       BACKGROUND 
       [0003]    HVAC control systems are used to control the environment within a building and are more frequently linked via the internet for web-enabled building control. The internet connection allows receipt of instructions from a remote and/or mobile device. However, there are many levels of complexity that can lead to difficult implementation and use of such controllers. For example, many wireless network communication protocols exist, such as Bluetooth, DSRC, EnOcean, IrDA, Redlink, RFC, Wi-Fi or Zigbee®. These wireless network communications must reliable link to components such as routers, hubs, sensors, computers, mobile phones or tablets and thermostats. A multitude of software and graphical user interfaces may be used to attempt to set-up and control the systems. All of this complexity can lead to layers of technical problems for the system installers and unsophisticated users. In particular, many users have difficulty with set-up procedures when there are a multitude of steps required to link the components of the system. The present invention overcomes many of such difficulties and provides for easy set-up and synchronization between a remote device and a HVAC control.

       [0014]    While the invention is amenable to various modifications and alternate forms, specific embodiments have been shown by way of example in the drawings and will be described in detail, it should be understood that the intention is not to limit the invention to the particular embodiments described. The intention is to cover all modifications, equivalents and alternatives falling within the spirit and the scope of the invention. 
       DETAILED DESCRIPTION 
       [0015]    Turning to  FIGS. 1-13 , an embodiment of the invention will be described.  FIGS. 1-11  depict screen shots of set-up displays that will be described in sequence according to the steps provided in  FIG. 12 .  FIG. 1  depicts a remote input device (RID) such as a Smartphone or other device that is capable of transmissions using Wi-Fi or WLAN under IEEE Communication Standard 802.11, or any other well-known wireless communication system. It is well known to use encryption means to send data and each of the data transmissions described below may be encrypted and decrypted. The RID may include a computer, tablet, phone, laptop, notebook, wireless computer, wireless tablet, wireless phone, wireless laptop or wireless notebook. The device  10  includes a touchscreen  15  including a data input area  18  and keypad area  20 . Using well known systems such iPhone apps or Play apps from Google, or other well-known methods, the user starts the process at step  101  loading the (BlueLink™) application on a mobile device  10 . 
         [0016]    The display screen  18  depicts account registration screen 1 of 4 and includes empty input blocks for “Email” and “Confirm email” input blocks. A user types on the keypad  20  in order to input their email address. This coincides with Step  102  of  FIG. 12 . While the display screens of  FIGS. 1-11  have specific graphical user interface (GUI) layouts, the invention may be implemented using other types of GUIs and layouts. The invention may also be implemented with similar set-up commands via a web page on a remote input device including wired or wireless computers and/or wireless smartphones or tablets. 
         [0017]    Turning to  FIG. 2 , the account registration screen 2 of 4 is depicted in the display area  18  and the user inputs a password and confirms the password in accordance with Step  103  of  FIG. 12 . 
         [0018]    Turing to  FIG. 3 , the account registration screen 3 of 4 is depicted in the display area  18 . Note that the keyboard area  20  has been removed and in this embodiment a time zone is selected by touching the screen. For example, when the “Pacific Time Zone” is selected, it will be highlighted in grey. This step is shown in  FIG. 12  as Step  104 . 
         [0019]      FIG. 4  depicts account registration screen 4 of 4 where the user agrees to the terms and conditions by pressing the “Agree” button or reviewing terms and conditions by pressing the “Terms and Conditions” button on the display area  18 . This coincides with Step  105  of  FIG. 12 . 
         [0020]    At  FIG. 5 , account registration screen 4 of 4 (continued) is displayed and allows the user to register by pressing the “Register” button on the display area  18  or to cancel the transaction by pressing the “Cancel” button. This coincides with Step  106  of  FIG. 12 . Upon selecting the Register button, the new user information will be transmitted. 
         [0021]    Turing to  FIG. 12 , following the transmission of the new user information to a cloud server  201  ( FIG. 13 ) configured to handle transactions for this system (BlueLink), a new user account is created. Well-known means of creating customer accounts using software tools may be accomplished at this Step  107 . At Step  108 , the server sends a message that the account has been created successfully. As depicted in  FIG. 6  on the display area  18  of the mobile device  10 , a window is opened that states “Account Successfully Created” 19 . Other alerts that may be posted via the mobile device  10  include “No Valid Internet Connection,” “Communication Loss,” “Unknown Error,” or other types of alerts. At the next Step  109 , the screen display area  18  changes and the keyboard area  20  is redisplayed so that the user can input the serial number of a thermostat or building environment control device. The user may view the back of the thermostat  210  ( FIG. 13 ),  401  ( FIG. 14 ) or user manual or authentication card where the serial I.D. number is displayed. Using the keypad  20 , the user will enter the number in the block area in the display section  18  of the mobile device  10  as depicted in  FIG. 7 . 
         [0022]    At Step  110 , the device name is input by use of the keypad  20  and putting the user&#39;s desired name for the thermostat. For example, a default name of “Thermostat” will be used and if another name is entered, the default will be “Thermostat  2 ” and if a third default name is entered, the system will use the name “Thermostat  3 ”, etc., as shown in  FIG. 8 . In an alternate manner, the user may identify the thermostat as “Living Room,” “Dining Room,” “Family Room,” “Bedroom,” etc. 
         [0023]    At Step  111 , the synchronization of the system to work with a Wi-Fi network is depicted. As shown in  FIG. 9 , a display of local Wi-Fi networks is displayed and the user can select the appropriate Wi-Fi network by indicating with a fingertip on the touchpad display. For example, in  FIG. 9 , the user has selected “Braeburn Home Network” and that bar is highlighted in a darker color. The Wi-Fi network is provided by a local router  407  ( FIG. 14 ) or other web enabled control device. Once the user has selected the preferred home network, they can depress the Enter button. 
         [0024]    At Step  112 , the application receives the identification of the Wi-Fi network to be used. At Step  113 , the password for the Wi-Fi network is input into the display area  18  of the remote/mobile device  10 . Once the application receives the password via input screen as shown in  FIG. 10 , the application will activate the communication via the Wi-Fi network to the thermostat and at Step  114  the thermostat device is put into an active listening mode. User input to the thermostat places the thermostat  210 ,  401  in the listening mode. 
         [0025]    At Step  115 , a display is provided by the mobile device that a connection is being made to the thermostat device  210 ,  401 . At Step  116 , a P2P set-up protocol is communicated to the application running on the thermostat  210 ,  401 . 
         [0026]    At Step  117 , a display appears on the mobile device that the connection is successful as depicted at  17  in display area  18  depicted in  FIG. 11 . At Step  118 , the application will transfer the Wi-Fi network selection and Wi-Fi password to the thermostat  210  ( FIG. 13 ),  401  ( FIG. 14 ) to set-up the thermostat  210  for control from the RID. This provides the set-up of the thermostat in one step. 
         [0027]    At Step  119 , the thermostat device  210 ,  401  is set up according to the instructions from a server via communication from the Wi-Fi network  407  ( FIG. 14 ). At Step  120 , the mobile device  10  transmits information to the server  411  via the Cloud ( FIG. 14 ). At Step  121 , the Cloud server  411  associates the user&#39;s mobile device via a unique serial number so that the mobile device  10  and the thermostat  210  ( FIG. 13 ),  401  ( FIG. 14 ) are synchronized. 
         [0028]    At Step  122 , a display on the mobile device  10  is displayed that the connection between the thermostat  210 ,  401  and the mobile device has been successful. At Step  123 , the thermostat device  210 ,  401  is added to the app device list of the mobile device  10 . At Step  124 , a display is made on the hand-held mobile device  10  that the thermostat (as named previously in step  110 ) has been successfully added. 
         [0029]    At Step  125 , the application (app)  210 ,  401  on the mobile device  10  is enabled. Enablement allows for control of the thermostat  210 ,  401  to begin via the mobile device  10 . Step  125  is the final step that completes the code input and set-up between the mobile device  10  and the thermostat  210 ,  401 . It is noted that during the code input and set-up process, there is no requirement for the user to make any code inputs to the thermostat  210 ,  401  itself or to interact with the display screen on the thermostat itself. The present invention allows for the set-up process solely via the user&#39;s hand-held mobile device  10 . As can be understood, following the set-up, the user can be anywhere in the world and control the thermostat via the mobile device with communications being sent through the standard telephone network to the Cloud and the Cloud server  201  ( FIG. 13 ),  401  ( FIG. 14 ) which can interact with the Wi-Fi network provided by the router  220  ( FIG. 13 ),  407  ( FIG. 14 ) at the user&#39;s residence or commercial facility  401  ( FIG. 14 ). 
         [0030]      FIG. 13  depicts a diagram of the entire system in schematic form. The mobile device  10 , having been set-up and synchronized as describe above communicates via cloud server  201  to a WiFi router  220  located in a home or business. The router  220  communicates with the thermostat  210  via transceiver  215  that includes communication protocol for wireless transmission and receiver functions, such IEEE 802.11. The transceiver communicates with the microprocessor  214  to control the systems connected to the thermostat, such HVAC system control relays  211  that control a furnace or boiler, etc. In an embodiment the microprocessor  214  may be programmed to include wireless mesh communication as disclosed in U.S. Pat. Nos. 8,410,931 and/or 8,233,471 assigned to SIPCO, the total disclosure of such publications are each incorporated by reference herein. 
         [0031]    It is noted that the thermostat  210  may include a touch pad display screen  212 , however the operation and set-up of the above invention does not require the user to input any commands or instructions via the thermostat display  212 . All set-up steps can be accomplished via a remote input device  10  running the communication app and code input system that causes the microprocessor  214  to move to a listen mode when the set-up steps  100  to  126  are followed, as discussed above. In an alternate embodiment, a remote computer (wired or wireless) may be used to set-up or control the thermostat  210  via the internet and a browser by similar set-up screens depicted in  FIGS. 1-11  displayed on a web page according to well know TCP/IP systems. 
         [0032]      FIG. 14  is a schematic view including the components of  FIG. 13  and depicting the links outside of the thermostat  210  ( FIG. 13 ),  401  ( FIG. 14 ). The thermostat links with local router  407  and its Wi-Fi network that links to the internet or first network. External devices such as cloud server  411 , personal computer of repairman or other service providers  412 , external database  413 , the external user&#39;s remote input device, such as a wireless tablet or phone  414  and other wired users  415  may communicate with the local router  407  (through firewall  409 ). The local router  407  can then communicate via Wi-Fi or other protocol such as Zigbee® on a second network with components including the thermostat  401  or other building environment control device that in turn can control HVAC equipment  406  including a furnace heat pump (electric geothermal), electric heat, air conditioning unit, humidifier, dehumidifier, air exchanger, air cleaner or air damper. The thermostat  401  may receive input from wireless sensors  402 ,  403 ,  404  that can provide temperature, humidity and other environmental factors either within the building  401  or outside that may be used by the router to automatically issue commands to the thermostat based on the sensor input or building schedule information. The code input system of the present invention may also be operated via web-site on a computer  408 ,  412  or other means and each of the components of the system  401 ,  402 ,  403 ,  404 .  406  and  407  may have a unique identifier, such as an IP address. The router  407  may have a local cache to store the IP addresses when each device is joined to the network. The second network may require a service set identifier (SSID) as an access parameter or a passcode. 
         [0033]    Numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the claims be interpreted to embrace all such variations and modifications.
