    Help with PMUP programming.

    Help with PMUP programming.
    I am trying to use the PMUP to send water from my RODI holding container to my auto top off reservoir.
    I have the Apex Classic and using 2 FMM modules, Breakout Box, and the PMUP in the setup.
    I have searched the forums and found similar programming however, I am missing a step as the programming is not working how I would like it to work.
    Here is my programming:

    Fallback OFF
    Set OFF
    If ATOBot OPEN Then ON
    If ATOTOP CLOSED Then OFF
    When On > 005:00 Then OFF
    Defer 000:10 Then ON
    Defer 000:04 Then OFF
    Min Time 060:00 Then OFF

    The PMUP is using the 24vDC port in one of the FMM modules.
    The ATOBot is a float sensor wired into the breakout box to determine when the water level is low in my ATO reservoir.
    The ATOTOP is an optical eye plugged into the 2nd FMM module and is used to determine when the water level in my ATO reservoir is full.

    Scenario:
    ATOBot changes to open status and the PMUP turns on and begins to pump water into my ATO. However once the float changes to closed status the PMUP turns off.
    How do I get the PMUP to continue adding water to my ATO until it reaches full status and the ATOTOP sensor changes to closed?

    This is the first time I have posted a question, hopefully I have included all the necessary information. I have utilized the forum for quite some time and have learned a lot.
    Thank you for any assistance.

    Remove the Set Off line. That is what is turning it off as soon as ATOBot closes. You want to let the ATOTop command change it to off rather than forcing it to off every time the programing is evaluated.

    The ATOBot will always shut off the PMUP.

    I have a similar function to fill my ATO reservoir. I don't use ATOBot to start my PMUP. I set an interval to check to see if my reservoir is low (in my case once an hour) and then fill it until ATOTOP is closed. I only let the PMUP run for a couple of minutes per hour. So it fills up the reservoir a little each hour. You could do whatever you like, for example check every other day, let it run for 60 minutes, etc. Here is a code fragment, you can add more to it.

    ATOFILL
    Fallback OFF
    Set OFF
    OSC 000:00/002:00/058:00 Then ON
    If Output ATOTOP = CLOSED Then OFF
    If Output RODIBot = CLOSED Then OFF

    I also have a Optical Sensor in my RODI holding container, So ATOFILL never happens if the RODI holding container is empty.
