Anyway abt return to chiller, I don't really care abt the flow through chiller etc logic. Used to but gave up because putting another correct flow rate pump just adds heat to the equation when the idea of modification is to reduce it.
Since it's an enclosed system running on cool Lightings like led I don't think it is gg to make a lot of diff anymore if u use slow or fast rated pumps for chiller. Return to chiller direct now works for me. Save money save the world save the earth (:
