3234649 - E6020 AIR CONDITIONING - Description (Manual Air Conditioning)
Description
The climate control system is the type where
the temperature and ventilation with recirculation are manually
controlled. The user can select the desired temperature within the
limitations of the system.The climate control system controls
the temperature by heating or cooling the air introduced into the
passenger compartment until the desired comfort level is achieved.
The following parameters/functions are adjusted through manual operation:
- Requested temperature;
- Fan speed;
- Distribution direction;
- Compressor engagement;
- Defrosting/demising function;
- Recirculation.
The entire system can be switched OFF manually,
completely deactivating the air conditioning system, using the centre
knob (except for the recirculation and heated rear windscreen),
insulating the passenger compartment from the outside ambient.
The MAX-DEF function makes it possible to
group together a collection of actions which allow both the windscreen
and the rearscreen to be demisted quickly
See E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING
.
Depending on the commands received, the
control unit sets the passenger compartment air intake speed by
means of the fan motor and the air temperature by a mixer actuator;
It also controls flow distribution via another actuator and - lastly
- the interior/exterior air recirculation function via a final actuator.
When required, the ECU automatically activates
the cooling circuit and dehumidifies the air by operating the air
conditioner compressor
