Apex Float Switch Program

[ithk21620]

I am trying to program my apex so that when my “RO_LOW” float switch is triggered it will turn on my “Make_RO” outlet for X amount of time.

Right now I have a float switch in my RO container and when it gets triggered I get an alarm. I then go into my apex and turn on a VO (Make_RO) that turns on my RO unit but I would like to automate this since I typically forget to go back and turn it off. I do have a float valve in the tank that will turn the RO off with the pressure switch and such so it’s not a big deal when I do this but I would prefer to have the apex shut the system off as well for redundancy.

I understand the normal apex programming like:

Set Off
If RO_Low is OPEN the ON

I just don’t fully understand the Defer or Min programming that I think I need to get the outlet to turn off after “X” amount of time and then stay off until the float switch is triggered again.

I use a pair of floats to trigger filling of my ATO reservoir.

FALLBACK OFF
IF ATO_LO CLOSED Then ON
DEFER 005:00 Then ON
IF ATO_HI CLOSED Then OFF
DEFER 005:00 Then OFF

ATO_LO triggers the RODI, but since there is no SET command, there is nothing to turn off the RODI until the ATO_HI is triggered. Works pretty well.
