 no worries, thanks for keeping me on my toes!  it is appreciated 
I run a profilux controller, but I'm pretty sure all the controllers out there have level sensor inputs?  I don't know for sure as I've never seen any other one in person, but I would assume that they do?
My profilux actually has 3 level inputs.  I use one for a fresh water auto-top-off, and the other two are being used for the automatic water change tank.
