Unfortunately, I'm not sure your question really makes sense? Why would you need two ATOs?

Side note: I have two ATOs but it's for redundancy. They both do exactly the same thing. I don't think that's what you meant?

You could hook your RO/DI to a resevoir with a float valve and a pressure activated auto shutoff. You could then put the ATO pump in the resevoir.

A couple of things to keep in mind.
  • While it is rare, if the float valve fails you will have a flood.
  • This setup will cause premature failure of your RO membrane and you will go through a lot of DI resin. For your RO/DI to work properly, it needs to run for extended periods of time rather than on/off/on/off/etc
