Heat pump control

A control is provided that includes a sensor that provides an output indicative of a sensed temperature of a condenser coil of the heat pump, and a controller for controlling activation of at least a compressor of the heat pump. The controller is configured to compare the output of the sensor to a r...

More Information
Summary:A control is provided that includes a sensor that provides an output indicative of a sensed temperature of a condenser coil of the heat pump, and a controller for controlling activation of at least a compressor of the heat pump. The controller is configured to compare the output of the sensor to a representation of sensed ambient temperature to determine whether the reversing valve is in heat mode where the sensed ambient temperature exceeds the sensed temperature of the condenser coil, or in cool mode where the sensed ambient temperature is less than the sensed temperature of the condenser coil. The controller is further configured to deactivate at least the compressor of the heat pump when the reversing valve is determined to be in a mode that is inconsistent with the heat pump's heating operation or cooling operation.
