Operating principle
The climate control assembly is enabling outside air penetration in the vehicle climate control
unit.
Climate controls:
A – air temperature adjustment
B – air distribution in the cockpit
C – air quantity adjustment in cockpit
Air temperature adjustment
Control knob (A) is enabling the obtaining of the desired temperature in the cockpit. By
turning to the right the knob (A), the air temperature is increasing.
Air distribution in the cockpit
Air distribution in the cockpit is obtained by means of rotating the knob (B) in the desired
position.
Position
Airflow is directed towards the dashboard air vents.
Position
