    I want my ATO pump to stay on for a minute at least.

    Is there a line I can add to keep the pump from turning on and off real quickly? I’d like it to stay on for a minute or off for a minute once it changes.

    Fallback OFF
    If pH_Tan > 8.05 Then OFF
    If pH_Tan < 8.02 Then ON
    If Float OPEN Then OFF


    I’m sure I can use it for my co2 selonoid program too.

    That's what the min time command is for. You will need in for on and one for off

    Min Time 001:00 Then ON
    Min Time 001:00 Then OFF

    You might be an engineer if...You have no life and can prove it mathematically.

    Thanks! I ended up searching min time and found defer. I used defer but is that an advantage to using min time?

    Fallback OFF
    If pH_Tan > 8.05 Then OFF
    If pH_Tan < 8.02 Then ON
    If Float OPEN Then OFF
    Defer 001:00 Then ON

    Defer means wait an extra 1 minute after the outlet would otherwise change state.

    Min Time means turn ON/OFF for at least 1 minute.


    Depends on which suits tour preferences for the application.

    More info on both min time and defer can be found in the reference manual. You can download it from the Neptune links at the top of the page.
