I am trying to install GE 12722 and 12723 switches on a three way circuit but ran into an issue. I have a switch at the bottom of the stairs and one at the top of the stairs. In between are three lights controlled by both switches. I pulled the wiring and it looks like this diagram (option 4):
I can get the 12722 switch to work at the top of the stairs (the switch on left if you are looking at the picture) but the issue is the AUX switch (12723) at the bottom of the stairs (the switch on the right if you are looking at the picture). It requires just a traveler and neutral. The second box were I want to install the AUX switch has 3 wires (a traveler and 2 hots but no neutral). Anyway to re-purpose my existing wiring to accomplish this. I know that the new z-wave switches don’t require as many wires but I am not sure which of the two hots I can re-purpose by just switching the connections at the light. I would leave the traveler alone.
