摘要： A method of controlling a heating system including at least a first stage heat pump and a second stage auxiliary heater, and a control that implements the method. The control shuts off the first stage heat pump during cold outside temperatures without the need to directly sense the outside temperature. The method includes selectively turning on the first stage heat pump or the second stage auxiliary heater based upon a measure of the amount of time at least one of the stages was on verses the time neither of the stages was on. This can be implemented with a counter that increases when neither the heat pump nor the auxiliary heater is on, and that decreases when either the heat pump or the auxiliary heater is on.

摘要： A microprocessor based control system monitors and controls a heat pump water heater system and interfaces the water heating system with an external centralized control system. The microprocessor control system includes sensors, safety switches, device interface relays, user interface devices and precanned software to provide versatile monitoring and control over a heat pump type water heating system. The system generally involves a typical heat pump coupled with a domestic water heater, hot water retention tank or other body of water. The control system provides operational control over the heat pump to maintain the hot water stored in the domestic water heater in a predetermined setpoint and controls the use of electric resistance heating elements in the domestic water heater for added heating capacity for quick heat recovery type operation. The control system receives a centralized signal typically from a utility company to disable heat pump water heating operation during peak demand time periods. Control logic is provided to carry out effective liming parameter control, high evaporator temperature control, and defrost/anti-freeze protection control.
