Set minimum dimming level
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) STEP 3

Load table
The below table gives an overview of the permitted loads at an ambient temperature of 35 °C
Load
| | LED| |
---|---|---|---|---
| | |
Resistive| LED| Electronic transformer| Ferromagnetic transformer
Max.| 200 W| 200 W| 200 VA| 200 VA
Min.| 3 W| 3 W| 20 W| 20 W
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
| Problem | Cause | Action |
|---|
I want to use the connected dimmer but I don’t yet have a smart hub or
wireless bridge to connect it with| All 230 V connected devices for Niko Home
Control can be used in stand-alone mode until they are connected to a smart
hub or wireless bridge. In this mode, they only switch or dim their own
contacts. If extension switches are wired to the connected switch then they
can also be used in stand-alone mode| Connect the dimmer con- tact to the
lighting circuit that you want to control in stand-alone mode
My smart hub or wireless bridge doesn’t work anymore| Consult the manuals of
the wireless smart hub (552-00001) or wireless bridge (550-00640) at
www.niko.eu| If the power of the smart hub or wireless
bridge switches off, all 230 V connected devices will continue to operate in
stand-alone mode. They will only switch or dim their own contact. Consult the
respective product manuals to resolve the issue
The connected dimmer cannot be found in the Niko Home app or programming
software| The power supply is off| Switch on the power supply
The distance between the connected dimmer and the smart hub or wireless bridge
is too small| Make sure there is a distance of at least 2 meters between the
device and the smart hub or wireless bridge
The distance between the connected dimmer and the smart hub, wireless bridge
or another
connected device is too big| Make sure there is a distance of maximum 10
meters between the device and the smart hub, wireless bridge or a subsequent
230 V connected Zigbee® device. To increase the range, add, for example, an
additional smart socket outlet or Zigbee® extender
There is no connection between the Niko Home app or laptop/pc and the smart
hub or wireless bridge| Check the connection to the smart hub or wireless
bridge. Consult the respective product manuals to resolve the issue
The load does not switch on| The minimum dimming level is set too low|
Increase the minimum dimming level or a profile with boost function (LED 3,
LED 7 or LED 8)
The input voltage is not present| Check the input voltage, connection
terminals and wires, light source and dimmer. Replace if necessary
The lamp is defective
The dimmer is defective
The dimmer switches off suddenly| The protection against thermal overload
(temperature is too high) or short circuit has been activated| Check if the
lamp is dimmable. This is shown on the packaging by the 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 switch off even if the maximum dimming power has not
been reached
The temperature in the flush-mounting box should not exceed 35°C. Lower the
load connected to the dimmer
Check whether mixed loads have been used. Make sure that there is only one
type of lamp load in the lighting circuit
The dimming profile is incorrect| For 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 controlled
with lamp profiles LED 3, LED 7, or LED 8. For incandescent lamps, choose lamp
profile LED
- For halogen lamps with a ferromagnetic transformer, choose lamp profile LED
- 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 flickers| The lamp is not dimmable| Check if the lamp is dimmable.
This is shown on the packaging by the following symbol:
The minimal dimming level is set too low| Increase the minimum dimming level
or use a profile with boost function (LED 3, LED 7 or LED 8)
The 2-wire dimmer does not get enough current from the lamp| Fit one or more
LED compensators (310-05001) over the lamp, between the switching wire and the
neutral wire
The dimming profile is incorrect| Choose another profile and adjust the
minimum dimming level
There is a Power Line Communications (PLC) interference| Refer to the FAQ on
dimming at www.niko.eu/faq
The lamp has a capacitive electrical profile and generates high current peaks|
Reduce the number of lamps in the lighting circuit or replace the lamps if the
other actions listed above did not resolve the lamp flicker
The dimmer is defective| Replace the dimmer
The lamp cannot be switched off| Leakage currents can cause low power lamps to
remain illuminated (afterglow) when the electrical circuit is disconnected.
Long cabling can build up leakage currents due to capacitive effects| Fit
another lamp with a higher electrical load or install a LED compensator
(310-05001) over the lamp, between the switching wire and the neutral wire
---|---|---
The lamp is humming/ makes an audible noise| The lamp is of bad quality|
Select dimming profile LED 4, LED 5 or LED 7. When the lamp flickers, it is an
indication of a capacitive electrical behaviour. In that case, we recommend
fitting a different lamp
When I use the MIN DIM LEVEL button, I cannot switch the lamp back on| The
minimum dimming level is below the lamp’s power-on level| Select a dimming
profile with boost function: LED 3, LED 7 or LED 8
