I have two sets of lights in one room, on separate circuits, controlled via an 2-gang on/off switch by the door and a 2-gang dimmer switch at the other end of the room. I would like to replace these with LighwaverRF dimmer switches in both locations.
Replacing the existing 2-gang dimmer switch with a 2-gang master dimmer should be relatively straight-forward, but I am unsure as to whether the on/off switch needs to be replaced by a 2-gang master dimmer or 2-gang slave dimmer.
Any advice gratefully received.
You need a 2 gang master in one location and a 2 gang slave in the other.
You can’t leave an on/off switch in place as that would cut the power to the other LightwaveRF unit.
I would also do a quick check behind the existing switches first as 2 way wiring does have some variations. If you have 3 wires (not counting earth) for each gang then the wiring is normal and the replacement should be fine.
