SYSTEM FUNCTIONS WHISPER QUIET Not only are the Gree systems energy efficient but they are quiet too. Slim Duct operates with sound levels starting as low as 31 dB(A). MULTI FAN SPEEDS Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice of three different speeds (Low, Medium or High) to achieve maximum comfort.
SYSTEM FUNCTIONS INTELLIGENT DEFROST The Intelligent Defrost function increases room comfort and saves energy by eliminating unnecessary defrost cycles. In heating mode, the unit will monitor the outdoor coil for frost buildup. Once frost buildup has been detected, the system will switch into a defrost mode to remove the frost. I FEEL MODE In Cooling Mode, the unit will sense room temperature at the Tether Controller instead of at the indoor unit.
SYSTEM FUNCTIONS SLEEP MODE The unit will automatically adjust room temperature during your sleep time. This slight change in temperature will not affect your comfort level due to the natural effects that sleeping has on the body, but it will save on energy consumption and will lower electric bills.

ENERGY SAVING TIPS 1. Relaxing room temperature at night is OK: During the nighttime hours you don't require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy. 2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat. In winter, the sun is your friend.
