Hello all — just bought a Rachio 3 and we’re working on the installation. I’ve got a question I’m hoping someone can help me with. The issue I have is that the old box setup has two wires connected to a “line” port, and I’m not sure how those should connect to the Rachio. I thought they might go into the common port on the Rachio, but I already have a common wire and that would leave me with three common wires and only two ports on the Rachio.
Anyway, I tried to search for it on here and elsewhere, but came up empty. I’ve attached the photo here, I’m hoping it’s a quick and obvious solution. Any help is appreciated. Thanks! —Jason
