The timer circuit 5 counts time and provides it to a central control circuit 8 that controls the entire device. The main memory 6 stores control programs and various data that control the operation of the equipment, and a storage area configured with a RAM etc. stores information such as the presence/absence of a program in which storage instruction flags 6a and operating conditions are set in advance, and information about the equipment. Storage areas 6b, 6c, and 6d are provided to store control programs for time conditions for turning on the device and time conditions for turning off the device, respectively. In this embodiment, storage areas corresponding to eight types of devices are provided.

The I/O port 7 controls input/output of on/off control signals to a plurality of devices (not shown). on/
The off control switch 9 directly controls on/off of the device without depending on a program in which operating conditions are set in advance. The storage instruction switch 10 is a means for instructing whether or not the time of the on/off operation by the on/off control switch 9 and whether the on/off operation was performed are to be stored in a predetermined area of the main memory 6. , when storage is instructed by the storage instruction switch 10, the storage instruction flag 6a is set.

The operation of controlling on/off of devices by the home controller according to the present invention as described above will be explained based on the flowcharts shown in FIGS. 2 to 4. Note that for convenience, a control operation for one device will be explained. First, the storage instruction flag 6a is cleared (S0), and the device control program storage areas 6b, 6c, and 6d are cleared (S0).
1). Determine whether the storage instruction switch 10 is on or off (S
2) If it is off, jump to S5. If it is on, determine whether to set/clear the storage instruction flag 6a (S3)
, if it is in the set state, jump to S7. If it is in the clear state, set the storage instruction flag 6a and return to S2, and S3
Then jump to S7.

If the storage instruction switch 10 is off in S2, it is determined whether the storage instruction flag 6a is set or cleared (S5), and if it is set, the storage instruction flag 6a is cleared (S6) and the process jumps to S17. , if it is in a clear state, jump to S7. It is determined whether there is a change in the on/off control switch 9 (S7), and if there is no change, the process jumps to S17. If there is a change, it is determined whether the on/off control switch 9 is on or off (S8), and if it is off, the process jumps to S13, and if it is on, the device is controlled to be turned on via the I/O port 7 (S9).

The device is turned on (S9), and it is determined whether the storage instruction flag 6a is set or cleared (S10). If it is in the clear state, jump to S17, and if it is in the set state, the memory area 6b is set to the program presence state (S11), the on time of the device is read from the timer circuit 5, and the memory area 6c is read.

If it is in the present state, the storage area 6c is checked and it is determined whether the ON time is stored (S18). If the on time is not stored, the process jumps to S21. If the on time is stored, the on time in the storage area 6c is compared with the current time (S19), and if they do not match, the process jumps to S21. If they match, turn on the device via I/O port 7 (S
20), return to S2.

[0015] In S21, the storage area 6d is checked to determine whether the off time is stored. If the off time is not stored, the process jumps to S2. If the off time is stored, the off time in the storage area 6d is compared with the current time (S22), and if they do not match, the process jumps to S2. If they match, turn off the device via I/O port 7 (S
23), return to S2.

[0016] To clear the on/off times of devices set as described above, either start the programs shown in Figures 2 to 4 from the beginning, or provide program clearing means for each device. , the storage area 6b is set to have no program.
