Base - May 2004

The fan is provided with an electromagnetic junction

monitored by the electronic centre pin A39 that activated

the junction remote control switch, to optimise water

cooling.
The electrical fan remote control switch is activated or

deactivated by the centre according to the temperature of:
- the coolant
- over supply air
- the fuel

Engine coolant temperature
Activated at over 96 °C and deactivated at under 84 °C
Over supply air temperature
Activated at over 75 °C and deactivated at under 65 °C
Fuel temperature
Activated at over 20 °C and deactivated at under 10 °C

The function of the system is to automatically or manually

control the temperature required in the cab.
According to the set required temperature the system

controls:
- automatically:

air vent temperature

fan speed (continuous changing)

- manually:

fan speed

compressor on/off

outside air inlet/re-circulation

MAX DEF function (defrosting);

- totally manually (through bowden cables):

distribution of air flows to the air vents.

A special electronic control unit controls automatic system

operation checking the various parameters in order to

provide the comfort required in the cab.

The control unit carries out and sets certain functions to

obtain adaptation of the temperature of the cab to the one

required depending on the requests received and the

temperature conditions detected.
