I just purchased a opensprinkler v3.0 ac powered model. Before I rip out my old rain bird timer I wanted to make sure I was going to be able to nail wiring the first time with a orbit pump start relay 57009-PS2 and 3 zones (orbit 3 zone manifold). My question is whether I purchased the correct version of the opensprinkler unit (ac powered ) for my current configuration. I have attached two pictures of the current wiring, and if I just follow it to a “T” on the opensprinkler unit. And then do I define zone 1 as the master valve, as the com wire would go to a com port and then zone 1 would be defined after setup as the master valve?
Let me know if I have my head wrapped around this, and thank you.
Pump start relay is typically wired up just like a normal sprinkler zone: there is a common wire, and there is a pump start relay wire (think of it as a zone wire). On other sprinkler controllers, there is often a dedicated port for pump starter relay (or master zone), on OpenSprinkler, it is software defined, and in general you can just dedicate zone 1 for it (in software you can define any zone as the master zone).
