ABSTRACT:
A dual stage thermostat for an electrical space heating system in which there are two microswitches connected in parallel and operated by a common bimetallic strip. The first switch when closed connects a heating element to a power supply through a diode which reduces by half the power applied to the element. The second switch when closed connects the heating element directly to the power supply. The temperature at which the second switch opens is set about 1.5.degree. F. lower than that at which the first switch opens. Thus, as the room temperature approaches the desired temperature, the heater element is switched from full to half power, producing less temperature overshoot and saving energy. The thermostat may be used with any standard two wire heater.
