Understanding ATO setup on Apex

[Mr.BobDobalina]

I have my RODI plumbed directly to the float valve in my sump. I would like to be able to have something besides the float valve to trigger the RODI unit to turn off when the sump is full. So I am thinking I need a FMM module, solenoid valve, 1/4" flow sensor and optical sensor to make this happen with the Apex? I would plug the FMM into the EB832 and connect the solenoid and both sensors to the FMM. If the water reaches the level of the sensor it will trigger the RODI to turn off, yes? I am trying to wrap my head around it so if you have advice, Id appreciate it.
