うになっている。The fan convector 1 can also be operated by a remote controller. For example, when the room temperature, the operating time, etc. are set, a signal regarding the start of operation is sent from the indoor side control section 7 to the outdoor side control section 12. Then, the outdoor control unit 12 controls the hot water boiler 7, the circulation pump 9 and the like to control the fan convector 1.
The hot water in the cis tank 9 is circulated in the heat exchanger 3 on the side.
When the hot water temperature detected by the temperature sensor 6 reaches a predetermined value, the indoor-side control unit 7 starts the operation of the blower 4 and sends hot air into the room. Further, when the room temperature detected by the temperature sensor 5 exceeds a set value, the operation of the blower 4 is stopped, and when the room temperature is below a certain value, the operation of the blower 4 is restarted. The information on the operation stop and the operation start of the blower 4 is transmitted to the outdoor control unit 12, but the outdoor control unit 12 causes the blower 4 to operate.
During operation, the hot water boiler 8 is controlled so that the hot water temperature becomes, for example, 85 ° C., and the hot water boiler 8 is controlled so that the hot water temperature becomes, for example, 65 ° C. when the blower 4 is stopped. .

The indoor control unit 6 determines in step ST1 whether or not the fan convector 1 is in operation, and if it is in operation, in step ST2 cold air blowout prevention (when the operation starts, the temperature of the heat exchanger 3 reaches a predetermined value). Control for delaying the start of operation of the blower 4 until it reaches), and when the prevention of blowout of cold air is released, the control operation at room temperature starts in step ST3. At step ST4, room temperature RT is set temperature TS +
It is determined whether or not the temperature exceeds 2.8 ° C., and if it exceeds, the blower 4 is stopped in step ST5, and step ST6
Then, information regarding the stop of the blower 4 is transmitted to the outdoor side control unit 12.
