03-AC-5145 THERMOSTAT AND CIRCUIT Abstract of the Disclosure A thermostat adapted to regulate the operation of a heating system and a cooling system in response to the temperature in a space conditioned by the systems. The thermostat has a pair of means selectively movable to respective ones of adjusted positions and adapted for sensing the temperature of the space within a preselected temperature range, respectively. A pair of sets of at least three switches means are associated with temperature sensors and are operable for controlling the operation of the heating system and the cooling system, respectively. At least three anticipation heaters are disposed in heat transfer relation with one of the sensors and are energized in response to the operation of the at least three switches of one of the sets therof for supplying anticipation heat to the sensor only during the operation of the heating system, respectively, the at least three anticipation heaters being connected generally in star circuit relation with each other and respectively connected in series circuit relation with the at least three switches. An electrical circuit for a thermostat is also disclosed.
