I am setting up the Iro and it's asking whether to use a Master Valve/Pump. What does this mean? I have 12 valves using 4 separate cables but I don't know whether I have a 'master' valve.
@radamio Here is a good description of a master valve.
If you have any wiring questions you can reach out to email@example.com and we have wiring professionals that would be glad to help you with your install. Thanks and let us know if you have any more questions or feedback.
Thanks, I realize I don't have a master valve based on that diagram.
