<p>PURPOSE:To reduce wasteful use of energy by outputting a signal for closing a water supply valve from an operation control function part at a set time based on output data from a calendar function part for ticking the time and outputting data of a date, a day of the week and the like or input data from the external part, and stopping the water supply to a hot water storage tank by said signal. CONSTITUTION:An operation control function part 19 has a schedule in which the utilization form of the water supplier is preset. The operation control function part 19 controls the action/stop of a temperature control function par 17 by use of data output from a calendar function part 18 outputting the date, the time, the day of the week, and the like at that time, while referring to the data set in the schedule and ticking the time, and a signal for closing a thermally operated valve 16 when the preset time is reached. That is, when a preset time on the operation day is reached, the water supply is stopped, and thereafter, remaining hot water in a hot water storage tank 1 is used. Thereby, the quantity of remaining water at the time of stopping the operation to reduce the westful consumption of energy and to reduce the generation of miscellaneous bacteria.</p> |
