DescriptionThe special button ('ice symbol) 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; For more details 2398701Characteristic of working principle5040AIR CONDITIONING CASING AND COMPONENTS . With the compressor switched on, the fan is operated at the first speed by means of a special relay located inside the unit.The fan is supplied by a line protected by a specific fuse and operated by a special relay, in the engine compartment junction unit.The fan is supplied by a line protected by a specific fuse and operated by a special relay, in the engine compartment junction unit.The supply for the controls comes via a line controlled by the ignition and protected by a fuse in the underdashboard control unit.
Functional description Relay T5 of engine compartment junction unit B1 controls the compressor activation circuit The relay power supply passes through the line of dedicated fuse F19 of engine bay junction unit B1 The power supply to the coil of relay T5 arrives from main injection relay T9 and ignition-opeated line (15/54) protected by fuse F18 , both located in engine compartment junction unit B12399345SeeE5050DIESEL ENGINES ELECTRONIC MANAGEMENT .
