Abstract
A variable speed control system is provided for use with a heat pump heating/cooling system having a variable speed compressor. The control system includes a remote transceiver, a second transceiver to communicate with the first transceiver, and an AC power module to communicate with the second transceiver. The AC power module further includes multiple current limiting devices and multiple temperature sensors and varies the output of the variable speed compressor by comparing the readings from the temperature sensors to a pre-determined temperature setting.
Claims9
A variable speed control system for a heat pump, wherein the heat pump is mounted to a recreational vehicle, the variable speed control system comprising:
- a first transceiver;
- a second transceiver communicating with the first transceiver;
- a power module board communicating with the second transceiver, and receiving AC power from a power source external to the recreational vehicle;
- a first current limiting device operatively attached to the power module board;
- a second current limiting device operatively attached to the power module board, and receiving an input from a circuit amps selector that is external to the recreational vehicle and that is associated with the power source external to the recreational vehicle and that provides a selected ampacity from a plurality of ampacities as the input;
- and,
- a variable speed compressor;
- wherein the first current limiting device identifies the maximum allowable current available that the control system can deliver to the heat pump, and,
- wherein the second current limiting device reads the selected ampacity from the input and further limits the current that the control system can deliver to the heat pump according to the input from the circuit amps selector that is external to the recreational vehicle and that is associated with the power source external to the recreational vehicle.
