Control Module HVAC: Description and Operation

User Programming
The ACC control module can be programmed by the user. This means that manual settings can be programmed so that the ACC control module selects them after starting. Other functions that have not been selected manually when programming will be controlled automatically.

This means that the electrically heated rear window and recirculation can only be programmed for the opposite of what the auto program selected when programming was carried out.

Programming is carried out by pressing FAN UP and ECON simultaneously. Cancelling the programming is done by pressing FLOOR and ELECTRICALLY HEATED REAR WINDOW simultaneously. In both cases the selection is acknowledged by flashing of the background lighting.

Programmed settings are activated only when the ignition has been switched OFF for more than four minutes.

User programming of the recirculation motor and electrically heated rear window can also be carried out by means of an ISAT.
