Why is my Vaillant VR 50 command not confirmed?
- KKimberly VegaJul 25, 2025
If the Vaillant Thermostat command is not confirmed, it is due to radio interference. This could be because the transceiver cannot be reached, the transceiver cannot implement the command (possibly due to load failure or mechanical blockage), or the transceiver is defective. When an incorrect transmission occurs, the signal LED will light up red.
