2751618 - E6021 COMPRESSOR ENGAGEMENT - Description (Smart gearbox)
Description
A special 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, depending on the engine management logic, excludes the operation of the compressor; for example, in the case of high engine temperatures or high engine load (sudden acceleration);
- information coming from the anti-frost thermostat on whether there is condensation on the air conditioning pipes (for versions with manual air conditioner);
- information coming from the climate control system (for versions with automatic air conditioner).
