See my last post. and this blog - the app works with F200 series as well. You just need the IVC -6 or ICV-6 controller (which is 49$)It does look like the new controllers could do what I want, but that would be a $1k upgrade as opposed to what should just be a fairly simple software change.
I also like that I can turn them off when I put my tank in maintenance mode and that if I forget to restart them, they do automatically after 1.5 hours. Being able to push one button on a touch screen to make my system go from running to ready for a water change is a very nice feature that I would lose even with the new controllers.
