Technical 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
Ensure at least one or two radiators have their valves turned fully open to allow heat to circulate.Check that the pump is running and not stuck.Wait for the boiler to cool down naturally; it should restart automatically once the temperature drops.
