General determinations on actuator motor and flap controls
Continuous positioning of the flaps.
So that the actuator motors do not run continuously in the control range, the following release function is realized in the automatic air conditioning for
each flap.
Release function: Once a position has been set, the specified blower air temperature for example must change sufficiently by the next change for the
release value above or below it to be under- or overshot.
Final values are approached directly (0 %, 100 %).
Anti-fogging function
The anti-fogging function prevents the windshield and side windows fogging after the engine is started, i.e. the moist air is no led to the windows
immediately after starting but into the vehicle's footwell.
Solar roof function (on model 211.0 with code (419) solar module for panoramic roof)
The actuator motors are driven to the following position after 2 minutes and outside temperatures greater 10 °C:
-
center nozzle
100 % open
-
activated charcoal filter flap OFF (fresh air)
After this the comfort AAC control and operating module (N22/7) switches off.
For
-
automatic and manual flap operation
-
With ignition OFF or REST OFF or stationary heater OFF (if fitted) the following sequence applies:
The actuator motors are moved to the following positions 2 minutes after device OFF:
-
footwell flaps open
-
defroster flaps closed
-
recirculated air flap closed
-
The center nozzle and activated charcoal filter stop in the last valid setting
For
Ignition ON:
up to 30 seconds after engine ON
REST ON:
60 seconds starting with the request
Stationary heater ON: 60 seconds starting with the request
the following procedure applies:
-
footwell flaps open
-
defroster flaps closed
-
center nozzle automatically according to specification
-
recirculated air flap immediately operable (including automatic recirculated air)
-
activated charcoal filter flap in stored position
After these times have elapsed, the flap states for the automatic or manual setting apply
Left center air outlet flap actuator motor (M2/12) and right center air outlet flap actuator motor (M2/13)
The left center air outlet flap actuator motors (M2/12) and the right center air outlet flap actuator motors (M2/13) actuate the air flap that controls the air
flow to the center nozzles separately for the left and right.
Depending on the desired air outlet temperature at the center nozzle the left center air outlet flap actuator motor (M2/12) and right center air outlet flap
actuator motor (M2/13) is actuated via the comfort AAC control and operating unit (N22/7) and the AC bus.
Actuation for "DEFROST"
center outlet flaps 0 % (closed).
Actuation with "REST"
according to regulation
Actuation with stationary
heater as per the control (if fitted)
Actuation at "0"
previous position retained
Actuation with ignition OFF,
previous position retained
Automatic air flap control
Depending upon the following variables, the air flap can be opened up to 100 % by the left center air outlet flap actuator motors (M2/12) and right center
air outlet flap actuator motors (M2/13) in line with a defined characteristic.
