Climate System Temperature Too Cold or Too Warm Compared to Panel Setting
If you receive customer reports in the above model vehicles that the interior temperature is either too cold or too warm in relation to the set
temperature, the coding of the sun sensor can be adjusted. The influence of the sun sensor on blower control can be coded via SDS per the below
steps. This adjusts the blower reaction in relation to the level of solar radiation.
1.
Connect SDS and follow the path: Control units -> Air conditioning -> AAC Automatic Air conditioning -> Control unit adaptations -> Read
coding and change if necessary -> This setting should only be changed at the request of the customer -> Evaluation of solar radiation -> Select
from range of 0 to 150%
Note:
With the adjustment set to 0%, the solar sensor will have no influence on the blower reaction. If set to 150% the sensor will have the maximum
effect on blower reaction.
Note:
The setting from the factory is 100% for vehicles with standard glass and 66% for vehicles with IR glass.
Note:
The customer request of resetting cannot be claimed under Warranty.
