    Help with DOS water changes and FMM program

    Hi I need help

    I have a DOS and ffm

    I would like the fmm to stop water changes when the water is below the sensor.

    my DOS heads are labeled OSW ( old salt Water ) and NSW ( new salt water )

    My sensor is labeled : Swx8_1

    it is closed when submerged and should turn off both OSW and NSW when it is open and out of the water

    Can someone please help me? how do I this??

    Hit the gear icon and go to the advanced tab. Add this to the code. I also suggest that you rename the opticals to something meaningful so it doesn't confuse you later.

    If Switchname OPEN Then OFF

    You might be an engineer if...You have no life and can prove it mathematically.

    No. Use the wizard for your water change. In the advanced tab add only these lines.

    If Swx8_1 OPEN Then OFF
    If DoW -MTW-FS Then OFF
