A control system for controlling a heating system having a heat pump and a source of supplemental heat. Simultaneous operation of the heat pump and supplemental heat source is monitored, and when such simultaneous operation occurs for a given portion of a heating cycle, the heat pump will shutdown until the temperature has risen by a predetermined amount or a given interval of time has elapsed. The heat pump is also shutdown if the outside ambient temperature falls below a certain level and is automatically reenabled if the outside ambient exceeds a second level.
