Abstract
A load terminal for use in a remote controlled load management system includes a control unit for starting to count a delay time and sending to a central controller monitoring data indicating that an illumination load has been turned off while controlling a power supply ON/OFF unit to keep the power supply to the illumination load when a transmission signal including a control data instructing to turn off the illumination load is received by a transmission signal transceiver unit. The control unit restarts the count of the delay time when the transmission signal transceiver unit receives a transmission signal including a control data instructing to turn on the illumination load during the count of the delay time from the central controller.
