ABSTRACT:
A thermostat adapted for operation in a heating mode and a cooling mode so as to regulate the temperature of a space in which the thermostat may be located. The thermostat has means adjustably movable therein toward selected positions respectively indicative of a selected temperature of the space and operable in the selected positions for sensing the temperature of the space. A pair of means are disposed in heat transfer relation with the sensing means and energized during the heating mode operation and the cooling mode operation of the thermostat for supplying anticipation heat to the sensing means, respectively. Means is disposed in heat transfer relation with the sensing means and energized during the heating mode operation of the thermostat for transferring biasing heat to the sensing means so as to supplement the anticipation heat supplied to the sensing means by one of the supplying means upon the energization thereof during the heating mode operation of the thermostat.
A method of operating a thermostat, an electrical circuit, and a method of heating a temperature sensing means of a thermostat are also disclosed.
