Advice needed to replace an old EIB dimmer

[frede]

Hello,

I want to replace an old Gira dimmer that's not working properly with led bulbs (flickering occurs). I have 5 other Siemens EIB dimmer that work ok (but some are no more in use...).

All theses dimmers seem to be interconnected and don't have the red and black connectors to the bus that modern KNX dimmers have...

I don't want to make a mistake so I'm asking for advice to buy a replacement device for the Gira dimmer. I suppose that if I keep the connections the same I should be fine. I don't know if I need to use red and black bus connectors for the new device.

For information, I tried to put Hue White Ambiance bulbs and they flicker like crazy (EIB dimmer at 100% of course).

Thanks already for your help.

Here are pictures of the dimmer(s) and of my system (a wire mess):

Some time ago KNX used a so called data-track, it is behind the modules. So when you remove one module, you will see it. The connection to the track are the small 1TE elements in each line.
Just replace the old modules with a new one and connect them by cable. Data tracks are no longer used today.
