The Viessmann 5549 is a universal push-button panel with feedback, designed for controlling turnouts and signals in model train layouts. It features 8 momentary contacts arranged in 4 groups, with red and green LEDs for status feedback. Important: The feedback function only works with drives that have a mechanical end switch (e.g., Fleischmann, Roco, Märklin, or Viessmann semaphore signals). It is not compatible with digital semaphore signals or older Märklin M/K turnouts.
Installation
Mount the panel using the enclosed screws in a suitable location on your model train layout or diorama. Apply the included decal strip to the housing, ensuring the colors align correctly with the buttons as shown in the diagram.
Connection
You can connect Viessmann semaphore signals directly to the panel. For light signals, a Viessmann universal relay (1 x 4UM, item 5551) is required. Multiple push-button panels can be daisy-chained together using the provided connector element.
Safety and Technical Data
Ensure all wiring is performed while the power supply is switched off. Use only VDE/EN tested model train transformers. The maximum switching current is 2 A, and the maximum switching voltage is 24 V AC/DC. The unit is intended for operation in dry rooms only.

Common problems
Feedback LEDs are not functioning
Ensure the connected drives have a mechanical end switch. The feedback function is not compatible with drives lacking this feature.
Cannot control light signals
Light signals require the use of a Viessmann universal relay 1 x 4UM (item 5551).
Before use
- Verify the transformer is VDE/EN tested
- Ensure power is switched off before mounting or wiring
- Check that drives have mechanical end switches
- Apply decals to the housing for color reference
