If it is not repaired in time, the indoor temperature will gradually decrease. Since the indoor temperature is reduced, a process is required. During this process, the residents It may not be known that the living experience of residents will be affected after the temperature drops to a low temperature state, but in this embodiment, the inlet water flow sensor 4 and the returnwater flow sensor 5 can transmit the flow signal at the first time when the radiator 1 is blocked.
