PURPOSE: To store the output of a solar battery in a secondary battery or the like and to prevent an extreme decline of a charged amount by providing a sensor for detecting a human body inside a toilet room and operating a liquid crystal display part only when the sensor detects the human body. CONSTITUTION: Power is supplied from a dry cell 2 to a control circuit 1 provided with a microcomputer. To the control circuit 1, input signals are inputted from an operation part (a shower switch and a charm switch, etc.) 3 and also human body detection signals are inputted from a human body detection sensor 4. The human body detection sensor 4 is provided in front of this remote controller. The control circuit 1 transmits control signals from a signal transmission part 5 to the hot water cleaning device of a stool based on the signals from the operation part 3. Also, when the human body detection sensor 4 detects the human body, the liquid crystal display part 6 is operated and time display, signal transmission confirmation display and battery shortage, etc., are displayed. On the other hand, when the human body detection sensor 4 does not detect the human body, the liquid crystal display part 6 is not operated. |
