I had the system working fine for the second half of the summer and when winter came around I blew out my lines and everything was fine. Today, I opened the ball valve and zone 1 immediately went on, even though nothing was scheduled. It would not turn off or move to a different zone.
things I tried:
1. unplugging rachio - zone 1 still ran
2. running a different zone - zone 1 still ran
nothing had changed from last year around the house and everything worked fine when I shutils he system down for the year.
any ideas, is the rachio bad now?
