    Help: Need LDK To Shut Off DOS

    Hello,

    Can someone help me with this programming issue. It seems so simple, but its not working.

    I would like my LDK to shut off my DOS which I use for water changes.

    The DOS is always set to OFF. When I'm ready to do a water change every couple of weeks I set the DOS to AUTO. When the water change is complete I set it back to OFF.

    The LDK works and sends a notification, but it is not shutting the DOS OFF. Below is my programming for the DOS. I also assume the programming must go into both pump 1 and pump 2 of the DOS?

    Set OFF
    If 5_Leak CLOSED Then OFF

    Am I missing something because the DOS is not always ON? What would the programming be for AUTO?

    Your help is greatly appreciated!!!

    Thanks!!!!

    Then I would do this. Create a VO

    StartWC
    Set ON
    If 5_Leak CLOSED Then OFF
    When On > 540:00 Then OFF

    In the DOS replace what you have in advanced tab with

    If Output StartWC = OFF Then OFF

    When you want to do a water change set it to AUTO and it will automatically shut off if a leak sensor is tripped and will automatically go to manual OFF after 9 hours.

    Thanks for your help!!

    I have the VO setup, but is this correct?

    Fallback 0 (It says: Send Failed//Error: line 1 - Statement must start with If, OSC, Min, Set, Fallback // StartWC If I Copy and paste what you put)
    Set ON
    If 5_Leak CLOSED Then OFF
    When On > 540:00 Then OFF

    I'm encountering this in the DOS advanced tab:

    Send Failed

    //Error: line 3 - Valid keywords following If are Temp, pH, ORP, DO, Cond, Salt, Par, Feed, SwX, FLx, Error, Power, Sun, or Moon // If Leak_Program StartWC = OFF Then OFF

    A virtual outlet should not have a fallback state.

    The DOS advanced issue is because your name is wrong. It needs to be

    If Output VOname = OFF Then OFF

    Not

    If Leak_Program StartWC
