To Use the Sleep Feature:
To initiate, press the Sleep button . In this mode the selected temperature will increase
(cooling) or decrease (heating) by 2°F (1°C) 30 minutes after the mode is selected. The
temperature will then increase (cooling) or decrease (heating) by another 2°F (1°C) after an
additional 30 minutes. This new temperature will be maintained for 6 hours before it returns to

revert back to display the previous temperature setting or room temperature when the
unit is on. (Note-when the unit is off there is no display.)
