ABSTRACT:
A control circuit for a combination furnace and heat pump wherein a temperature dependent relay is connected to a thermostat such that the heat pump is operated to supply heat to an enclosure when the outdoor temperature is above a predetermined level and the furnace is operated to supply heat to the enclosure when the outdoor temperature is below a predetermined level. To defrost the outdoor coil of the heat pump the furnace is operated to supply heat to the indoor coil of the heat pump and a reversing valve relay is energized whereby the heat pump is operated in a reverse direction to supply heat to the outdoor coil for defrost.
