Alternatively, if the place where the controller device 3 is located is known and the radio wave condition at that place is poor and wireless communication becomes unstable, the controller device 3 is taken to the place where the radio wave condition is good. Even if it is not brought, a desired operation start operation or operation stop operation can be performed by operating the operation unit 21 of the communication relay device 2. As described above, inconveniences that may occur due to portability are eliminated, and the operation of the heat source device 1 can be performed quickly and reliably. In particular, when it is desired to stop the operation urgently, the operation stop operation can be quickly performed using the operation unit 21 of the communication relay device 2 without searching for the location of the operation device 3. As a result, it is possible to ensure the certainty and convenience of the driving operation in terms of safety while enjoying the convenience due to the portability of the operating device 3.

  Further, when the driving operation performed using the operation unit 31 of the controller device 3 is an OFF operation for stopping the driving operation, if the OFF operation command is output, an OFF operation command is sent to the communication relay device 2. Therefore, the communication relay device 2 can receive the signal more reliably. Thereby, even in an indoor environment where the radio wave condition becomes unstable or stable with time, the operation of the heat source device 1 can be reliably stopped using the operation device 3.

  In addition, although the operation switch, the bath automatic switch, the reheating switch, and the call switch are shown as the operation unit 21 provided for the communication relay device 2, at least the operation switch may be provided as the operation unit. Thus, when the hot water supply operation of the heat source device 1 is to be stopped urgently, that is, when the combustion operation is to be stopped urgently, the operation can be stopped by turning off the operation switch. Can be realized.
