Lighting dimmer SCO-814 with "memory" of lighting intensity settings, 1000W, 3 modules

The lighting dimmer is used to turn on and off incandescent and halogen lighting with the possibility of adjusting the intensity of this lighting using any momentary (bell) switch.
Action
The lighting is switched on after the current impulse caused by pressing the momentary switch (bell) connected to the relay. The lighting will be turned off after the next impulse. Holding the button> 1 sec. allows you to set the desired light intensity (smooth light pulsation in the BRIGHTER DARKER BRIGHTER loop).
Each time it is turned on, the lighting returns to the previously set brightness.
The lighting can be controlled by a number of buttons connected in parallel, located at different points in the room.
