ABSTRACT:
A temperature control system for providing an automatic reduction in the temperature of a room or a house during the nighttime hours which requires only the conventional two conductor wiring between the furnace and the thermostat thereby avoiding the necessity of adding to or replacing the existing wiring between the furnace and the thermostat. The system includes a temperature responsive element, a heater near the temperature responsive element for providing supplemental heating of the element, a conventional furnace control, a clock-operated current control for the heater, and a diode steering circuit for directing one portion of an alternating current waveform through the heater current control and the heater, and another portion of the alternating current waveform through the temperature responsive element and the furnace control for providing independent control of the heater and the furnace control. The heater provides supplementary heating of the temperature responsive element during the nighttime hours to establish an apparent room temperature which is higher than the actual room temperature so that the thermostat element will lower the room temperature during the nighttime hours.
