In a remote monitoring and controlling system, a selector switch unit sets data for batch controlling and for separately controlling operation of illumination loads and transmitting to the signal line a control request signal related to operation for the illumination loads based on the set data. A data memory stores therein set operation states of respective illumination loads and set dimming levels of respective illumination loads so that the operation states and the dimming levels are associated in correspondence therebetween. A control request signal containing the data stored in the data memory is transferred to a terminal unit. The terminal unit transmits a dimming level instruction signal to its corresponding dimming terminal unit based on a control request signal of dimming level from the selector switch unit, and further transmits a display instruction signal of dimming level to the selector switch unit, thereby displaying a current dimming level.
