Bought this house s couple years ago… No information turned over regarding the irrigation system. Been using the 5 zones (29 sprinklers) in manual mode since moving in without issue.
Swapping out for a Rachio 3 just now, found this brown wire just hanging out. I connected it to a zone and nothing happened. Could it be a master valve? If so, how do I test it? If it’s not, will it hurt the Rachio to wire it in?
Thanks for the help!
