7.5.2.2 The heat pump operation.
The heat pump's operation mode correlates to whether the compressor is operating. When the
compressor is on and the electric heater is off, the fan motor will operate according to the anti-cold
wind of heat pump. The four-way valve is always on. If T1<Ts-2°F, the compressor is on. If
T1≥Ts+2°F, the compressor will be off. The fan motor also works in correlation to whether the
compressor is in operation. If T2>TE7, the compressor will turn off. When the DAT protection is
triggered, it will prevent the compressor from operating.
