Abstract
An improved programmable timer unit can be incorporated into a remote control management system to actuate loads according a user's defined schedule without relying upon any additional supplementary device for data communication. The timer unit includes an input section for selecting a switch address of any switch employed in the system and a schedule specifying the actuation time and the control code for actuation of the target load or loads. A processor makes up a load management program based upon the schedule and executes the program for control of loads. Thus, the timer unit can alone emulate any one of the switches for controlling loads without relying on additional external device for the data communication.
