  When the user sets the target hot water volume by the up / down operation of the cross key 40 and the enter key 41 is operated, the remote controller 46 displays the bar graph 52 up to the current time of the day represented on the same scale of the usage amount display screen 51. The target hot water indicator line 58 is superimposed on the bar graph 53 up to the same time the previous day and the bar graph 54 of the accumulated usage of the previous day, and the target hot water amount is displayed numerically.

  In this way, since the usage amount of the previous day and the usage amount up to the current time of the previous day and the current time of the day are displayed in a form that can be listed together with the target hot water amount, From the relationship between the accumulated usage of the previous day and the target hot water volume, and the relationship up to the current time of the day, you can easily check the progress of the usage volume for the target hot water volume for the current day and the usage status of the previous day, and consider the amount you plan to use in the future. This makes it easy to make comparative studies and encourages the use of the day to be reduced, and promotes energy and resource savings through visualization.

  Further, when the return key 42 is operated from the state in which the usage amount display screen 51 in which the target hot water amount is set is displayed, the screen returns to the standby screen 50 that displays the hot water supply set temperature and the like. The usage monitor graph 59 up to the current time of the day is always displayed.

  This usage amount monitor graph 59 displays a target hot water volume index 60, an index 61 less than the target hot water volume (for example, 50%), and an index 62 exceeding the target hot water volume (for example, 120%), assuming that the target hot water volume is 100%. At the same time, the usage amount value of the day is displayed on the origin side of the usage amount monitor graph 59 and the target hot water amount value is displayed on the opposite side of the origin.

  Thus, once the target hot water volume is set, the target hot water volume index line 58 is reflected on the usage volume display screen 51, and the usage volume monitor graph 59 and the target hot water volume index 60 are displayed on the standby screen 50. Therefore, it is possible to constantly compare with the target hot water volume for which the usage amount has been set, and to suppress the usage amount on the day without displaying the usage amount display screen 51. Resources can be promoted.
