PURPOSE:To simplify electric wiring work for a remote place, and facilitate adding an operating part after the work and removing the device to another place, by a method wherein a main operating part is detachably provided in a housing, and sub-operating parts are sequentially relay-connected in series with each other by using the main operating part as a relaying part in wiring so that each of the operating parts can be used independently or alternately. CONSTITUTION:The hot water supplying device is provided outdoors, from which the main operating part 6 is drawn out and is fixed to a predetermined wall surface in a kitchen A. Then, a relaying code 10 is connected by penetrating through a through- hole provided in a wall part. Subsequently, the first sub operating part 11 is fixed to a pedetermined wall surface in a toilet room B, and an electric code 19 is connected by penetrating through a through-hole provided in a wall part. By using the first sub operating box 11 as a relaying part, the second sub operating part 15 provided in a bathroom C is connected. Under this condition, the main operating part 6 is operated, or the first sub-operating part 11 is operated, or a priority change-over switch 17 provided at the second sub-oprating part 15 is changed over to the bathroom C side, and the hot water supplying device can be operated by rotating control knobs 16. |
