Woke in morning to see all zones running. The only way to turn off sprinkler is to remove the ‘C’ wire. Tried unplugging and rebooting the unit. But once i reconnect the C wire…all 7 zones turn on. This happend with an older rachio unit…and now same thing with a completely different unit (rachio 3). Newer unit worked great last season and the start of this season. And all of sudden wont turn off. Dont know what to do? If i can tfigure this out….i am done with rachio….
If you disconnect one of the zone wires, does that zone stop watering? Do you know how old your valves are?
