2428102 - E6021 COMPRESSOR ENGAGEMENT - Description
Description
The centre button in the climate control control panel switches on the air cooling and dehumidifying circuit, activating the air conditioning compressor.The above button enables the operation of the air cooling circuit; but the actual switching on of the compressor also depends on the intervention of:
- the fan linear sensor, located in the refrigerant circuit, which stops the air conditioning being switched on if the pressure of the fluid is too low or too high;
- the engine control unit which, according to the engine management logic, excludes the operation of the compressor, for example in the case of high engine temperatures or in the case of high engine loads (sharp acceleration);
- the frost thermostat sensor, near the evaporator, which stops the air conditioning being switched on if the temperature of the evaporator is too low;
