Hello, I have some strange cbus behaviour on a dimmer circuit which I could do with some advice on please. Dimmer unit supports 8 circuits, all circuits except one are fine. The One circuit that is problematic results in the lights remaining switched on. When one of the programmed switch buttons is pressed there is a small change in the brightness of the light. previously to the issue the light circuit would switch off or dim dependimg om the sort of press. all other circuits off the 8 channel dimmer work fine. What is more peculiar, is when I press and hold one of the cbus unit buttons to program manually a command all of the lights in the house switch off except the circuit which is problematic these lights remain on. any ideas? Regards giuseppe
