Mover and Combi flashing codes

Some of our units have an error code that gives us more detailed information about the cause of the error.

The flashing code is similar to a Morse code. This means short and long flashing characters in an individual sequence (e.g. short, long, ls slls).

This can be used to offer faster help when contacting your dealer, service partner or our service centre.

Mover

On the Mover models, the flashing code consists of eight consecutive characters. This is repeated several times, each time starting anew after a pause of approx. three seconds.

As soon as a fault is indicated on the remote control, the LED (j) on the control unit emits the flashing code.

8 flashing signs

These mover models have the flashing code output:

  • Mover XT models
  • Mover SX
  • Mover SER/TER
  • Mover SR

l

Combi 4/6 (E)

With the Combi Gas connected to the CP classic analogue control unit, the flashing code also provides more precise information on the cause of the fault.

If the control unit reports a malfunction, the cause can be narrowed down more precisely using the flashing code on the heating board.

For Combis manufactured before 06/2018, there are eight flashes of the red LED. For Combis produced later, the number was increased to ten characters.

Combi before 06/2018 – 8 flashing signs
Combi after 06/2018 – 10 flashing signs

You are welcome to send us flashing codes by e-mail as a video or directly name them by telephone.

  1. Hi. I have a Truma mover XT and it has this code: SSLLLLSL (S stands for short and L for long). It is on a Fendt Caravan. I cannot use mover at all and remote indicate some sort of low batt, but there isn’t a low batt anywhere! Thanks

  5. Hi
    Truma XT mover, remote control beeping this: SSSLLLSS
    What does the code mean, and any errors?
    Kind regards

      • Hi Magdalena

        Thanks a lot for the quick response.

        At the moment the caravan is at a local servicepartner, who suggest replacing parts one by one, until the XT mover works again. Starting with the Control unit.
        I hoped for at more precise diagnostic capabilities from their side.
        The control module was replaced in summer 2019 under warranty. So I´m quite disappointed that 3 control modules apparently is needed for normal function in such relatively short period, with this premium mover.

        What is a TIN device? is it the motors? So I can give the local servicepartner a hint 😉

        Regards
        Jan Pedersen

        • Hello Jan,
          The best thing to do is to check the fault memory of the control unit. Our trained service partner can analyse the error with a diagnostic tool.
          TIN devices are the motors that are connected separately to the control unit.

          kind regards

    • Hello Luis,
      unfortunately the code is not assigned. It’s only seven signs. To evaluate the error code, we need eight signs.
