GF83.10-P-2201GZ Actuator Motors, Component Description
- with CODE (580) Automatic air conditioning
Component Identification
Location
The actuator motors are located in the A/C housing.
Task
General determinations on actuator motor and flap controls
Continuous positioning of the flaps.
The following release function is realized for each flap in the automatic air conditioning to prevent the actuator motors from operating continuously in
the controlled range.
Release function: This is a position which, once set, must change so much up to the next change, e.g. blower stage temperature setting, that the release
value above or below is exceeded or dropped below.
Final values are approached directly (0 %, 100 %).
Anti-fogging function
The anti-fogging function prevents the windshield and side windows from fogging up after starting the engine by blowing the moist air, immediately after
starting, into the vehicle footwell instead of against the windows.
Center outlet flap actuator motor
The center outlet flap actuator motor actuates the air flaps for controlling the air flow to the center nozzle.
The center outlet flap actuator motor is actuated by the AAC control and operating unit (N22) depending on the air outlet temperature desired at the
center nozzle.
Actuation for "Defrost"
Center outlet flap 0 % (closed)
Actuation for "Rest"
according to control
Actuation for "0"
remain in previous condition
Actuation for ignition OFF
remain in previous condition
Automatic air flap control
The air flaps are opened according to a defined characteristic up to 100 % by the center outlet flap actuator motor, depending on the following values:
^
Blending air flap setting
^
Coolant temperature
^
Evaporator temperature
^
Footwell flap position
Air flap control via the center nozzle
