Abstract

PURPOSE:To make it possible to operate a water supply controller using s battery whose performance becomes inactive when it is not used for a long time as a power source by installing a battery forced use means. CONSTITUTION:Water supply is controlled in such a way that under the control of a microprocessor 30, when the light of an LED 12 which is emitted in a given timing is reflected by the human body 13 and sensed with a light receiving device 14, a solenoid 50 of a water supply valve is actuated to operate the water supply valve. The controller uses a thionyl chloride battery as in power source. When the battery is not used for a long time, a resistant film is formed inside the battery and the performance is deteriorated. A part of the operation of a battery forced use means 61 is shared by the processor 30, and when the frequency in use of monitoring operation is less than a given value or the ambient temperature exceeds a set value, the solenoid 50 is actuated to use the battery.
