Hi. When I activate a zone only sounds a click in valve. No water. Help!!!
@Marcoibarrag, sounds like the Iro is sending power to the solenoids correctly, but there’s no water getting to the valves. Do you have a master valve by chance? If you have any photos of the old wiring, please post them here and/or send them to the support team to review (firstname.lastname@example.org).
