Warning: Please make sure power is turned off before starting installation!
One BRT-D204 LED dimmer switch can be wired in a single-pole configuration as shown in Fig. 3 or two BRT-D204 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-D204 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 ba
Step four: Re-assemble the front plate middle plate and knob.
Fig.5 BRT-D204 Installation Guide
It is very important to adjust the jumper locations to match the LED light power rating for the best dimming performance during installation.
BRT-D204 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:
Look-up Table 1: LED Light Load Power vs. Jumper Locations
The jumper caps can only be unplugged or plugged when the line voltage is not applied to the dimmer switch.
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.
Once the light is turned on rotating the knob clockwise will increase brightness and rotating the knob counter-clockwise will decrease brightness. switch.
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.
Fig.6 Performance Optimization of BRT-D204
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 the “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 performance optimization procedures please talk to our sales representative. Further customization can be done at our factory.
