Heated Rear Window
The heated rear window is switched on by pressing the heated rear window button in the IHKA controls. The function indicator lamp in the button lights up.
The heated rear window is switched off when the button is pressed again, or automatically when the heating period of 10 or 17 minutes has expired. If the button is pressed again during the heating phase, the afterheating phase (approx. 5 minutes) starts.
- Defrosting phase
When terminal 15 is switched ON, the first time the system is switched on, the time span for the heated rear window is defined as follows:
Ambient temperature down to -15 °C: Heating period: 10 minutes
Ambient temperature below 15 °C: Heating period: 17 minutes
- Pulsing
After the defrosting phase, the heating phase (60 minutes at 1/3 heat output pulsing) begins (on-off cycle: 3 seconds ON, 9 seconds OFF).
The function indicator lamp in the button is off during pulsing.
