Guys, I'm in over my head I know, and most likely be enlisting an electrician, but how & where would a PSR be wired into this system? Customer has a submersible, strictly for a hydrant & now sprinklers, 3 wire, 240 V, breaker is in the basement of house, aprox. 35' away. They have a switch on a post right by the well, to turn the pump on/off. Want to be able to utilize it for the sprinklers, and turn on/off with the controller. PSR - Krain 1522 24 v - has 2 contacts for "IN" and 2 for "OUT" So which of the wires, Red, Black, Yellow get hooked up ?
