Abstract
An electronic programmable thermostat having different modes of fan operation, including an automatic mode, a time mode, and a continuous mode, preferably includes a temporary fan-on mode for selecting a predetermined period of time for enabling operation of a climate control system including an air circulating fan. The period of time for operation of the temporary fan on mode is selected from a plurality of predetermined periods of time. The temporary mode of operation preferably can be selected during any other mode of operation and after the expiration of the selected period of time for temporary fan on operation, the thermostat returns to the mode of operation of the fan that it should be in based on a programmed schedule of the thermostat. Selection of a predetermined period of time and activation of the temporary mode results in operation of the air circulating fan for that selected period of time.
