5. Operating Instructions
The HOFTRONIC Universal LED Dimmer provides smooth and silent dimming for compatible LED lamps from 3W to 200W.
- Switching On/Off: Press the rotary knob to switch the connected lights ON or OFF.
- Dimming: Rotate the knob clockwise to increase brightness and counter-clockwise to decrease brightness.
- Silent Operation: This dimmer utilizes trailing edge technology for silent operation, preventing buzzing and flickering with compatible LED lights.
- Minimum Brightness Adjustment (MIN): The dimmer features a minimum brightness adjustment screw (often labeled "MIN"). If your lights flicker at low settings or do not dim low enough, you can adjust this screw with a small screwdriver to set the optimal minimum brightness level.
This image provides a detailed view of the dimmer module, highlighting the "MIN" adjustment screw which allows users to fine-tune the minimum brightness level for optimal performance with various LED lamps.

The HOFTRONIC LED Dimmer requires minimal maintenance.
- Cleaning: To clean the dimmer's surface, gently wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components.
- No User-Serviceable Parts: There are no user-serviceable parts inside the dimmer module. Do not attempt to open or repair the unit.
7. Troubleshooting
If you experience issues with your dimmer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn ON/OFF. | No power supply; loose wiring; faulty bulb. | Check circuit breaker. Ensure wiring is secure (power off first!). Test with a known working bulb. |
| Lights flicker or buzz. | Incompatible LED bulbs; load too low/high; MIN setting incorrect. | Ensure LED bulbs are "dimmable" and compatible with trailing edge dimmers. Adjust the MIN setting. Verify total load is within 3W-200W. |
| Dimmer does not dim smoothly or to desired level. | Incompatible LED bulbs; MIN setting incorrect. | Use high-quality dimmable LED bulbs. Adjust the MIN setting to optimize the dimming range. |
| Dimmer feels warm. | Normal operation; overloaded circuit. | A slight warmth is normal during operation. If it's excessively hot, immediately switch off power and check total load. Ensure it does not exceed 200W for LED. |
If the problem persists after trying these solutions, please contact HOFTRONIC customer support.
