Electric Suction Type Fan Control Module

Function
The control module for the electric suction-type fan (engine/A/C) (N76) receives input information on the coolant temperature and refrigerant pressure.

The control module for the electric suction-type fan (engine/A/C) (N76) compares these values with stored values and increases the speed of the electric suction-type fan (engine/A/C) (M4/3) from 20% for basic ventilation (with A/C compressor ON) up to 100% under the following conditions:

- Refrigerant pressure > 13 bar
- Coolant temperature > 103 °C

The speed is set back to 20% basic ventilation under the following conditions:
- Refrigerant pressure < 12 bar
- Coolant temperature < 100 °c
