I replaced my Rainbird ESP-8Si with the Rachio 3 controller. When I got to the test zones part of setup, the zones are not activating. It worked prior to repacking the Rainbird. And there were only 3 wires: Red for Zone 1, Blue for Zone 2, and a White coms wire. I put the red into the 1 slot and blue into the 2 slot and tried the white wire in both C slots.
What do I do next?
