Dimmer RDP-21 is designed to control illumination lamp fitted with conventional incandescent and halogen AC 230 V and a light source supplied by an electronic transformer or toroidal. Changing the illumination is also possible for selected dimmable LED bulbs and dimmable CFL. Dimmer control can be performed wirelessly from the transmitter or controller EXTA LIFE and the wire from the connector single monostable or bistable. To control wire is used to input IN configured in the mobile application. With two-way communication between the receiver and the current state of the dimmer controller is shown in a mobile application (ON / OFF status + illuminance level in%).Such a way of communication also allows the receiver and remote parameterization adding transmitters (without physical access to the receiver). Frame encoding algorithm ensures security control. RDP-off controller 21 can be operated in parallel from the system transmitters EXTA LIFE. The receiver can enter more transmitters which enables independent control of several places. The device is designed for installation in installation boxes underground and surface-mounted. The receiver has implemented the function of remote software update from the controller. The programmed times fade in and fade, and sets the minimum and maximum light dimmer extra functionality.Frame encoding algorithm ensures security control.
