Linking the Dimmer to a Channel

First you need to link the dimmer to one of the channels in the left panel as follows:

1. Select the dimmer in the left panel and click Link Channel.

2. The Dimmer linking window will appear with guided instruction.

3. Press and hold both buttons labeled 1 and 2 on the dimmer.

4. LEDs will start blinking blue.

5. Press one button to link corresponding channel ID (0 or 1) and click Link.

6. Optionally, select Link both channels at once to save time.

7. When a dimmer is linked, its configuration options appear in the right panel.

Dimmer Configuration

The following fields are available:

1. Product
   Fixed as Dimmer LED. This field is not editable.

2. Name
   Assign a custom name to the dimmer for easy identification.

3. Channel ID
   Unique identifier for the dimmer channel.

4. Link/Unlink Channel
   A button to link/unlink this channel.

5. Serial number
   Displays the serial number of the dimmer.

6. Channel
   Indicates the channel number (up to 64) and its physical position (left or right) on the dimmer.

7. Fade up / Fade down (in milliseconds)
   Defines the time it takes for the light to fade up or down when dimming is triggered.

8. Ramp time (in seconds)
   Sets the duration for transitioning between dimming levels.

9. Load type
   Specifies the type of load connected:

   • Automatic load detection

   • Resistive-capacitive load

   • Resistive-inductive load

   TIP: If you are unsure, starting with Automatic load detection is recommended.

10. Max. level / Min. level (in %)
    Defines the upper and lower brightness limits for the dimmer.

11. Select objects
    Each dimmer can be linked to multiple KNX group objects for full integration. You can select an already created object or create a new one for each of the following:

    • Status: KNX group object for on/off status.

    • Dimming: KNX group object for dimming control (0 – 100 %).

    • Level: KNX group object for setting brightness level.

    • Level feedback: KNX group object for reporting current brightness.

    • Status feedback: KNX group object for reporting on/off state.

Once all parameters are configured, click Save changes to apply and store the settings.

This ensures the dimmer is correctly mapped and fully functional within the KNX system.
