IN-CAR TEMPERATURE SENSOR, FUNCTION - GF83.57-P-2115-02GH

Function

When the blower is running, air is constantly drawn out of the vehicle interior by a suction jet nozzle for the in-
car temperature sensor (B10/4) to measure the temperature when the ignition is. ON .

The in-car temperature sensor (B10/4) records the interior temperature and conveys it to the AAC push-button
control module, where a comparison is made with the setting on the temperature selector. The blend air flap is
repositioned depending on the result of this.

It is connected to the AAC push-button control module via a separate electric cable.

Constant circulation of interior air at the in-car temperature sensor (B10/4) is achieved by this ventilation and
therefore a high level of control accuracy is guaranteed.

In-car
temperature
sensor, task

The in-car temperature sensor (B10/4) with suction jet nozzle records
the interior temperature and conveys this to the AAC push-button
control module. The suction jet nozzle ensures air from the vehicle
interior flows evenly around the in-car temperature sensor (B10/4).

In-car temperature
sensor, location

The in-car temperature sensor (N22b1) is located below in the temperature selector
wheel of the AAC push-button control module.

In-car temperature
sensor, task

The in-car temperature sensor (N22b1) records the in-car temperature and sends it
to the AAC push-button control module (N22).

In-car temperature
sensor, function

The recorded in-car temperature value is compared by the AAC push-button control
module with the setting in the temperature selector wheel whereupon it authorizes a
corresponding adjustment to the blending air flap to be made depending upon the
result.

Center nozzle vent air
temperature sensor,
location

The center nozzle vent air temperature sensor (B10/24) is located to the left of
the air duct's center nozzle below the instrument panel.

Center nozzle vent air
temperature sensor,
task

The center nozzle vent air temperature sensor (B10/24) records the temperature
of the air flowing out of the center nozzle and sends it to the AAC push-button
control module (N22).

Center nozzle vent air
temperature sensor,
function

The vent air's recorded temperature value is compared by the AAC push-button
control module (N22) with the setting in the temperature selector wheel
whereupon it authorizes a corresponding adjustment to the blending air flap to
be made depending upon the result.
