Does anyone have simple instructions and maybe screen shots that shows how this is programmed?
I have two level sensors, level splitter and 3 pump doser pulling from two separate water containers (one salt, one fresh).
During the water change, the drain pump activates via the timer, the water in the sump drops to the lower level sensor, the drain turns off, but then the ATO pump turns on instead of the new saltwater pump. And the ATO works fine when water change is not in progress. So my only problem is getting that new saltwater fill to work.

So far no one in north america seems to be able to get this to function. For now I'm using timers.
