I am trying to install a motion sensor in place of a 3 way switch in a circuit with 2 switches. The model is the Levitron PR180 and Googling does show a lot of problems with this device and 3 ways.
I started by disconnecting both ends of the circuit. Upon testing the wires I determined that where I wanted the sensor was at the line end. I connected the Hot Line to the black traveler and tested at the other end. I expected black to be hot, but both black and red where hot.
Likewise back at the Line end the still disconnected red was hot. At this point the Levitron instructions ceased to be useful as they seemed to be betting on only one being hot. I called their tech support, but the guy told me my switch was "wired wrong". The switch came with the house, and worked fine before as a 3 way. I have looked at electrical manuals for the various ways to wire 3 ways and I can't see one that would leave both travelers hot, so maybe he's right.
Any advice would be appreciated.
