Good news I think! I went into SolarTouch > Advanced > Manual Mode and by manually activating Booster Pump it started up speed one on my Whisperflo pump. This tells me the relay works.
Set speed 1 to the speed you want for Solar. I used 3000.
After exiting Manual Mode the IntelliFlo Com Lost warning was gone and the green LED lit. I think this told SolarTouch I’m not using IntelliFlo.
Here is a wiring schematic for those who like me wonder why Pentair can’t just write simple instructions for their very own Whisperflo VST and SolarTouch. Hope this helps. And thanks everyone for the guidance here.
