<div>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.<br>

I am in need of a timer for an SQF Grundfos pump, PV direct.<br>
Would it be considered a non-inductive load?<br>
I was thinking to install the timer on the PV input side.<br>
