Abstract: A heat pump controller for use in a heat exchange system includes a computing device and a user interface coupled to the computing device. The computing device is configured to initiate a defrost cycle based on one of a plurality of user-selectable defrost modes, and the user interface is configured to display the user-selectable defrost modes and receive a user selection corresponding to one of the user-selectable defrost modes.

Abstract: A heat pump controller for use in a heat exchange system includes a first input connector, a second input connector, and a computing device. The first input connector is configured to be coupled to a first sensor for receiving a first signal from the first sensor. The second input connector is configured to be selectively coupled to a second sensor for selectively receiving a second signal from the second sensor. The computing device is configured to initiate a defrost cycle, and is selectively configurable between a plurality of defrost modes including a first defrost mode and a second defrost mode. In the first defrost mode the computing device initiates the defrost cycle based on the first signal received from the first sensor and a period of time. In the second defrost mode, the computing device initiates the defrost cycle based on at least the second signal received from the second sensor.

Abstract: A heat pump controller for use in a heat exchange system including an external heat exchanger, a compressor, a reversing valve, and an internal heat exchanger is provided. The heat pump controller includes a first input connector, a second input connector, an output connector, and a computing device. The first input connector is configured to be coupled to a first sensor for receiving a first signal from the first sensor. The second input connector is configured to be selectively coupled to a second sensor for selectively receiving a second signal from the second sensor. The output connector is configured to be coupled to the reversing valve. The computing device is configured to initiate a defrost cycle. The heat pump controller is configured to operate with at least two types of heat exchange systems.

Abstract: A heat pump controller for use in a heat exchange system including an external heat exchanger, a compressor, a reversing valve, and an internal heat exchanger is provided. The heat pump controller includes a computing device and a user interface coupled to the computing device. The computing device is configured to output an energizing signal to the reversing valve while the heat exchange system is in one of a heating mode or a cooling mode based on one of a plurality of user-selectable reversing valve energizing modes. The user interface is configured to display the user-selectable reversing valve energizing modes, and receive a user selection corresponding to one of the user-selectable reversing valve energizing modes.
