After finding out about the digidim (thanks hornydragon) I have decided to get one, once that is they Email back with a UK supplier. I've read through the instalation and user manuals on there site and it can do loads of stuff, the nice thing is aswell the control plate sits on a standard 1G back box and connects to the control box via standard T&E cable so I don't need to change any of my wireing. My problem is however, I have to make one of the circuits so that it can not be dimmed, on this circuit will be a transformer which feeds some LED lights in the floor. Is there a circuit I could build that would keep the output a constant voltage even if its dimmed from the controler? I was thinking of using a 240v relay but one where the coil will still operate even if the voltage drops to say 200v, so when the output is operated it triggers the relay and it keeps the output there untill its dimmed right down and the relay then closes. Any idea? Thanks, Alex.
