PURPOSE:To automatically change an interval cycle for supplying power based on data by learning the utilizing frequency of the hot water supplier of a user. CONSTITUTION:By a signal from a switch 13 for instructing the operation, a signal for operating the hot water supplier is integrated by a counter part 18 for a fixed time, updated every fixed time and assigned to an integrated value and a time base. The integrated values and time data thus obtd. are rearranged in order of frequency by a learning part 22, and the stop period of power supply from a power source control means 17 is assigned every hour. Thus, power consumption is prevented. |
