PURPOSE:To improve a safety characteristic and a reliability by a method wherein a displaying means is provided for displaying that an operating switch for a first controller is manually operated when a second controller is changed over to a second preferential state. CONSTITUTION:A micro-computer 8 may preferentially read a second set feeding out hot water temperature than a first set feeding-out hot water temperature when a changing-over switch 73 is changed over to a second preferential state, a changeover lamp 64 is turned off and then a changing-over lamp 74 is lit. The micro-computer 8 has a changing function 81 for turning on an operation switch 63 when it is changed over to the second preference state with a changing-over switch 73 and then changing the second preference state to the first preference state when the first setting switch 61 is manually operated during a predetermined time. The micro-computer 8 turns on the operation switch 63 when it is changed over to the second preference state with the changing-over switch 73 and illuminates the changing-over lamps 64 and 74 during a predetermined period of time or until the first setting switch 61 is manually operated. With such an arrangement, for example, it is possible to promote an attention to the user.
