This protection prevents the compressor from working at high discharge pressure when in heating mode and is based on the temperature information of the evaporator unit coil sensor.
- With the equipment running in heating mode, if the temperature on the internal coil sensor reaches 54 ° C, the board switches off the external ventilation motor. This will reduce the suction pressure and, consequently, the discharge pressure too.
- If the temperature, even without external ventilation, continues to rise and reach 60ºC the compressor turns off;
- The compressor will restart when the temperature of the internal coil sensor reaches 56 ° C;
- The external fan will restart when the temperature of the internal coil sensor reaches 45 ° C;
