Error messages
The control unit continuously monitors the temperature sensor for short circuits and interruptions.
However only the sensors which are activated are monitored. That means:
If only IR radiators are connected then only the cabin temperature sensor is monitored:
If only IR heating foils are connected then both sensors are monitored.
If both IR radiators and IR heating foils are connected then both sensors are monitored.
The error messages appear as follows:
12:00
20°C
SENSOR - BREAK 1
12:00
20°C
SENSOR - SHORT 1
12:00
20°C
SENSOR - BREAK 2
12:00
20°C
SENSOR - SHORT 2
= Interruption in the room sensor circuit
= Short circuit in the room sensor circuit
= Interruption in the foil sensor circuit
= Short circuit in the foil sensor circuit
If one of these messages appears contact your authorized dealer to have the system checked by
a specialist.
At room temperature (approx. 20° C) the KTY sensor shall have a resistance of approx. 2 kΩ.
