- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).

The temperature control enables you to obtain the level of comfort required by mixing the air of the various circuits.

The air distribution control enables you to diffuse the air in the passenger compartment combining several air vents.

The air fl ow control enables you to increase or reduce the speed of the ventilation blower.
