I have been wanting to use one for the same thing. From what I know of at the moment they don't have anything out to sense the levels. But they have something in the works for the future. I am hoping that future part comes soon. But we will see.
For the time being you would need to have a controllable outlet of some kind (through another controller like the apex or the Autoaqua Smart Level). Then run the Versa in continuous mode so that it pumps at a constant speed whenever the outlet kicks it on.
I’ll second what everyone else has said so far, or you can figure out your evaporation rate. If you want, I have my Versa set as an ATO and explain how I did it in my build thread.
