    Default Simple ATO failsafe logic: Turn off if alarm

    So I'm having trouble figuring out really what logic gate to use to turn off ATO socket if salinity alarm is active.

    Which function to use so that IF there is a salinity alarm the socket will not activate? Trouble I see here is that input level 1 could either be on or off.

    I'm missing how to set it so that anytime salinity alarm = yes ATO socket is always off.

    Default

    I figured it out!

    G1 =
    input Salinity (alarm) -> INVERTED
    AND
    input ATO1
