Remote control thermostat

Claim 1

An apparatus for remotely controlling the temperature of a structure, consisting of: a base unit, said base unit having a means for sensing the local temperature within a room of said structure and comparing it to a user selected temperature input from either a keypad located on said base unit or via a radio frequency signal from a remote control unit and adjusting said local temperature to said temperature input; and at least one remote control unit, said remote control unit having a temperature sensor for sensing the local temperature, a keypad having a numeric keypad and numerous keys with specific functions, a microprocessor controller, a display, a light, and a radio frequency transceiver for transmitting a temperature input entered by a user via said keypad to said base unit, wherein said base unit can receive an instructional RF signal from any remote control unit utilizing the same carrier frequency.

Claim 2

An apparatus for remotely controlling the temperature of a structure, consisting of: a base unit, said base unit having a means for sensing the local temperature within a room of said structure and comparing it to a user selected temperature input from either a keypad located on said base unit or via a radio frequency signal from a remote control unit and adjusting said local temperature to said temperature input; and at least one remote control unit, said remote control unit having a temperature sensor for sensing the local temperature, a keypad having a numeric keypad and numerous keys with specific functions, a microprocessor controller, a display, a light, and a radio frequency transceiver for transmitting a temperature input entered by a user via said keypad to said base unit, wherein said base unit can receive an instructional RF signal from any remote control unit utilizing the same carrier frequency.

Claim 4

An apparatus for remotely controlling the temperature of a structure, consisting of: a base unit, said base unit having a means for sensing the local temperature within a room of said structure and comparing it to a user selected temperature input from either a keypad located on said base unit or via a radio frequency signal from a remote control unit and adjusting said local temperature to said temperature input, wherein said base unit includes an antenna for the transmission of RF signals and can receive an instructional RF signal from any remote control unit utilizing the same carrier frequency; and at least one remote control unit, said remote control unit having a temperature sensor for sensing the local temperature, a keypad having a numeric keypad and numerous keys with specific functions, a microprocessor controller, a display, a light, and a radio frequency transceiver for transmitting a temperature input entered by a user via said keypad to said base unit, wherein said main microprocessor controller further provides three sets of output signals comprising: current ambient temperature, said current ambient temperature signal for displaying on an ambient temperature readout, said ambient temperature readout receiving its signal through a first display driver which is electrically coupled to said main microprocessor controller; current set-point of the Remote Control Thermostat, said current set-point displayed on a set-point temperature readout, said set-point temperature readout receiving its signal through a second display driver which is electrically coupled to said main microprocessor controller; and operational signals from said main microprocessor controller through an output control relay module, said output control relay module capable of providing signals to energize the heating equipment, to energize the cooling equipment and to energize the fan portion of either the heating or cooling equipment.
