Three pattern control switches S, -S3 were provided, allowing pattern control of a plurality of loads at once using different control patterns. Note that the switch S is 'd! This is a mode changeover switch that changes between normal mode and setting mode.

Now, the central control device accesses the monitoring terminal device 2, returns monitoring data indicating the operating states of the switches S, to S4, and selects a control pattern (preset pattern) based on the returned monitoring data. Load control data is created to collectively control multiple loads using a control terminal (pattern), and this load control data is accessed through a control terminal and time-division multiplexed for transmission to perform load control.

In addition, the presence of unnecessary switches may cause confusion in operation or lead to erroneous operations. In addition, the monitoring terminals 2 of the pattern control switches S, ~S3 and other wiring devices can be connected to the same wiring device mounting frame (
In general, there was a problem that it could not be installed in parallel with the 3-port type.
