Information on LED dimming
230V LED dimming of lights / strips
With the Loxone Dimmer you can dim common 230V LED lights and strips.
You can dim all 230V LED bulbs marked as dimmable with the Loxone Dimmer. Due to the electronic control LED bulbs require different correction values on the Dimmer to allow for smooth dimming. This list should help you find suitable LED bulbs and their correction values.

- Mount the Dimmer Extension on the DIN rail
- Connect 24V DC power supply, but do not switch on until the whole installation is completed
(We recommend looping through the Miniserver)
- Connect the inputs and outputs
(We recommend splitting the channels of the dimmer across 3 phases)
- Connect the Loxone Link
- Note: If it's the last extension, terminate the Loxone Link with a 120Ω resistor (included with the Miniserver)
- Turn on the power supply
- After a few seconds, the left LED will flash green if the extension is already configured, or orange if not
- Inductive loads (e.g. conventional transformers) and capacitive loads (e.g. electronic transformers) must not be interconnected!
- Conventional transformers must be loaded with at least 80% of the nominal load with lamps.
- The Dimmer Extension is not suitable for speed control of motors, since back EMF with voltage spikes of over 300 V causes permanent damage. If you have any questions regarding this please contact Support.
- When using the Dimmer for mains LEDs each channel should be de-rated by 50% due to the high inrush currents. This means that the first channel would be rated at 200 Watts and the other channels at 105 Watts.
Make sure that your bulbs are labelled as dimmable - especially with energy saving bulbs and LEDs.
Insert an extension into Loxone Config with connected Extensions
To add one or more extensions to the program the simplest way is to connect up the extensions to the Miniserver using the Loxone Link and looping power. Then do a search in Loxone Config, which will bring up the Miniserver and all the connected extensions. you can highlight a single extension give it a name and then click Create device which will add in the highlighted extension. Or you can click on Create all devices which will add all the connected extensions in to the program with the correct serial numbers.
Insert an Extension into Loxone Config with no connected Extensions
If there is no physical extension connected to the Miniserver this cannot be found in the search. However you can already add the extensions to the program. In the configuration software, connect to your Miniserver and download the existing configuration (if there is one) from the Miniserver. Select the 'Devices' drop-down menu on the Periphery tab and select the required extension. All the extension's inputs and outputs are available for you to use in the Periphery tree.
Enter the serial number
Click on the Dimmer in the periphery tree. Enter the serial number of your Dimmer in the properties section.
The serial number is on the back of your Dimmer Extension. You can find the number just below the barcode (see picture).
Using the Dimmer extension
The Loxone Dimmer Extension is an RLC Dimmer. That means you can dim resistive, inductive and capacitive loads. The maximum power is 210 Watts per channel.
Here you can change what type of load is being dimmed.
|Dimming type||Type of load||Example|
|Leading edge dimming||Resitive or inductive load||Incandescent bulbs, conventional NV-Halogen transformers|
|Trailing edge dimming||Capacitive loads||Electronic NV-Halogen transformers|
|HV LEDs||Capacitive loads||High voltage LEDs|
In the 'Properties' window of the actuator 'Perception correction' can be ticked. The human eye perceives changes in brightness in dark rooms more intensely than in lighter rooms. Therefore, dimming changes from 0 -100% are perceived very quickly at first and somewhat slower as brightness increases. To create a smooth transition, perception correction can be activated.
If an incoming value is outside the range (0 to 10) for instance 0-100% with 0-10VDC, this can be adjusted for using the corrector.
Correction example for a dimmer
The analogue output from the dimmer function block gives out a 0-10V signal, the output of the Dimmer Extension is 0-100%, so the corrector must be used for the scaling to be correct. The scaling is linear. If 1V at the analogue output corresponds to 10%, then the following settings must be used:
|Input voltage 1||0V|
|Display value 1||
Input voltage 2
Display value 2
Since high voltage LEDs have their own electronics, it might be that at 70%, they are already at their full brightness. The corrector can also be used here:
|Input voltage 1||0|
Display value 1
Input voltage 2
|Display value 2||
