Just came across this thread. I have a 20k IG and would like to upgrade to basic automation, SWG, and VS pump. I am leaning toward the ProLogic PS4 w/ T-25 SWG and Pentair SuperFlo VS Variable Speed Pool Pump. I also plan to add solar at the same time. I would like the pump automation integration, but believe an Echostar would be overkill for my application. It looks like I can use one of the relays to trigger a speed on the Pentair like a 2-speed pump. The Hayward superflow VS doesn't even have those inputs for basic remote control.
