PURPOSE:To control a variety of devices by providing a clock means in addition to a temperature control means, providing respective means for temperature and time setting and time comparison, and performing control operation at set time in addition to set time. CONSTITUTION:A RAM 8 for temperature and a RAM 9 for time data are coupled with a CPU 6 in addition to a ROM 7 and the control operation is performed according to a program stored in the ROM 7. Detected temperature and time, etc., are stored in the RAMs 8 and 9. Further, switches SW 1-SW 4 in a switch group 10 connected to the CPU 5 constitute a setting means for temperature and time and the CPU 5 compares the detected temperature with the set temperature and the detected time with the set time to output control signals. Further, A switch SW 5 is a selection switch for the control operation and the switch is off when a power source is normally on and the condition is satisfied, or on when the power source is normally off and the condition is satisfied according to switching setting. |
