Re: [RE-wrenches] Timer for SQF pump

[Allan Sindelar]

Agree with Jerry on using the float switch circuit. The one note I would add is that the Grundfos CU200 "controller" uses a conventional close-on-rise signal algorithm. So a timer would have to be set in reverse - that is, an "on" closed-contact signal from the timer would turn the pump off, so you'd want to program the timer to "off" when you want the pump to run.
