Abstract

PURPOSE:To prevent unnecessary power consumption by a load by detecting the day before a day off automatically and then switching an automatic controller for the load to a day-off mode automatically after a store is closed on the day before the day off. CONSTITUTION:One day-off setting switch corresponds to a day off among day-off setting swithes 4-1, 4-2-4-7 is turned off previously. In a time setter 13, closing time is set in advance. At twelve o'clock midnight on the day before the day off, a shift register 3 which generates a signal showing a day of the week one day earlier than normal generates an output and the output of an OR gate 6-2 goes up to a 1. At the closing time, a comparator 12 outputs a 1, so an AND gate 11 outputs a 1, thereby switching an automatic controller to a day-off mode through a terminal 10. On the actual day off, the output of a register 1 for the normal calender inverts the output of an OR gate 8 to a 1, thus setting the day-off mode.
