    Auto Water Change help

    So I am trying to set up a new auto water change system using 2 PMUP's. One to drain from the sump and the other to refill fresh SW from my SW container. I am not sure I am doing it correctly. Here is my programming:

    Auto Water Change virtual outlet:

    Fallback OFF
    Set OFF
    If DoW -----F- Then ON
    If Time 11:15 to 11:35 Then ON
    If ATK_Hi CLOSED Then OFF
    If Output RetPump_2_3 = OFF Then OFF
    If Leak CLOSED Then OFF

    PMUP Drain:

    Fallback OFF
    Set OFF
    If Output AutoWaterChg = ON Then ON
    If AWC_Lo OPEN Then OFF
    If Output LINKB_Refill = ON Then OFF
    Defer 010:00 Then OFF

    PMUP Refill:

    Fallback OFF
    Set OFF
    If Output AutoWaterChg = ON Then ON
    Defer 010:00 Then ON
    If ATK_Lo CLOSED Then OFF
    If ATK_Hi CLOSED Then OFF

    Thanks in advance for any help!

    If Time 11:15 to 11:16 Then ON
    If ATK_Hi CLOSED Then OFF
    If AWC_Lo OPEN Then OFF
    If Output RetPump_2_3 = OFF Then OFF
    Min Time 020:00 Then ON

    AllowDrain
    Set OFF
    If Output AutoWaterChg = ON Then ON
    If Output AllowFill = ON Then OFF
    If Leak CLOSED Then OFF

    AllowFill
    Set OFF
    If Output AutoWaterChg = ON Then ON
    Defer 010:00 Then ON
    If Leak CLOSED Then OFF


    PMUP Drain:

    Thanks! Where do I put the "AllowDrain" and "AllowFill" programming? Are they two separate virtual outlets?

    They are VOs.

    Worked perfectly! Thanks. One other question: why the "min time 20 then ON" for the AWC outlet? That's the only one that I don't quite get.

    That is so it only checks those conditions right before starting the drain sequence and forces the water change to finish if they activate during the change. The leak on the other hand will stop the water change mid sequence since it's in the allow VOs.
