PURPOSE:To reduce an operation knob further, by reducing a number of connecting lines of a transmission path and eliminating miswiring at the time of wiring work, in a hot water supply device possessing a remote control part which is capable of making remote control in setting a temperature of supply hot water of the device through a transmission path. CONSTITUTION:A temperature setting part 29 is connected with a connecting line 35 through a plug 27 and connecting terminals 30, 31 or 32, 33 made of a conductive material. A series circuit is formed of the connecting line 35 along with resistance Ro and a thermistor in the inside of a combustion control part 7, and the connecting line 35 is connected with a power source +E and GND. A temperature of a supply hot water can be detected by voltage Eth in the series circuit. As for connecting parts 25, 26 it is well enough only to connect them with the connecting line 35 in a non-polar state. Then in case of use of a shower bath it is well enough only to connect a remote control part 28 with the connecting part 26 provided in a bath room, a temperature is set at user's choice newly by operating a temperature setting part 29. |
