Condensation Sensor Function

The following conditions must be satisfied for the condensation sensor to operate:

• The engine must be running
• The IHKA must be in automatic mode

The IHKA control unit evaluates the condensation sensor signal (humidity). If condensation on the windscreen is imminent, the following measures are initiated in sequence to prevent condensation from forming:

• Open defrost flaps further
• Switch from air-recirculation/AUC/automatic air-recirculation mode to partial fresh-air mode
• Switch from partially fresh air in air-recirculation/AUC/automatic air-recirculation mode to fresh air
• Increase blower air volume
• Reduce air volume for the footwell
• Increase desired temperature value

If one measure proves to be ineffective, the next measure is initiated.

Once successful, the measures previously performed are reversed step-by-step in reverse order.
