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.
In a thermostat for controlling the operation of a climate control system including an air-circulating fan, the thermostat providing at least one of the following user-selectable modes of operating the fan:
A thermostat for controlling the operation of a climate control system including an air-circulating fan, the thermostat providing a temporary fan-on mode for selectively operating the air circulating fan only once for a pre-selected period of time in addition to at least one other user-selectable mode of operation selected from:
In a method of controlling a climate control system including an air-circulating fan in which the fan is operated in at least one of an automatic mode wherein the fan is operated based on temperature-related demands of the climate control system, a time mode wherein the fan is operated based on the time of day, and a continuous mode wherein the fan is operated continuously, the improvement comprising the step of selectively operating the fan in a temporary fan-on mode in which the fan operates only once for a preselected period of time.
