2nd all that. I would add that since you want all this to run array direct, you need to be VERY aware of the MAX voltage of both the relay and contacts that the switch can handle. If it's a summer only gig, you can probably go with Voc.

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.
