Abstract: A wireless remote temperature sensing and control thermostat system for regulating air ducted air conditioning systems incorporating a normal mode and a remote control mode, including a combination thermostat and radio-frequency receiver unit, a radio-frequency transmitter, and an adjustable register. In the normal mode, a reference temperature is set by the thermostat for the temperature throughout the entire air conditioned structure. In the remote control mode, the local temperature sensing and control functions of the thermostat are disabled and the transmitter unit will take over the temperature sensing at the remote site which, in turn, then will control the thermostat unit. As a result, the users will be able to more accurately control their own personal environment.
