Pin 1 of the air conditioning control panel H080 is supplied by the ignition-operated line (INT) protected by fuse F51 of the Body Computer M001 (pin 18 of connector C), and at pin 4 it is supplied by the battery direct line protected by fuse F36 of the Body Computer (pin 13 of connector C).

Also, the control panel H080 is connected, via pin 6, to the air conditioning unit earth C016.

The climate control system control unit H080 manages the air conditioner engagement function from pin 2 by sending the corresponding signal to the Body Computer M001 (pin 42 of connector D), which sends this request to the engine management control unit M010 via the C-CAN.

See E6021

The same signal is sent, depending on the version, either to the conversion socket or to the additional air conditioning system, if present.

See E3094

See E6025

The climate control system control unit H080 receives feedback, at pin 3, that the passenger compartment air fan N085 is turned on.

The speed of the latter is regulated via the fan control H081 which, through the adjustment resistances O030, makes it possible to earth the fan motor through different resistance values, thereby allowing the adjustment of the speed.

The passenger compartment air fan N085 receives a direct battery supply, at pin 2, via the line operated by relay switch T08 (except during starting, "INT/A") and protected by fuse F08 located in the engine compartment junction unit B001.

The passenger compartment air fan control H081 is connected, via pin 1, to the air conditioning unit earth C016.

The climate control system control unit H080 is backlit, via pin 5, when the side lights come on.
