The electronically controlled heating and ventilation system of the automatic heater (HEAT [HAU]) achieves the desired interior temperature as rapidly as possible or holds it at a constant value by:
- the heating system heat exchanger heating the air
Heating mode
Heating mode The in-car temperature sensor (N18b1) and the in-car temperature sensor (N70b1) measure the interior temperature.
The outside temperature is additionally detected by the outside temperature display temperature sensor (B14).
The electronic control of the HEAT [HAU] control and operating unit (N18) compares the various readings with the temperature preselected at the temperature selector wheels.
As required, the position of the blend air flaps is either altered or kept constant via the left blend air flap actuator motor (M2/6) and the right blend air flap actuator motor (M2/7).
The in-car temperature sensor (N70b1) is additionally installed in vehicles up to 31.5.02 in the overhead control panel control unit. In vehicles as from 1.6.02 the interior temperature is determined solely by the in-car temperature sensor (N18b1), which is integrated in the HEAT [HAU] control and operating unit (N18).
