I woke up yesterday and my C-Bus was not responding correctly - Switch lights were flashing when activated which indicates a problem on the bus. I tracked it down to one of my L5512RVF units - As soon as I disconnected it from the C-Bus, everything came back to life. If I plug it back in, I can hear a constant clicking and the C-Bus stops working. I tried to use the Clipal support chat, but they directed me to contact an "eco-expert". The closest of which is over 100km away and if they are even interested in helping will probably charge me a fortune just to look at the problem. Is there a repair option available for this unit? Or do I just replace it?
