    ATO and min time

    I'm likely missing something really easy, but I have a question on my ATO. The delay works just fine to avoid the ATO turning on until the sump_low float stays in an on state for 5 minutes. However, I have it set (or rather trying to set) a min time of 10 minutes. This part is not working and the ATO pump turns off the moment the sump_low goes to an off state instead of running an additional 10 minutes. Thanks!

    Fallback OFF
    Set OFF
    If Output Sump_Low = ON Then ON
    If Output Sump_High = ON Then OFF
    Defer 005:00 Then ON
    Min Time 010:00 Then OFF

    Yeah, Min Time works opposite to what you want. It means, when set to OFF, stay OFF for 10 minutes regardless of any command to turn it back ON. It helps to mentally ignore the 'Then'. You want to use Defer 010:00 Then OFF instead.

    Ok, that makes sense. Can there be two defer statements then? A defer on as well as the defer off?

    Thanks!!

    Edit: The "Sump_low" is a virtual outlet so I could always put the defer on in there, then use defer off on the pump programming. If two defer statements works though that would be easier. I'd run to simply test it but had to move to the office already

    Yes. You can use two min time or defer as long as one is ON and the other is OFF.
