    Help with FMM needed

    Hi
    I have a flow sensor that is connected to my chiller, what will the code be to switch off the chiller if the flow drops so that I do not burn out my chiller

    Do you want it to latch off until you manually reset it, automatically retry after some time has passed, or automatically reset if flow goes back within range? Do you intend to shut the pump off too, or just the chiller?

    I would like it to automatically reset after some time once the flow has returned to its normall range. I would like the chiller to shut down so that it dose not burn out and the pump to also be off.

    Then you would want something in this form. This example assumes 200 gph is "normal" for the chiller, and will automatically retry after 2 hours and send you hourly alerts while its activated.

    LowChillFlow
    Set OFF
    If Flow < 150 Then ON
    If Output FeedPump = OFF Then OFF
    Defer 000:10 Then ON
    Min Time 120:00 Then ON

    FeedPump
    (Existing code)
    If Output LowChillFlow = ON Then OFF

    Chiller
    (Existing code)
    If Output LowChillFlow = ON Then OFF

    Email
    (Existing code)
    If Output LowChillFlow = ON Then ON
