摘要：
A control system for controlling a heating system having a heat pump and a source of supplemental heat. The indoor heat exchanger temperature is monitored, such as by a thermocouple or the like, and when the temperature falls below a given threshold level, defrost cycling of the heat pump is initiated. The control system monitors the defrost cycling of the heat pump, and when the heat pump is in its defrost cycle for more than a predetermined portion of a heating cycle, the heat pump will be shut down until the outdoor ambient temperature has risen by a predetermined amount or a given interval of time has elapsed.
