3234633 - E6020 AIR CONDITIONING - Description
Description
An automatic system manages passenger compartment climate control,
i.e. temperature and ventilation with recirculation and air flow
orientation.A dedicated control unit manages
system operation by controlling:
- air temperature at outlets;
- fan speed;
- compressor activation (air cooling circuit);
- air recirculation activation;
- "rapid demisting" function;
The control unit sets the above parameters
in order to adjust passenger compartment temperature to the required
level. The system controls are located outside the control unit
housing.The control unit supplies information on
interior and exterior temperature via special sensors.After processing the information, it adjusts
passenger compartment air intake speed by means of the fan motor
and air temperature by means of a mixer actuator. It also controls
interior air recirculation via a dedicated actuator.
When required, the ECU automatically activates
the cooling circuit and dehumidifies the air by operating the air
conditioner compressor. (

supplies controlled by the ignition.The fan supply lines are protected by a
special maxifuse.The system will only operate when the ignition
is turned ON.
