Mode 2: Calibration Run
The objective of the calibration procedure is to correct the position drift of the servomotors for temperature and air distribution control. During a calibration run
- Both servomotors are driven to their two end positions and the new values stored in the IHKA EEPROM.
- All LED's activated simultaneously.
- Blower streamer bars individually illuminated.
- CA flashes in the central display panel at 0.5 Hz.

IHKA FAULT CODES
There are three possible operating statuses shown in the central display
- CA = Calibration Active
- CC = Calibration Complete
- FF = Fault
