Abstract
A control for the indoor air circulating fan of a heat pump when the heat pump is operating in the heating mode. After the compressor starts, the control delays the operation of the indoor fan if the temperature is below a predetermined reference temperature. The delay time increases as the outdoor temperature decreases.
