3309920 - E6020 AIR CONDITIONING - Description
Description
An automatic system manages the climate control in the passenger
compartment, 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;
- air distribution;
- activation of the compressor (air refrigeration circuit);
- activation of air recirculation.
The control unit sets the above parameters
in order to adjust passenger compartment temperature to the required
level.The control unit supplies information on
interior and exterior temperature via special sensors. After processing
the information, it adjusts the passenger compartment air intake speed
by means of the fan motor and the air temperature by a mxer actuator.
It also controls interior air recirculation via a specific actuator.
When required, the ECU automatically activates
the cooling circuit and dehumidifies the air by operating the air
conditioner compressor. (
See E6021 COMPRESSOR ENGAGEMENT
).
In addition to the climate control commands
described above, the climate control system also comprises the solar
radiation sensor located in the middle at the base of the windscreen;
this sensor enables you to foresee an increase in temperature in
the interior compartment caused by heat from solar radiation, and
consequently appropriate strategies are adopted to improve climatic
comfort in the car.

The control unit supply lines are protected
by a fuse in the junction unit.The fan supply line is protected by a special
maxifuse.The system will only operate when the ignition
is turned to MAR.
