I have a 2hp 2spd Northstar. On low speed with all valves open I get insuffecient flow on the Autopilot. I reduced the flow to spill over spa, swimout, step jets with the valves until the flow light goes out. Marked all the valve positions and return them to these positions when I'm done running different things. Took a little time setting the valves for the flow I wanted at the different places. All in all everything works very well.
