Your boiler is trying to connect to a remote control accessory that it cannot find or which has lost power.

Technical description: Without Vitocom 100 communication interface
What causes this fault?

The most common reason is a loose or damaged data cable between the module and the boiler, or the internal communication component has lost power and stopped sending a signal.
