PURPOSE:To clearly indicate the cause of the abnormal state of a full-automatic bathtub by indicator lamps, by distinguishing which safety circuit is actuated by the combination of flashing of indicator lamps and by the difference in the length of flashing time of the lamps. CONSTITUTION:Two kinds of panels are provided. One is a main operation panel 11 which is installed in a kitchen or in a dining-kitchen. Another is a bathtub operation panel 12 to be installed in a bathroom. An operation switch 2 as a power source switch for a control circuit, and a hot water temperature controlling switch which makes the input of a burner variable, are provided in the main operation panel 11. A driving lamp 13 which is lighted when the operation switch is turned ON and a feed hot-water lamp 14 which is lighted when feed hot-water is started are also provided in it. In the bathtub operation panel, a bathtub switch 4 or a bathtub timer is provided. Besides a bathtub lamp 15 which is lighted when a bath is used is provided in it, as wall as a driving lamp 13 and a feed hot-water lamp 14. The operation panels are built so as to distinguish which safety circuit is actuated by the combination of flashing of indicator lamps and the difference in the length of flashing time. With such an arrangement, abnormal state of an appliance can be recognized immediately. To indicate the cause of the abnormal state is very helpful to maintain, to inspect, and to repair the appliance. |
