to be used for thermostat setup, a user may insert a memory card (e.g., a microSD card) to setup the thermostat  10 . 
     If accessories are to be connected to the thermostat  10 , the accessory enrollment portion  110  may ask a user to TURN ON 24 VAC POWER NOW, THEN PRESS NEXT. 24 VAC IS REQUIRED TO CONNECT REDLINK™ ACCESSORIES, as shown for example in  FIG. 32P . In some instances, only two (2) lines of the message may be displayed in the first area  104 , as shown for example in  FIG. 32P , and the down arrow  116  and/or the up arrow  114  may be selected or pressed to scroll through the rest of the message. If it is desired to go to a previous screen, the back button  118  may be selected. 
     Once the power has been turned on and the next button  120  has been selected or pressed, an enroll mode may be entered and a screen may be displayed indicating the system is preparing to add a device, as shown for example in  FIG. 32Q . If it is decided that a device will not be added at this time, a cancel button  132  may be pressed or selected and the system will go to the thermostat setup portion  112 . If it is desired to add a device, once the systems has been prepared to add a device, the interface display  100  will be displayed asking a user to press connect a new accessories, as shown for example in  FIG. 32R .

If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Once it has been indicated that the system is zoned, and that the thermostat  10  controls an equipment module system by selecting YES in the screen of  FIG. 32T , the accessory enrollment portion  110  may ask a user to press or select a next button  120  to begin connecting the thermostat  10  to the equipment module, as shown for example in and discussed with respect to  FIGS. 32F-32I . 
     In instances where the equipment interface module and a humidity sensor accessory or other accessory are to be used, substantially all or all of the relays and inputs on the interface module may be used. In one example, the thermostat  10  standing alone (e.g., as a host) may only work with a three (3) heat/two (2) cool heat pump system or a two (2) heat/two(2) cool conventional system, but when the thermostat  10  is used with the equipment interface module (e.g., a client), the thermostat  10  may control a four (4) heat/two(2) cool heat pump or a three (3) heat/two (2) cool conventional system. As such, in some cases, the functionality and/or capability of the thermostat  10  may increase once it is linked with an equipment interface module. 
     In another example, if the thermostat  10  is used as a standalone thermostat, there may only be one (1) input terminal for an indoor sensor, an outdoor sensor, and/or a discharge sensor. When the thermostat  10  is connected with the equipment interface module, the thermostat  10  may service for four (4) input terminals which may be used with an indoor sensor, an outdoor sensor, a discharge sensor, a return sensor, a dry contact device for remote setback, a dry contact device to display alerts, and/or one or more other accessories. 
     In another example, if the thermostat  10  is used as a standalone thermostat, it may be able to control one of the humidification, dehumidification, or ventilation. When the thermostat  10  is connected with the equipment interface module, however, the thermostat  10  may be setup to control humidification, dehumidification, and/or ventilation. 
     Once it has been indicated that the system is zoned and that the thermostat  10  does not control an equipment interface module system by selecting NO in the screen of  FIG. 32T  or after the accessory and/or equipment interface module setups are complete, the accessory enrollment portion  110  may ask a user to select whether the thermostat  10  is wirelessly connected to a zone panel in Setup # 125 , as shown in  FIG. 32U . A user may scroll between YES and NO with the up arrow  114  and/or down arrow  116 . The YES or NO option may be selected when the desired option is highlighted in the first area  104  and a next button  120  is pressed or selected to go to a next screen. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Once it is indicated that the thermostat  10  is wirelessly connected to a zone panel, the accessory enrollment portion  110  may ask for a zone number to setup in Setup # 102 , as shown for example in  FIG. 32W . In some instances, the interface display  100  may display a message in the first area  104  or any other area indicating ZONE NUMBER followed by a list of numbers. In some cases the list of zone numbers may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, and/or any other number of zones, as desired. Alternatively, one or more other messages may be displayed. Once the desired zone number is highlighted, the next button  120  may be selected or pressed to connect the thermostat  10  as the selected zone to the wireless zone panel. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Once the zone number for the thermostat  10  has been selected, interface display  100  may show a message indicating PRESS CONNECT AT ZONE PANEL, THEN PRESS NEXT, as shown for example in  FIG. 32X . Alternatively, or in addition, any other message may be displayed. In some instances, only two (2) lines of the message may be displayed in the first area  104  and the down arrow  116  and/or the up arrow  114  may be selected or pressed to scroll through the rest of the message. The next button  120  may be selected to begin connecting the thermostat  10  to the wireless zone panel. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Once the next button  120  has been select to connect the thermostat  10  to the wireless zone panel, the interface display  100  may display a screen indicating that the thermostat is being connected to the wireless zone panel by displaying a message indicating CONNECTING THERMOSTAT in the first area  104  or other area. 
     If the connection of the thermostat  10  to the wireless zone panel is unsuccessful, a screen may display a message indicating that the connection failed, as shown for example in  FIG. 32AA . If the connection failed due to no response or a weak signal, the screen may show a message indicating CONNECTION FAILED. VERIFY THE CONNECT LED ON THE WIRELESS ZONE PANEL IS FLASHING AND YOU ARE AT LEAST 2 FEET AWAY. TRY CONNECTING AGAIN. If the connection failed due to an incompatible instance, the screen may show a message indicating CONNECTION FAILED. THIS ZONE IS CURRENTLY SET TO “WIRED” AT THE ZONE PANEL. PLEASE SET THIS ZONE TO “RF” AND TRY AGAIN. If the connection failed due to an invalid instance, the screen may show a message indicating CONNECTION FAILED FOR ONE OF TWO REASONS. THE ZONE NUMBER SET ON THE THERMOSTAT DOES NOT MATCH THE ZONE NUMBER ON THE TRUEZONE™ PANEL. PLEASE SET THE CORRECT ZONE NUMBER ON THE THERMOSTAT.

If it is desired to exit from installer options, a cancel button  132  may be selected. 
     After correctly entering a password or passcode, the interface display  100  may display a list of installer set up items in the first area  104  in an installer menu screen  204 , as shown for example in  FIG. 38 . The installer setup items list may include, but are not limited to, INSTALLER SETUP, INSTALLER TEST, DATA LOSS, WIRELESS MANAGER, RESET TO DEFAULTS, DEVICE INFO, etc. The list of installer setup items may be scrolled through with the up arrow  114  and/or the down arrow  116  and a highlighted item may be selected by pressing the select button  160  or tapping the first area  104 . If it is desired to go to a previous screen, the back button  118  may be selected or pressed. If help is needed, the help button  122  may be selected or pressed. 
     In some instances, one or more (e.g., two or more, three or more, each) of the installer setup items may be displayed in the first area  104  with a name that describes the feature being set and/or value of an effective setting of the particular item. Once an INSTALLER SETUP item is selected, each item or step of the installer setup may have a setup number displayed in a set up number area  124  in the second area  102  of the interface display  100 , as shown for example in  FIGS. 32A-32C , which may provide a unique identifier of each installer setup item or step. 
     In some cases, an installer setup item name and value may be display in the first area  104  of the interface display  100 . For example, the installer setup item name may be displayed on a first line of text in the first area  104  and the installer setup item value may be displayed on a second line of text in the first area  104 . 
     The processor or controller of the thermostat  10  may be configured to animate the installer setup item name and/or value when these features are optionally simultaneously displayed in the first area  104  of the interface display  100  in a vertical, horizontal, and/or any other direction. In one example of displaying installer setup items, when the installer setup item name is switched between a displayed first installer setup item and a second installer setup item (which may or may not be simultaneously displayed with the first installer setup item), the processor or controller may be configured to animate the installer setup items in a horizontal direction or a vertical direction to display the second installer setup item name. In another example, when switching between a displayed first predefined installer setup item value and a second predefined installer setup item value (which may or may not be simultaneously displayed with the first predefined installer setup item value), the processor or controller may be configured to animate the predefined installer setup item values in a vertical and/or horizontal direction to display the second predefined installer setup item value. Illustratively, switching installer setup item names and/or values (e.g., predefined installer setup item values) in an animated manner may be effected through touching and/or swiping an active touch area associated with the installer setup items in the first area  104  of the interface display  100 , touching a button offset from the interface display  100  (e.g. a hard button), and/or touching an active touch area of one or more buttons (e.g., predefined buttons such as arrows  114 ,  116  or other buttons) in the second area  102  of the interface display  100 . 
     The animation of the installer setup items may be utilized to dynamically adjust which installer setup items from a plurality of predefined installer setup items are displayed (e.g., displayed in a sequential manner). Illustratively, dynamic adjustment of installer setup item names and/or values may include adjusting the displayed installer setup item names and/or values for an installer setup item based on one or more installer setup item values selected for a previous setup item. 
     In an illustrative method of setting up an HVAC controller, two or more installer setup items may be sequentially displayed on the interface display  100  (e.g., in the first area  104  of the interface display  100 ). In some cases, each of the sequentially displayed installer setup items may include an installer setup item name and value that may be displayed in the first area  104  of the interface display  100 . Further, the method may include accepting a selection of a predefined fixed segment icon of a first button in the second area  102  of the interface display  100 . Selection of the predefined fixed segment icon in the second area  102  may include touching the first button therein, which may cause the processor or controller of the thermostat  10  to display a predefined installer setup item name and/or value that was not previously displayed in the first region of the interface display  100 . Illustratively, with each selection of a button in the second area  102  of the interface display and the display of the installer setup item name and/or value in the first area  104 , a setup item number that is associated with the displayed installer setup item name and/or value may be displayed in the second area  102  of the interface display  100 . Additionally, or alternatively, the method may include dynamically adjusting which installer setup items from a plurality of predefined installer setup items are sequentially display, where the dynamically adjusting of the displayed predefined installer setup items may be in response to, and may depend upon, a previously selected installer setup item or other selection of any other option. 
     As discussed herein, the installer setup may be dynamically adjusted to fit the system capabilities in view of previous settings and may allow for a reduced number of setup items shown to a user because only those settings that are relevant are displayed based on previous selections. For example, if a previous selection indicates that no humidification system is present, settings related to a humidification are not displayed. As discussed throughout this disclosure, the up arrow  114  and/or the down arrow  116  in the second area  102  to the side of the first area  104  may be used to adjust values and navigating between setup items may be facilitated by using the back button  118  and/or the next button  120 . 
     Once the installer setup of the thermostat setup portion  112  has been entered and a screen, as shown for example in  FIG. 32J , is depicted on the interface display  100  displaying the message PRESS NEXT TO BEGIN THE INSTALLER SETUP OR INSERT A MICROSD CARD NOW TO SETUP THE THERMOSTAT. Alternatively, or in addition, one or more other messages may be displayed. If a memory card is to be used for thermostat setup, a user may insert a memory card (e.g., a microSD card) to setup the thermostat  10 , wherein the thermostat setting may be downloaded from the memory card rather than entered/selected manually by the user. 
     Once installer set up has begun, the thermostat setup portion  112  may ask a user to select the thermostat type for thermostat  10  in Setup # 104 , as shown in  FIG. 32K . One or more thermostat types may be in a list through which a user may scroll with the up arrow  114  and/or down arrow  116 . The list may include, among other options, PROGRAMMABLE and NON-PROGRAMMABLE. The thermostat type may be selected by scrolling through the list of thermostat types and when the desired thermostat type is highlighted in the first area  104 , a next button  120  may be pressed or selected to go to a next screen. If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Once a thermostat type has been selected, the thermostat setup portion  112  may ask a user to select the temperature scale for thermostat  10  in Setup # 105 , as shown in  FIG. 32L . One or more temperature scales may be in a list through which a user may scroll with the up arrow  114  and/or down arrow  116 .

If it is desired to go to a previous screen, the back button  118  may be selected. If help is needed, a help button  122  may be selected. 
     Installer setup and the interface display  100  may be used to set up one or more sensors internal to the thermostat  10  and/or one or more remote indoor temperature sensors for temperature control, as shown for example in  FIG. 39A-39D  depicting Setup#  504 . In some instances, the first area  104  of the interface display  100  may display YES/NO questions that may allow a user to setup the thermostat  10  to sense a temperature only at the thermostat  10  for temperature control, sense at one of one or more remote indoor sensors (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, etc.) for temperature control, where any connected indoor temperature sensor may be selected, or average any or all of the temperature sensors (e.g., the temperature sensor(s) internal to the thermostat  10  and/or the remote indoor temperature sensors) for temperature control. When multiple remote indoor sensors are connected to the thermostat  10 , the first area  104  of the interface display  100  may display the name provided to each of the remote indoor sensors. 
     As shown for example in  FIG. 39A , when setting up the temperature sensor for temperature control, the first area  104  of the interface display  100  may display USE T-STAT SENSOR TEMP CONTROL and allow a user to select YES or NO. If NO is selected, the first area  104  of the interface display  100  may display USE INDOOR SENSOR [or other sensor name] FOR TEMP CTRL and allow a user to select YES or NO, as shown for example in  FIG. 39D . The thermostat  10  may continue to display messages in the first area  104  of the interface display  100  inquiring which temperature sensor(s) to use for temperature control. Once a temperature sensor has been selected for temperature control, the first area  104  of the interface display  100  may display USE INDOOR SENSOR [or other sensor name] IN TEMP AVG and allow a user to select YES or NO, as shown for example in  FIGS. 39B and 39C . If yes is selected, the temperature sensor may be used by the thermostat  10  in averaging temperatures from one or more temperatures sensors for temperature control. If NO is selected, the measurements from the temperature sensor will not be used in the temperature average utilized by the thermostat  10  for temperature control. If NO is selected for all of the temperature sensors, the thermostat  10  may remove the next button  120  and/or the done button  126  from the second area  102  of the interface display  100  at the last question, which may force a user to go back and select a temperature sensor for temperature control by the thermostat  10 . Alternatively, the thermostat  10  may automatically select a temperature sensor to use for temperature control if one is not chosen (e.g., the temperature sensor internal to the thermostat  10 ). Similar selection of temperature sensors connected to the thermostat  10  may be utilized by thermostat  10  for humidification control, dehumidification control, and/or controlling of other features. Allowing for the optional selection of temperature sensors connected to the thermostat  10  for controlling different system, may allow a user to determine which sensor will be used to control which systems or features of an HVAC system. 
     When it is desired to exit the installer setup of the thermostat setup portion  112 , the done button  126  depicted in some or all of the screens of the installer setup may be selected or pressed. After selecting the done button  126 , a screen may display a message asking DO YOU WANT TO EXIST INSTALLER SETUP?, as shown for example in  FIG. 32M .

     When the thermostat  10  is in a view schedule mode, the interface display  100  of the thermostat  10  may automatically group the days that have the same schedule by showing a check mark or other marking in or about the day buttons  176  (e.g., Mon, Tue, Wed, Thu, Fri, Sat, Sun) displayed in the second area  102  of the interface display  100 , as shown for example in  FIG. 40 . In one example, if Monday, Tuesday, and Wednesday have the same HVAC system schedule, Thursday and Friday have the same HVAC system schedule, and Saturday and Sunday have the same HVAC schedule, the interface display will show check marks or other markings in the day buttons  176  for Monday (Mon), Tuesday (Tue), and Wednesday (Wed) indicating these days have the same HVAC system schedule, as shown for example in  FIG. 41 . If a user presses on either of the day buttons  176  for Thursday (Thu) or Friday (Fri), the second area  102  of the interface display  100  will show check marks or other markings in the day buttons  176  for both Thursday (Thu) and Friday (Fri) indicating these days have the same HVAC system schedule, as shown for example in  FIG. 42 . If a user presses on either of the day buttons  176  for Saturday (Sat) or Sunday (Sun), the second area  102  of the interface display  100  will show check marks or other markings in the day buttons  176  for both Saturday (Sat) and Sunday (Sun) indicating these days have the same HVAC system schedule, as shown for example in  FIG. 43 . 
     While verifying a schedule, if a user would like to make a change, the user may interact with the first area  104  of the interface display  100 , a heat temperature  178 , a cool temperature  180 , or other feature displayed on the interface display  100  to view and/or interact with a change schedule screen  182 , as shown in for example  FIG. 44 . From the change schedule screen  182 , the day buttons  176  may be selected to add and/or delete a day from a schedule (e.g., see  FIGS. 44, 45, 46 ), change temperature settings for heating and/or cooling by selecting or pressing the temperature setting arrows  150 , change a time associated with a Wake setting by selecting or pressing time setting arrows  196 , change a time associated with a Leave setting by selecting or pressing time setting arrows  196 , change a time associated with a Return setting by selecting or pressing time setting arrows  196 , change a time associated with a Sleep setting by selecting or pressing time setting arrows  196 , modify a fan setting by selecting or pressing a fan setting button  198 , and/or cancel time period for the schedule by selecting or pressing the cancel period button  200 . In some instances, the first area  104  of the interface display  100  may indicate which setting is being modified. For example, the first area  104  of the interface display  100  in the change schedule screen may display which time period settings are being changed (e.g., SET WAKE TIME &amp; TEMPERATURE, as shown for example in  FIGS. 44-46 ). When the HVAC system settings have been modified, selecting the done button  126  may save the modifications and return the thermostat  10  to a view schedule mode, and interface display  100  may display the view schedule mode screen  184 . Alternatively, the thermostat  10  may display a different screen on the interface display  100  after selecting the done button  126 , such as the home screen  138  or other screen. 
       FIGS. 49A-49F  depicts an illustrative flow  400  of screens for the interface display  100  when interacting with a weather mode of the thermostat  10  accessible from the menu screen  174  when weather information is available.  FIG. 49G  depicts an illustrative flow  500  when interacting with a weather mode of the thermostat  10  accessible from the menu screen  174  when weather information is not available. Although  FIGS. 49A-49G  depict illustrative flows of the weather mode of the thermostat  10 , other flows may be available, as desired, for navigating the weather mode. 
     The weather mode of the thermostat  10  may display weather related information about today&#39;s forecast, todays actual weather readings (e.g., temperature, humidity, dew point, wind chill, wind direction, wind speed, weather warnings, weather watches, etc.), today&#39;s forecast description, forecasts for future time periods, and/or forecast descriptions for future time periods. Illustratively, forecast descriptions may include, but are not limited to, SUNNY, MOSTLY SUNNY, PARTLY SUNNY, PARTLY CLOUDY, HAZY SUNSHINE, MOSTLY CLOUDY, CLOUDY, DREARY, FOGGY, SHOWERS, THUNDERSTORMS, THUNDER SHOWERS, RAIN, FLURRIES, SNOW, ICE, SLEET, FREEZING RAIN, RAIN AND SNOW, HOT, COLD, AND/OR WINDY. 
     As shown in  FIG. 49A , screen  402  depicts a home screen  138  as described herein. From the home screen  138 , a menu button  158  may be selected to move to screen  404 . In screen  404 , a list of menu options may be displayed in the first area  104 . The list of menu options may be scrolled through by swiping within the first area  104  and/or by selecting the up arrow  114  and/or the down arrow  116 . A user may scroll until the menu option WEATHER is highlighted. By touching either the highlighted menu option or by touching the select button  160 , today&#39;s weather and/or weather forecast may be displayed in the first area  104  of the interface display  100  in screen  406 , as shown in  FIG. 49B . To view further forecast and/or weather information for today, a user may select the up arrow  114  and/or down arrow  116  and view the complete forecast in the first area  104 , as shown in screens  420  ( FIG. 49B ),  422  ( FIG. 49C ), and  424  ( FIG. 49C ), which depict current weather readings. In some instances, a weather icon may be displayed in the second area  102 , which when touched, may cause the weather information to be displayed in the first area  104 . 
     In some instances, weather forecasts and forecast descriptions for future days or time periods may be shown. The number of future days or time period for which forecasts may be viewed may be any number, for example, the thermostat  10  may be able to display weather forecasts for up to one day, two days, three days, four days, five days, six days, seven days, and so on. To view weather forecasts for future days, the next button  120  may be selected in any one of screens  406 ,  408 ,  410 ,  416 ,  418 ,  420 ,  422 , and/or  424 . If a user selects the next button  120  from one or more of screens  422  and  424 , a user is brought to screen  408  depicting the weather forecast for tomorrow, as shown in  FIG. 49D . When a user gets to a screen depicting the last day for which a weather forecast is available, such as in screens  412 ,  414  ( FIG. 44F ), the next button  120  may be removed from the interface display  100  and/or may not be an active touch area. To view a previous day&#39;s forecast, a user may touch the back button  118 . When a user is finished viewing the weather and weather forecast information in the weather mode, the user may select the done button  126  to return to the menu in screen  404  or return to the home screen  138  in screen  402 . 
       FIG. 49G  depicts a flow  500  of entering a weather mode when weather information is unavailable to the thermostat  10 . From the menu screen  502 , weather may be selected in the first area  104  of the interface display  100 . When the weather mode is selected from the first area  104  and weather information is unavailable, screen  504  may be displayed and the first area  104  may indicate weather information is CURRENTLY NOT AVAILABLE. A user may then select the done button  126  to return to the menu screen  175  or the home screen  138 . 
     Screens, buttons, and/or other features of the interface display  100  that are not particularly described, but appear to be similar to screens, buttons, and/or other features of the interface display  100  that are particularly described, are to be interpreted in the same manner as the similarly appearing screens, buttons, and/or other features particularly described with respect to the interface display  100 . Additionally, if a feature is shown in one screen, but not another screen, such omitting of the feature does not mean it cannot or is not included in another screen. The highlighted (e.g., grayed) buttons depicted in the illustrative screens are pressed or selected to move onto a next screen (e.g., a next screen may moving forward in the flow, moving backward in the flow, or jumping out of order in the flow). If more than one button is highlighted in a single screen of the interface display  100 , the flow diagram is depicting which screen of the interface display  100  is next for each button selection.
