I have something similar to this going on:
Basically, my office only has one device: A ceiling fan that has an integrated light. On the wall, two switches - one controls the fan, the other controls the fan light.
Here’s how the existing basic 3 prong switches were wired:
So the fan is wired with 2 black, one bare wire.
The light is wired with one black, one red, one bare wire.
From the link above, I presume that what’s actually coming from the fan is one set of wires as the load (red=light, black=fan), then I have 2 black wires from the Source, and finally 2 bare ground wires.
(sorry for the link instead of an image, the forum said I could only post one picture)
Here’s where I’m running into issues. I’ve tried to swap in the GE ZWave to either side, and neither seems to work. At first I was thrown off by the red wire, so I tried just hooking the switch up to Fan side… so black wires connecting to the Line & Load terminals, and the bare connecting to the ground. Switch does nothing.
Tried connecting it to the Light side (bare to ground, red to load, black to line)… nothing. I swap the old plain switches back in, fan/light works fine. I was so confused by these results that I figured my GE switch was just bad, so I returned it and got another one - but the replacement isn’t working either, so I must be doing something wrong.
I don’t get it?
