Abstract

A timer processing section 10 instructs a transmission processing section 11 to control load in accordance with a time schedule stored in a program storage section 12. The transmission processing section 11 is connected to a two-wire signal line and gives a load control instruction to each terminal to which load is connected according to a time-division multiplex transmission system. The time schedule stored in a program storage section 12 is a set of the address related to the load to be controlled and the control contents and the control time of the load. Therefore, when the time set according to the time schedule is reached, the load specified by the address is controlled.
