I have two double 3-way switches one upstairs and one downstairs. The bottom toggle on both switch controls the living room and the top toggle controls the top upstairs hall light. The problem is that for the downstairs light (the only one I hooked up as of now) is that the top switch must be on for the light to be on. I connected the 12/3 wiring to what I think it should be hooked up to, namely A1 (traveler) going to A1 on switch 2 and B1 (line) going to B1 on switch 2. Obviously I want 3 way switching behavior but the product diagram doesn't include a diagram for double 3 way to double 3 way switch connections. Can anybody help so I can work on the other light??
