Abstract
Devices and methods for controlling a heat pump system are presented. A method may include identifying, by a first device, a signal received from a second device associated with an outdoor portion of the heat pump system, the signal indicating that the heat pump system is performing a defrost operation; reducing, based on the defrost operation, a speed of a fan associated with an indoor portion of the heat pump system; identifying pressure data received from a pressure sensor during the defrost operation, the pressure data indicative of a suction line pressure of the heat pump system; determining, based on the pressure data, that the suction line pressure is below a threshold pressure, the threshold pressure greater than a low-pressure fault threshold; and increasing the speed of the fan based on the determination that the suction line pressure is below the threshold pressure.
