But You could use a pool flow controller. Jandy has a valve actuator that you can program % of open and close. It would require the IAquaLink controller but that integrates seemlessly with control 4
By the time you factor your time, figuring out how to provide voltages and then build a driver in C4 using the jandy valve and iAquaLink would probably be cheaper.
