Our Couple Cottage is equipped with a parking heater.
For it to work, the second battery must be charged and the diesel tank must be at least 1/3 full.
The heating is controlled via the Truma display above the sliding door:
- To activate the screen, press the black button briefly. The symbol with a camper and a thermometer will blink.
- Click on the black button to confirm.
- The text "OFF" will appear. Turn the wheel clockwise to select the temperature.
- Once you find the desired temperature, press the button to select.
- The main menu will appear again.
- On the main menu, turn the button to the fan symbol.
- Press the button again and select the mode: ECO, HIGH or BOOST
- Once you have selected the mode, the main menu will appear. Heating should be working now.
- Make sure not to cover the outlets!
Attention: do not block the heating outlets!
The heating consumes a lot of electricity. Please note therefore:
- You can heat self-sufficiently for 1 night.
- If you switch off heavy consumers (such as the refrigerator) overnight, the operating time is extended to 2 nights.
- Danger of switch-off: Check in the evening whether the camping battery has at least 12.3 V (50%) voltage. If the heater does not have enough voltage and you start it several times in vain, the system will lock completely for safety reasons and can only be unlocked by a Truma workshop.

Troubleshooting
If the heating system does not work, check the Truma unit for any error codes that may appear. The most common are:
E653H: The error code appears if the diesel tank of your vehicle is not sufficiently full.
Check the diesel gauge on the dashboard. If the display is in the reserve (red area), you must refuel with diesel before starting the heater.
W412H: The error appears when a window is open. This activates the safety pin to prevent exhaust gases from the heater entering the vehicle. To get the gas flowing again, close the window.
W418H // W411H // W303H // E654H // E566H: The error code appears when the voltage on the camping battery is insufficient.
Check the battery capacity on your on-board display. If the value is below 12.3V, the battery must be charged before starting the heater.
Repeated unsuccessful restarting of the Truma unit can cause a system lockout of your heater.
You found the cause of the error and fixed it? Great! Some errors disappear by themselves.
Others need to be confirmed by navigating to the black button to the exclamation mark (by turning the black button):
Now press the black button to confirm the error. The symbol should now disappear and the heater can be put back into operation using the familiar steps.
Resetting the Truma unit after an error/warning message. Only ONCE!!!
In some cases, it helps to manually reset the Truma. Try this only once – if you repeatedly reset it without eliminating the cause, the entire system can be permanently disabled.
