Hello all I'm finishing up my first IG pool. As of now my pool consist of 14x28 14k gallon salt water pool, hayward 2hp pump, lion fountains, lion spouts, sheer descent. From what my PB says is that i would have 3 valves to control these things. I also have a pool light, pavers lights, and spot light on the palm tree that I want to control. Maybe in the future I would add a electric heater to the pool. So my question is since I have all hayward products, should I go with the hayward ps-4 or ps-8 to control what I have? Thanks
