I am trying to replace an old Rainbird RC-1260Bi with a Rachio. I have three bundles of wires which all seems straight forward enough but what is throwing me off is that common wires from each bundle are tied off to a speaker wire (???) that runs to a FloLogic 2000 system. The common wire from the Rainbird is capped off by itself.
Will this set-up work? I suppose I could start out by trying to just connect each of the zones and not touch the bundle of common wires. If that doesn’t work then try connecting each common and just discard the FloLogic wire (though I suspect that would make that system useless.) Any ideas?
