Functioning
Lighting is turned on by a current pulse sent after pressing an impulse switch (buzzer) connected to a relay. Another mpulse switches the lighting off. Pressing and holding the switch for more than 1 second allows the user to adjust light intensity (continuous loop adjustments in the following sequence: BRIGHTER→DARKER→BRIGHTER).
Light intensity may be controlled by means of numerous switches in a parallel connection, distributed in several locations within a room.
Attention!
The SCO are adapted to co-operate with pushbuttons equipped with neon lamp.. 
Attention!
There may be working irregularities with certain electronic feeders (e.g. flickering may appear). Therefore, some feeder types require light bulbs or halogens of total power up to 50% of the feeder’s nominal.
Tests are recommended before final assembly and commission.
