    FACTORY DEFAULTS - If, for any reason it is desirable to
    Return all stored settings back to the factory default
    Settings, press the Mode button. While holding the Mode
    Button in, press the Down button for 5 sec. All icons will
    Appear. Press and hold in the Fan button until Fd
    Appears. This resets all factory settings. To calibrate
    Room temperature, press the Mode button once more.
    At this point use the Up and Down buttons to calibrate
    Room temperature, if needed. Press the Mode button to
    Return to normal operation. NOTE CAUTION ON PAGE 1.


    Now read and use the rest of your manual. It is all in here.
