My current controller RainBird ESP 8SI has 2 stations with 2 main solenoids (one at each station box) with only a total of 8 zones (4 at each station). Is there a wiring diagram or how can I install to the Rachio 8 zone system?
Good evening. Here’s a wiring diagram to reference. To my understanding, you have two master valves?
I’d be happy to help you wire the wall mount if you could send a photo of your old timer’s wiring to email@example.com.
Thanks for your support!
