Abstract
A method of operating a heat pump system is provided, the heat pump system having at least a controller and configured to operate at least two defrost cycles. The method comprises receiving, at the controller, weather data for a defined geographic area proximate to an installed location of the heat pump system; and selecting, based on said weather data, one of the at least two defrost cycles.
Claims32
A controller for a heat pump system, the heat pump system configured to operate at least two defrost cycles, the controller configured to:
- receive weather data for a defined geographic area proximate to an installed location of the heat pump system;
- and
- select, based on said weather data, one of the at least two defrost cycles.
A method of operating a heat pump system, the heat pump system having at least a controller and configured to operate at least two defrost cycles, the method comprising:
- receiving, at said controller, weather data for a defined geographic area proximate to an installed location of the heat pump system;
- and
- selecting, based on said weather data, one of the at least two defrost cycles.
A heat pump system, comprising:
- an evaporating heat exchanger coil;
- an outdoor controller configured to initiate at least two defrost cycles;
- and
- an indoor controller, the indoor controller configured to:
- receive weather data for a defined geographic area proximate to an installed location of the heat pump system;
- select, based on said weather data, one of the at least two defrost cycles;
- and
- communicate the selected defrost cycle to the outdoor controller.
A controller for a heat pump system, the heat pump system configured to operate at least two weather modes, the controller configured to:
- receive weather data for a defined geographic area proximate to an installed location of the heat pump system;
- and
- select, based on said weather data, one of the at least two weather modes.
A method of operating a heat pump system, the heat pump system having at least one controller, the method comprising:
- configuring the heat pump system to operate in a severe weather mode and a non-severe weather mode;
- receiving, at the controller, weather data for a defined geographic area proximate to an installed location of the heat pump system;
- determining, based on said weather data, that severe weather conditions are present;
- and
- selecting the severe weather mode.
