Auxiliary Fan Control Module

The auxiliary fan control module (N65/1) switches on and off the auxiliary fan (M4).

The pushbutton control module transfers the input information on the coolant temperature and/or refrigerant pressure to the auxiliary fan control module.

The auxiliary fan control module compares these values with stored values and switches the auxiliary fans (M4m1/M4m2) ON or OFF according to the conditions listed in the table below.
