## Title
Programmable thermostat for a room

## Abstract

A programmable room thermostat adjusts heating and cooling distribution based on one or more pre-selected temperatures, also controls appliances such as entertainment systems and lights, and may be powered by replaceable batteries or household current. The room thermostat monitors the air temperature in the room, which is defined as a zone, and determines whether heating or cooling is needed. Programmable settings for the room thermostat accommodate 24-hour and seven-day cycles, and are capable of applying the user's preferences based on the time of day and the day of the week. When the room reaches the desired temperature, the room thermostat signals a central thermostat to close the damper. The settings of each room thermostat in the home or office may be controlled and adjusted via the user's smartphone or other mobile electronic device.

BACKGROUND OF THE INVENTION
The invention relates generally to energy conservation equipment, and in particular to a programmable room thermostat. The Internet and SMS texting, coupled with the development of computers that are small, inexpensive, and powerful, have opened many possibilities for both communication and automation. Any accessory which can help us conserve energy and make our lives easier can operate automatically and be controlled from a distance. Several inventions have been developed that will automate the temperature control and electric appliances of a home or office, but each has proven less than satisfactory in its own way. In particular, such devices fail to individually control the temperature and appliances in each room to correspond with the schedules and activities of its occupants. A programmable room thermostat, which controls heating and cooling in an individual room as well as activating and deactivating its appliances, and may itself be controlled by a user via a mobile electronic device, would resolve this problem.
SUMMARY OF THE INVENTION
Accordingly, the invention is directed to a programmable room thermostat. The room thermostat adjusts heating and cooling distribution based on one or more pre-selected temperatures, also controls electronic devices such as appliances, entertainment systems and lights. The room thermostat may be powered by replaceable batteries or household current. The room thermostat monitors the air temperature in the room, which is defined as a zone, and determines whether heating or cooling is needed. Programmable settings for the room thermostat accommodate 24-hour and seven-day cycles, and are capable of applying the user's preferences based on the time of day and the day of the week. When the room reaches the desired temperature, the room thermostat signals a central thermostat to close the electronically controlled vent. The settings of each room thermostat in the home or office may be controlled and adjusted via the user's smartphone or other mobile electronic device.
Additional features and advantages of the invention will be set forth in the description which follows, and will be apparent from the description, or may be learned by practice of the invention. The foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the invention in more detail, the invention is directed to a programmable room thermostat 10A. The room thermostat 10A adjusts heating and cooling distribution based on one or more pre-selected temperatures, also controls electronic devices such as appliances, entertainment systems, and lights, and may be powered by replaceable batteries or household current. The room thermostat 10A monitors the air temperature in the room, which is defined as a zone 21, and determines whether heating or cooling is needed. Programmable settings for the room thermostat 10A accommodate 24-hour and seven-day cycles, and are capable of applying the user's preferences based on the time of day and the day of the week. When the room reaches the desired temperature, the room thermostat 10A signals a central thermostat 10 to close the electronically controllable vent 20. The settings of each room thermostat 10A in the home or office may be controlled and adjusted via the user's smartphone or other mobile electronic device 40.
The first exemplary embodiment provides a plurality of room thermostats 10A which may be powered by replaceable batteries or household current. The front surface of each room thermostat 10A comprises a visual display 11 with touchscreen capability, including a digital 10-key keypad for setting preferred temperatures. Five tabs are visible across the lower edge of the visual display 11: the main tab 13, the settings tab 14, the schedule tab 15, the zones tab 16, and the vents tab 17. Tapping on each tab opens a corresponding screen on the visual display 11.
The main screen, which is accessed via the main tab 13, displays an outside temperature display 18, and an outside humidity display 19, with data provided by sensors located on the edges of the room thermostat 10A. The settings screen, which is accessed via the settings tab 14, provides a schedule for the activation and deactivation of the various electronic devices such as appliances and fixtures in the zone 21. Electronic devices may be lights, a refrigerator, or a home entertainment system.
The schedule screen, which is accessed via the schedule tab 15, provides a schedule for the control of the air temperature in the zone 21. The default settings of the schedule provide four periods in each 24-hour day, separated by four thresholds, which are identified as “Wake,” “Leave,” “Return,” and “Sleep.” More or fewer periods and thresholds, as well as different titles for the threshold events such as “Work” or “Walk Dog,” are contemplated and may be customized by the user as desired. Each of the periods corresponds to a desired air temperature in the zone 21 for that period.
The zones screen, which is accessed via the zones tab 16, provides a list of all the zones 21 in the home or office, with default titles such as “Kitchen” and “Bedroom 1” which may be customized by the user as desired. The current temperature and humidity of each zone 21 are also provided on the list. The vents screen, which is accessed via the vents tab 17, individually controls the dampers in floor vents 20, wall vents, baseboard registers, and ceiling vents in the zone 21, via servomotors, which may be powered by batteries or household current.
The central thermostat 10 operates in much the same manner as a room thermostat 10A, with a larger visual display 11. In addition to all of the functions provided by the room thermostats 10A, the central thermostat 10 provides an on-screen digital keyboard for changing the names of zones 21 and threshold events. The central thermostat 10 may also be synchronized with other devices, such as a remote starter for a vehicle, a home security system, or electric door locks.
Electronic components of the system preferably include an internal antenna, a transmitter and a receiver in each room thermostat 10A and in the central thermostat 10 which employ WiFiTM, BluetoothTM or another medium-range wireless communications protocols. Corresponding receivers and internal antennas are provided in the vents to control the servomotors. The room thermostats 10A and the central thermostat 10 also provide a microprocessor, a memory device, and a computer program to operate the system. A mobile application is available to be downloaded to the user's smartphone, tablet, or other mobile electronic device 40 for operation of the system.
To use the first exemplary embodiment, the user downloads the mobile application to the user's mobile electronic device 40 and synchronizes the central thermostat 10 with the mobile electronic device 40. The user may then change the default settings for each zone 21 as desired.
The central thermostat 10, the room thermostats 10A, the floor vents 20, the wall vents, the ceiling vents, and the baseboard vents are preferably manufactured from rigid, durable materials, such as steel, aluminum alloy, or plastic. The central thermostat visual displays 11, the room thermostat visual display 11A, and the mobile electronic device visual display 41 are preferably manufactured from a rigid, durable material which is transparent, such as plastic or acrylic polymer. The antennas, the microprocessors, the memory devices, and the servomotors are preferably manufactured from rigid, durable materials such as steel and aluminum alloy. Components, component sizes, and materials listed above are preferable, but artisans will recognize that alternate components and materials could be selected without altering the scope of the invention.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is presently considered to be the best mode thereof, those of ordinary skill in the art will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should, therefore, not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
