Is output from the control unit 32 to the control means 47 of the operation unit control device 48. When a signal from the control unit 7 of the heating boiler 8 is inputted to the control unit control unit 48 (S1), the identification circuit 54 of the control means 47 first determines whether the control unit 47 is equipped with an external circuit. The fan convector 31 is connected to the power supply 29 or, for example, when the external power supply 29 is connected.
The connection signal output from the power supply unit 30 in the
Check if it is entered in 7. (S2) This is because when the self-mounted device is the boiler remote controller 14, the boiler remote controller 14 usually does not need the external power source 29 such as a commercial power source, and is not connected to the external power source 29. On the other hand, when the device on which the vehicle is mounted is the hot water room heater type fan con vector 31, the fan con vector 31 is, for example, the fan con vector 3
1 requires a power supply for driving the blower fan 46 therein, so that the external power supply 29, usually 100

When the identification circuit 54 is not connected to the external power supply 29, the identification circuit 54 is connected to the room temperature sensor 33 such as a room thermistor. It is determined whether there is a power supply 34 for the room temperature sensor, for example, whether there is an AD input of the room thermistor in the microcomputer port. (S5) This is because the boiler remote controller 14 does not have a function of detecting the room temperature and controlling the heating operation. Therefore, there is no room temperature sensor 33 and the power supply 34 for the room temperature sensor.
The fan control vector 31 is provided with a room temperature sensor 33 for detecting a room temperature in order to perform a heating operation so that the room temperature becomes the set room temperature by changing the intensity of the hot air to be blown out. Is the power supply 3 for the room temperature sensor
The power supply 34 for the room temperature sensor is stored even if the fan convector 31 is not connected to the external power supply 29 such as a commercial power supply. When the power supply 34 for the room temperature sensor is included in the identification circuit 54, for example, the microcomputer of the control unit 32 of the fan convector 31 connected to the operation unit control device 48 If there is an AD input of the room thermistor to the port, it is determined that the device in which it is mounted is the fan control vector 31 although it is not connected to the external power supply 29 such as a commercial power supply (S3). The operation unit control device 48 functions as the operation control device 44 of the fan convector 31, and performs operation / display control relating to the boiler operation and operation / display control relating to the air heating operation.
And display control.

The operation unit control device 48 is connected to the boiler remote controller 14.
(S7) to turn on / off the power of the heating boiler 8, start and stop the boiler operation of the heating boiler 8, display the set temperature of the circulating hot water, and the heating boiler. Only the operation and display control relating to the boiler operation, such as the setting and display of the time of the timer operation of 8 and the display of the operating state and error of the heating boiler, etc., are performed. As a result, the control unit controller 48 automatically determines whether the control unit 48 is mounted on the boiler remote controller 14 or the hot water room heater type fan convector 31. 14 operation control device 25 or fan control vector 3
1 as the operation control device 44, the operation control device 25 of the boiler remote controller 14 and the fan control vector 31
And the operation control device 44 can be used as common components, and the cost can be reduced as compared with the case where each of the operation control devices 44 is a dedicated substrate. As described above, the present invention provides an operation unit having an operation / display control function relating to a boiler operation of a heating boiler and an operation / display control function relating to a hot air heating operation of a hot water heating apparatus.
