I have 2nd Gen controller running a well pump via a Hunter pump start relay. Also connected to the pump start relay is my neighbor’s Hunter Pro C controller. We share the well…
Their sprinkler guy said my 2nd Gen is causing an error on their system when both are hooked up. With only one controller hooked up, each works fine. When their controller comes on, the pump start relay cycles on-off very quickly several times before the Hunter Controller errors out.
Is there a pump start relay that will work with both controllers that you know of?
