Technical description
The application of the radioclock module will be recognised automatically
What causes this fault?
This fault occurs when the boiler's main control unit loses its connection to the external radio clock receiver that synchronises the time. The most common reason is a loose wiring connection between the receiver and the boiler, or the internal circuitry of the radio module itself has failed. Because the boiler can no longer confirm the exact time, your programmed heating schedules may become inaccurate.
DIY fix possible
Wait for the boiler to finish its automatic synchronisation processMonitor the display to ensure the code clears and the time updates correctlyRestart the boiler once if the code persists for more than 30 minutes
