    Water change automation with PMUP this

    I have an idea of using two PMUPs for doing a water change.

    One pump would be placed in the sump and the other in the water reservoir. The pumps would cycle using the level sensors of the ATK to control each pump.



    The process would start with the reservoir pump activating until the ATK high level sensor activated.

    At this point the reservoir pump stops, a 5 second pause then the sump pump would start until the ATK low sensor opens.

    At this point the sump pump stops a small pause again and then the reservoir pump would start.

    This cycle would continue until the reservoir was empty.

    So so all you APEX programming geniuses...

    Help.

    Before getting into programming, you need to clear some hurdles about proper installation.

    1. How do you plan on breaking siphon?

    2. How do you plan on detecting that the reservoir is actually empty?

    You would do something along these lines. Placement is key for the siphon break.

    EnableWC
    Set OFF
    If LowRes CLOSED Then ON
    If Error NSW Then OFF
    If Error OSW Then OFF
    If Salt > 36.0 Then OFF
    If Salt < 34.0 Then OFF

    NSW
    If ATOlow OPEN Then ON
    If ATOhigh CLOSED Then OFF
    If Output EnableWC = OFF Then OFF
    When On > 002:00 Then OFF

    OSW
    If ATOhigh CLOSED Then ON
    If ATOlow OPEN Then OFF
    If Output EnableWC = OFF Then OFF
    When On > 002:00 Then OFF
