As part of a new solar heat install, my contractor installed an Sta Rite VS 3050 (Model P6E6Y4H-209L) multi speed pump. The solar array is way up on the far side of a two story roof, and the pump needs to be on a high speed to move adequate water up to and through the panels. I already have an Aqualink RS control panel. Can I connect the VS 3050 directly to the Aqualink (through the correct RS cable) so that I can set the pump speed to reduce RPM when the solar is not needed? If so, can this be handled by me or should I get a contractor? I'm handy mechanically.
