I wonder how they do that, maybe one flow switch on the supply side and one on the return side of the solar (when supply is off, low speed. When supply is on/return off, high speed. When supply on/return on, low speed again maybe ?) When I spoke to Ikeric, basically they said that they normally set it up so the pump kicked up the whole time solar is on (using one solar switch), but the kick up was dialed in so that it just had enough head to push the water up and fill the system, but no more. They were a bit disappointed that I only had the pool and solar, they really like running to multiple outlets so they can have the pump doing lots of different settings.

It would be much easier to be a guinea pig if the pump wasn't twice the cost of a top end 2 speed! But, at least according to Ikeric, their numbers even beat a well setup 2 speed. Plus, my current pump is so d*mn loud!
