Most of the larger PSR's I deal with use 110 coils.
The TECO was installed by me. As Sprinkus said, I need the ice cube because the controller puts out 24V to the Master valve, and the PSR is a 110V coil (Mike, the Ice Cube is a 24V switch that sends a 110V to the PSR.)
It's the first Teco I've installed but not the first PSR. I've had to use ice cubes with the older Rainbird LX series (dominant in my market area). Hoover Systems on the other hand use a 110V.
I would not consider using a Hunter, k-Rain or Orbit PSR's on commercial installations.
I'm going to re-check all the wiring (3rd time) then test, if no success , I'll by pass the sprinkler sub panel. I still think I have a load issue, 40AMP is on the cusp for a 7.5HP motor and controller.
Great input, I really appreciate it, Thanks!
