The first button press ‘Select Profile’ will indicate which lamp profile is configured in the dimmer (count the number of green LED flashes which are repeated three times).

Set minimum dimming level

Set the minimum light intensity
Adjust the minimum dimming level to make use of the optimal dimming range of the lamp connected to the dimmer. The minimum dimming level is set as follows:

Dim the lamp to the minimum level using the dimming button in the middle of the base
Check the intensity of the lamp:
- If the lamp is on at the desired minimum light level, the dimmer is correctly configured
- If the lamp still shines too bright, reduce the minimum dimming level using the MIN DIM LEVEL button. Continue to dim the lamp to a point where it does not flash or switch off
- If the lamp is flashing or is completely switched off, increase the minimum dimming level in the same way
Save the new setting by switching the dimmer off and back on. If the lamp does not switch on, configure a dimming profile with boost function (LED 3, LED 7 or LED 8)

Load table

The dimmable capacity decreases by 10 % per 5 °C once the ambient temperature exceeds 35 °C

By placing several dimmers on top of each other, or in an insulating wall (plaster or wood), it is possible that the temperature of the dimmer rises above 35 °C. The above power graph will then apply.

Troubleshooting

The dimmer switches off sud- denlyThe protection against thermal overload (temperature is too high) or short circuit has been activatedCheck if the lamp is dimmable. This is shown on the packaging bythe following symbol:Check if the load is too high. Remember to take into account the reactive power of ferromagnetic transformers. Led lamps that generate peak currents can also cause the dimmer to switchoff even if the maximum dimming power has not been reachedThe temperature in the flush-mounting box should not exceed 35°C. Lower the load that is connected to the dimmerCheck whether mixed loads have been used. Make sure that there is only one type of lamp load in the lighting circuitFor LED lamps: Test all lamp profiles one by one and choose the profile that works best. Dimmable LED lamps that require a boost function (which do not start up at minimum dimming) can be con- trolled with lamp profiles LED 3, LED 7, or LED 8.For incandescent lamps, choose lamp profile LED 1. For halogen lamps with a ferromagnetic transformer, choose lamp profile LED2. For LED lamps supplied with a ferromagnetic transformer, choose lamp profile LED 3. For halogen lamps with an electronic transformer, choose lamp profile LED 5.The lamp flickersCheck if the lamp is dimmable. This is shown on the packaging bythe following symbol:Increase the minimum dimming level or use a profile with boost function (LED 3, LED 7 or LED 8).Fit one or more LED com- pensators (310-05001) over the lamp, between the switching wire and the neutral wireChoose another profile and adjust the minimum dimming level.Refer to the FAQ on dim- ming at www.niko.eu/faqReduce the number of lamps in the lighting circuit or replace the lamps if the other actions listed above did not resolve the lamp flickerReplace the dimmer
