    Anybody know how to unlock a prog. zone sensor. It's on a trane 20 ton gas pak. The screen has a lock in the lower left corner. I can't get it to do anything. Sorry for the double post.
    Please step AWAY from the condensing unit.

    Press the "plus" and "minus" keys simultaneously and hold for 4 seconds. Repeat to re-lock key pad.
