Recirculated-air flap positioning motor -V113-
   
Display zoneMeaningExplanatory Notes
1Actual feedback value for the potentiometer in the positioning motor for recirculated-air flap -G143- (in the positioning motor for recirculated-air flap -V113-
l  Display value greater than “5” and less than “250”
l  Maximum permissible deviation: 3 units from the specified feedback value (in the range greater than 50 but less than 200)
2Target feedback value for the potentiometer in the recirculated-air flap positioning motor -G143- (calculated by the operating and display unit for air conditioner/Climatronic -E87-)
l  Display range 5 ... 250
3Value for the potentiometer in the recirculated-air flap positioning motor -G143- ascertained during “basic setting” and saved in the operating and display unit for air conditioner/Climatronic -E87- with the positioning motor in the “very bottom” position (recirculated-air mode)
l  Display value greater than “5” and less than “50”
4Value for the potentiometer in the recirculated-air flap positioning motor -G143- ascertained during “basic setting” and saved in the operating and display unit for air conditioner/Climatronic -E87- with the positioning motor in the “very top” position (air flow mode)
l  Display value greater than “200” and less than “250”

  Note
t  The “air flow mode” position is only obtained with a stationary vehicle during final control diagnosis.
t  In fresh-air mode, a feedback value between “135” and “145” is displayed in display zones “1” and “2”.
t  The following air conditioner operating statuses are possible via the levers fitted on the flaps depending on the positioning motor setting:
t  - Fresh-air flap closed and recirculated-air flap open = Recirculated-air mode
t  - Fresh-air flap open and recirculated-air flap closed = Fresh-air mode (feedback value in display zones “1” and “ 2” between “135” and “145”).
t  - Recirculated-air flap closed and fresh-air flap closed = Air flow mode
t  The position of the fresh-air flap is program-controlled in air flow mode. Depending on vehicle speed, the fresh-air blower speed, the selected and actual temperature readings and the selected operating and display unit for air conditioner/Climatronic -E87- mode, the flap is closed from a speed of approx. 80 km/h. However, the fresh-air flap is not completely closed in air flow mode (it always remains open far enough to maintain the necessary air throughput).
