4.1 Troubleshooting
CAUTION
Troubleshooting only by professionals!
Troubleshooting requires comprehensive knowledge on the
design and operation of the individual components of the air-
conditioning system and may only be carried out by authorised
professionals trained by Webasto for this purpose.
If malfunctions occur, the system must be switched off.
4.2 Malfunctions that are displayed
The following malfunctions are displayed directly on the digital control element
as a code (e.g. A02). Each time one of these fault codes appears, the system is
stopped for approx. 60 seconds and then a restart is attempted. If a malfunction
occurs more often than 6 times consecutively within 30 minutes, the system is
completely shut down and the fault code is displayed continuously. No further
restarts are attempted and the user should have the fault rectified and then reset
the system by switching it off or by temporarily interrupting the voltage supply to
the system.
