    Keyboard Lock-Out
    You can lock the Infinity
    Control buttons to help avoid inadvertent
    changes to your settings.
    Keyboard lock-out can ONLY be activated from the main screen.
    To do so, simultaneously press the ZONE and FAN buttons for two
    seconds. Keyboard lock-out will be indicated by a graphic lock on
    the screen.
    To unlock the control, simultaneously press the ZONE and FAN

    buttons for two seconds.

    That's to lock and unlock it. Not sure if you can actually disable the feature. Check inside the stat to see if there is a removable jumper labelled "lock".
