BoilerFaultCodesTechnical description
Control stop: appears if the measured flow temperature (t1) is higher than the flow temperature set (T flow set). The boiler will start working again automatically once the flow temperature falls below the flow temperature set.
DIY fix possible
Check if your room thermostat or boiler temperature dial is set lower than the current water temperature.Ensure your radiators are not all turned off, which can cause heat to build up inside the unit.Wait for the boiler to cool down; it will restart automatically once the internal temperature drops.
