A flashing temperature display indicates a connection problem between the ViCare radiator thermostat and the communication module (OneBase heating system or Vitoconnect). It flashes at different speeds:
Flashing = the radio connection is interrupted
Faster flashing = the radio connection is being established
In this case, we recommend checking the quality of the connection and using a ViCare radio repeater if necessary. You can find out more about this here.
As soon as the temperature display lights up continuously, the radio connection is active and stable.
