摘要

PURPOSE: To fix the width of one step of a set water level and easily set a desired water level by stepwise setting by hot water supply amount set means the amount of setting of hot water supply to a bath tank and increasing a difference between the amounts of setting of hot water supply for successive steps following an increase of the amount of setting of the hot water supply to the bath tank. CONSTITUTION: The amount of setting of hot water supply is stepwise adjusted by operating a set hot water amount increase button 27 or a set hot water amount decrease button 28. A hot water supply setting display part 29 that exhibits the amount of setting of hot water supply as a water level in a bath tank lights a plurality of lighting parts (a) to (k) from the lower part and lights them up to the upper parts as the amount of setting of hot water supply increases. The lighting part just above the lighting part which lights turns on each time the set hot water amount increase button 27 is pressed one time and the uppermost part among the lighting parts turns off each time the set hot water supply amount decrease button 28 is pressed one time. Herein, a difference between the amounts of successive setting of hot water supply for each pressing of the set hot water supply amount increase button 27 or the set hot water amount decrease button 28 is increased as the set water level is located more above while it is decreased as the same is located more below.
