ABSTRACT:
A residential-type, heat pump-furnace system with control means for sequencing the activation of the heat pump and furnace operation depending on the heating load. The heat pump remains operational until the air off the furnace has reached some predetermined temperature to prevent an undesirable drop in the temperature of air entering the enclosure. Also, at termination of the defrost cycle, the heat pump will resume operation in the heating mode without the compressor shutting down.
