Gas hot water heaters have recently come into widespread use as hot water supply and heating equipment for residential homes. Gas hot water heaters supply hot water generated inside the water heater to water supply equipment such as hot water faucets and showers by switching pipes, or pass the water through circulation pipes to the radiator of heating equipment, bath heaters, etc. It is something. A controller is provided as a switch box for selecting hot water supply, heating, and switching the temperature of supplied hot water, and this controller is often connected to a cable drawn out from the water heater. Usually, the water heater body is installed outside the building, and the controller is brought indoors and attached to a pillar or the like.

By the way, when installing the gas hot water heater mentioned above during construction of a building, there is no particular problem as it is only necessary to open a hole in the wall of the building where the installation is planned for the controller cable to be drawn in. When installing a gas hot water heater in a building, additional holes must be drilled into the wall of the building. It is not easy to drill holes in walls where interior and exterior work has been completed, and in concrete buildings, especially apartment complexes, it is difficult to run cables through the walls due to sharing issues. Another problem with the conventional device is that since the controller is simply a switch operation panel, it is impossible to confirm whether the switch operation is actually implemented in the outdoor water heater.
