Fig. 1 and Fig. 2 show the front view and the back view of the BRT-D205 LED dimmer switch

  respectively. It has a rotary knob on the front and wiring terminal blocks on the back.

  BRT-D205 LED dimmer switch is design to replace the legacy dimmers in most homes. It can fit

  into standard wall box for easy retrofit installation.

  * For most dimmable LED lights. The dimming range can vary from LED light to manufacturer. Dimmable LED lights usually will not achieve as low a light level as incandescent or halogen sources.

  BRT-D205 LED dimmer switch only requires two wires for installation:

               Hot wire (ACL):    Coming from the power line with 220V; and

               Load wire:             Going to the load.

  Warning: Please make sure power is turned off before starting installation!

  One BRT-D205 LED dimmer switch can be wired in a single-pole configuration as shown in Fig.

  3 or two BRT-D205 LED dimmer switches can be wired in a three-way configuration to control

  the same LED light as shown in Fig. 4.

  Fig 5 shows five steps to install BRT-D205 LED dimmer switch:

              Step one:      Remove the knob middle plate and front plate;

              Step two:      Adjust the locations of two jumpers (pointed by red arrows) to match the LED

                                  light power according to Look-up Table 1;

              Step three:    Wiring according to the diagram and the labelled ports of the switch;

              Step four:      Install the base plate to the wall box using screw driver and screws; and

              Step four:      Re-assemble the front plate middle plate and knob.

  Note:     It is very important to adjust the jumper locations to match the LED light power rating for

          the best dimming performance during installation.

  BRT-D205 LED dimmer switch uses two adjustable jumper caps to optimize dimming

  performance for different LED light power loads. Please calculate the power load and plug the

  jumper caps properly according to look-up table 1 as follows:

  BRT-D205 LED dimmer switch is very easy to operate.

  On/Off:          The rotary knob is a push button as well. Pushing the knob will turn on the light

                          and pushing again will turn off the light.

  Dimming:       Once the light is turned on rotating the knob clockwise will increase brightness

                          and rotating the knob counter-clockwise will decrease brightness.

  For some LED lights dimming range may be limited and there may be flickering.The dimmer can

  be tuned to achieve the best performance. Performance optimization is realized by adjusting the

  two tuning screws behind the middle plate as shown in Fig. 6.

  Please make sure that the jumper caps are set up properly during installation before proceeding to

  the following procedures.

  Adjusting Minimum Brightness:

  1.     Turn on the LED light and rotate the knob to have minimum brightness;

  2.     Remove the knob and the middle plate to have access to the two tuning screws as shown in

           Fig. 6; and

  3.     Use a screw driver to tune the “Coarse” screw to reduce the minimum brightness further.

  If there is flickering please go to the next procedure: Eliminating Flickering.

  Eliminating Flickering:

  1.     If there is flickering remove the knob and the middle plate to have access to the two tuning

           screws as shown in Fig. 6;

  2.     Use a screw driver to tune the “Fine” screw to eliminate or reduce flickering

  3.     If flickering persists use a screw driver to tune the “Coarse” screw to increase the

           minimum brightness slightly. Go back to Step 2 to adjust th“Fine” screw;

  4.     Re-assemble the middle plate and the knob.

  Note:    Dimming performance depends on LED lights to a certain degree. If the performance is

  still unacceptable after going thorough the performanceoptimizatio n procedures please talk to our

  sales representative. Further customization can be done at our factory.
