4.2.2 Programmable control panel
The programable control panel can be used with all types of
Dual Top heaters.
The heater is able to identify faults on individual components
and during the operation.
The control panel gives out the fault message.
Rectify the cause of the fault.
To reset the fault, confirm message by pressing OK (if
provided) or switch off the Dual Top for at least 5 seconds.
If serious malfunctions such as overheating or failure to start
reoccur, the heater is locked and can be put back into service
by deleting the failures.
Do this by disconnecting the power supply:
Ensure that the heater/blower is not running (to be
established by the sound of the heater operating).
If necessary wait until the blowers stop running.
Unlocking:
– Switch on programmable control panel and heater and
leave "ON" (control panel in any "ON" operating mode)
– Remove 15 A fuse (red wire, thermo unit)
– Install 15 A fuse (red wire, thermo unit)
Or:
– Switch on heater on control panel
– Message 17 is displayed
– Heater does not react
– Remove 5 A fuse (control panel)
– Remove 15 A fuse (10 A) (red/black wire, PWM module)
– Remove 15 A fuse (red wire, thermo unit)
– Replace 10 A fuse with 15 A
– Install 15 A fuse (red/black wire, PWM module)
– Install 15 A fuse (red/black wire, PWM module)
– Install 5 A fuse (control panel)
– Switch on heater on control panel
Now the heater is reset.
Deleting failures can also be done with the Webasto Thermo
Test PC-Diagnosis.
If a fault occurs, the heater stops. Failure of drainage valve
(message 28 and 29) will not abort heater operation and will
not be shown during heater operation.
