I believe my controller is a resol as well.
The one you chose is fine..
The resol has some a few more benes then the less expensive ones but they all basically do the same important things.
Turn the pump on when the collector is hotter then the storage tank water.
Bingo.. you're done. Ha
The one I have runs the pump at high speed for about 5 seconds to help push the water up to the roof and thru the collectors.
The second the water begins retrieving from the roof the pump speed drops down to a slower speed which allows the water going thru the collectors to pick up a little more heat from the collector headers. I'm using evacuated tube collectors. (ONLY WAY TO GO, I love these things)
