PURPOSE:To always display the correct state of load for a remote controller that controls the load by the control signal given from an operating device and at the same time displays the state of load, by providing a switch that scans the state of the terminal unit to the operating device. CONSTITUTION:When the control signal given from an operating device 12 is applied to each terminal unit 13, the designated terminal unit 13 controls a connected load 14. At the same time, the state of load is displayed on a display device 19. A scanning switch 21 is provided to the device 12, and the device 12 scans the unit 13 to detect the state of load and then display it on the device 19 at the moment the switch 21 is operated. Thus a correct display is ensured by operating the switch 21 when necessary and although the local control is carried out at the side of the unit 13. |
