    RO Booster pump programming help

    I am doing something wrong and I can't figure it out. I'd like the RO solenoid and the booster pump to turn off when the optical sensor is closed. The programming:

    Solenoid:
    Fallback OFF
    Set OFF
    If sensor OPEN Then ON

    Booster:
    Fallback OFF
    If sensor OPEN Then ON

    The sensor does work (it closes when it's covered by water) but the pump/solenoid doesn't turn off.

    The programming looks too simple so I think I'm missing something.

    Thanks!

    You do not have anything to turn OFF the Booster outlet. You are missing the Set OFF (Highlighted below)

    Booster:
    Fallback OFF
    Set OFF
    If sensor OPEN Then ON

    Thanks, Jon. It works now.

    I had that command in there and it didn't work so I removed it based on another thread to try it out. I must have done something in between then and adding it back. Seems to be okay now.
