I have a Gen 2 controller which I have been using with five zones.
I have completed some work in my back yard and today connected the two new zones in positions 6 & 7, with the common wire for these two valves connected at the far right end of position 8. As soon as I powered the controller, both of these zones came on even though I still have them disabled in the Rachio app. I power cycled the controller, and the behavior remained..... I took the wire from one of my working valves in zone 4, connected it to zone 7 and it immediately turned on also. I took one of the wires from the two new zones and connected it to position 8 and it works as expected (enable zone, ran manually, then stopped, all as expected.)
I am suspicious that I have a faulty controller, and that positions 6 & 7 are somehow getting an "open" signal constantly, rather than behaving per the configuration in the controller.
Has this been encountered before? Are there further troubleshooting steps I can take? I have a backyard full of new plants that need to be watered very regularly as they take root, and I would like my Rachio to take care of this automatically for me. Please let me know any suggestions!
