Condensation Sensor Program
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 condensa-
tion 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.
