Just got my Rachio 3 system to replace the Hunter system installed in the house we recently purchased. Setup went fine with 8 out of the 9 zones but Zone 2 can be turned on by the Rachio but nothing can turn it off. The Racho app, hardware button, even pulling the plug does not turn it off. My only recourse is turning off water supply to irrigation. The other 8 zones turn on/off as they should. I tried moving Zone 2 to one of the other extra zones on the Rachio, re-ran setup for the new zone and still have the issue. I was thinking valve or solenoid until I decided to hook back up the Hunter controller to check. Zone 2 works perfectly with the Hunter controller.
Any ideas? Why would one single zone not work with Rachio?
