ABSTRACT:
An electronic programmable thermostat having a program set made up of a plurality of program start times and program temperature values for a daily time period which can be automatically vacated upon initiation by the thermostat user. The user may initiate a temporary reset of the program time/temperature values whereby a microprocessor sets a new temperature value corresponding to a comfort temperature value obtained from one of the program temperature values. Preferably, the system automatically sets a temperature value equal to the highest temperature value of the program set temperatures, when in a heating mode, or the lowest temperature value when in a cooling mode. The system maintains such reset values until the beginning of one of the program start times depending upon when the reset feature was selected by the user.
