Meanwhile...Hi first turn of the main power switch in the electrical cabinet off then back in to see if it resets, if not on Truma control panel not the main Vw panel scroll through the screen and try to set the system. Here are the fault code if one is displayed.
Hope you get sorted
Fault code
Cause
Remedy
#17
Summer mode with empty water container
Switch heater off and allow to cool. Fill boiler with water
#18
Warm air temperature exceeded:
- Not all warm air ducts are connected
- Warm air outlets blocked
- Circulated air intake blocked
- Check whether the 4 warm air ducts are connected
- Check the individual outlet openings
- Remove the circulated air intake blockage
#21
Room temperature sensor or cable faulty
Inspect the room temperature sensor cable, replace if faulty
Check the resistance of the room temperature sensor.
15 °C – 16.2 kOhm / 20 °C – 12,6 kOhm / 25 °C – 10.0 kOhm
