Hello All, I am looking to control the flow of my chiller water for my FV's with a temp controller, control valves. I am tired of controlling them by hand. Basically I need a temp controller that tells a (I'd prefer)a pneumatic (XP rated) valve to open when needed and closed when demand is not needed. Anyone have any recommendations on a someone that does these sorts of set ups. Any thoughts? Or if I can set it up, what you use or recommend for the build out? Thanks!
