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.

No need for the flow sensor, you're only needing to read the water level in the sump and shut it off with the solenoid valve. The FMM module is needed if you have the older Apex unit that does not have it built in, the A3 models all have that already unless you've used up all the available ports.

Excellent. Thank you.

I now have the solenoid and the optical sensor set up. Used the wizard to program it, but it's not working. Any idea what could be wrong with the setup?

Not working as in not turning off? Or not turning on.

RO is not kicking on even when the solenoid is on. The code seemed to work. For example, when the high water level was reached the optical sensor closed and so did the solenoid. But when it was open, no RO was dripping into the sump. It's hooked up inline between float valve and RO output.
