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.

A method of controlling a heating system having a supplemental heat source and a heat pump for supplying heat to an interior space, wherein the heating system includes a thermostat mechanism that activates the heat pump and supplemental heat source in response to ambient temperatures in the interior

A method of controlling a heating system having a supplemental heat source and a heat pump for supplying heat to an interior space, wherein the heating system includes a thermostat mechanism that activates the heat pump and supplemental heat source in response to ambient temperatures in the interior space sensed by the thermostat, said method comprising: sensing when the supplemental heat source is operating during a cyclically recurring time interval, and disabling the heat pump when the supplemental heat source is operating for a predetermined portion of the cyclically recurring time interval. A method of controlling a heating system having a supplemental heat source and a heat pump for supplying heat to an interior space, wherein the heating system includes a thermostat mechanism that activates the heat pump and supplemental heat source in response to ambient temperature sensed by the thermostat, said method comprising: sensing when the supplemental heat source is operating simultaneously with the heat pump during a cyclically recurring time interval, and disabling the heat pump when simultaneous heat pump and supplemental heat source operation occurs for a predetermined portion of the cyclically recurring time interval.
