とすることができるからである。The reason for transmitting signals for increasing and decreasing the amount of heating from the controller (29) to the controller (30) through the signal lines (31), (32), and (33) is as follows. Conventionally, the combustion lamp (not shown) installed in the indoor unit (2) has been replaced with the outdoor unit (2).
3), the signal lines (31) (32) (
33) and instead connect the heater (30) to the controller (30).
By using it as a signal line for transmitting signals for operation/stop and increase/decrease in heating amount in 9), it becomes unnecessary to install a new signal line, and it becomes unnecessary to increase the capacity of the microcomputer. .

転停止が少なく、温水出口温度の変化を小さくできる。In the air conditioner (1) configured in this way, the controller (
The controller (30) turns on the heating machine (9) in response to a signal from the heater (9).
Since the amount of heating is controlled in eight stages, the number of shutdowns of the heating machine (9) is reduced, and changes in the hot water outlet temperature can be reduced.
このため、室内ユニット（２）の熱交換器（１１）での
放熱量の変化を小きくでき、非常に安定した暖房を行な

を防止することができる。The controller (30) also opens the proportional control valve (24) if the hot water outlet temperature is less than 60°C even if a signal to reduce the heating amount or maintain the heating amount is input from the controller (29). The amount of heating by the heater (9) is increased by controlling the temperature to increase. When the amount of heating by the heater (9) increases, the temperature of the combustion chamber (22) and the heat absorber (10) rises, making it possible to prevent dew condensation in the combustion chamber (22) and the heat absorber (10). can. If dew condensation can be prevented in the combustion chamber (22) and the heat absorber (10), corrosion of the combustion chamber (22) and the heat absorber (10) can be prevented.
