SYSTEM FUNCTIONS

WHISPER QUIET

Not only are the GREE systems energy efficient but they are quiet too. Slim Duct B Series units operate with sound pressure levels starting as low as 25 dB(A).

MULTI FAN SPEEDS

Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice of fan speed plus Turbo to achieve maximum comfort.

INTELLIGENT PREHEATING

This system guards against the annoying cool air blown into the room in heating mode. The system constantly monitors the discharge air temperature. It will delay the indoor fan until the indoor coil has warmed up to prevent blowing uncomfortable cool air into the room.

I-FEEL FUNCTION

The unit will sense room temperature at the remote controller instead of at the indoor unit. It then adjusts airflow and temperature accordingly for ultimate personal comfort.

TURBO MODE

Use Turbo Mode for situations where you wish to achieve the desired room temperature in the shortest possible time. This mode runs the unit at ultra high speeds for quickest results.

VACATION MODE (FREEZE GUARD)

Vacation mode (freeze guard) sets the unit to 46^ F ( 8^ C) in heating to keep the temperature in the space above freezing.

TIMER MODE

The unit can be programmed to turn ON or OFF after a specific amount of time. The time period is adjustable between one half and 24 hours.

MODE BUTTON

The unit can be set to five different operating modes: HEAT COOL, DRY, FAN ONLY and AUTO.

SLEEP MODE

The system offers a Sleep Mode function for your comfort. 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 SAVINGS MODE

This feature will automatically select the optimal compressor and fan speeds to allow for energy savings while operating in Cooling or Heating modes. The compressor and fan will automatically slow down as the room temperature reaches the set point.

SELF-DIAGNOSIS

The system has a built-in computer which uses real-time diagnostics which help prolong the unit's life. The automatic diagnosis feature continuously scans for errors or malfunctions and fault codes are shown on the unit display to facilitate troubleshooting and repair.

POWER FAILURE MODE

Power interruptions are no problem for this system. User selections and system parameters are stored in non-volatile memory. These parameters are retained during a power failure. When power is returned, the Slim Duct B Series system will automatically return to the last operating mode.

INTELLIGENT DEFROST

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 build up. Once frost buildup has been detected, the system will switch into a defrost mode to remove the frost.

The remote controller and wired controller can be set to display in either °F or °C.

REMOTE LOCK-OUT

The remote controller has a Lock feature. The Lock averts unauthorized access or tampering with system settings.

AGENCY LISTINGS

All systems are listed with AHRI (Air Conditioning, Heating, and Refrigeration Institute) and are ETL certified per UL Standards.

ENERGY SAVING TIPS

1. Reduce room setpoint at night: During the night 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, it is recommended 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. Open curtains and shades to allow solar heat into your room.
3. Close doors: If you don't need to heat and cool your whole home, confine the heating and cooling to one room by closing doors.
4. Service the unit: Some basic maintenance might be all you need. The outdoor unit will greatly benefit from a good hosing off, leaves, grass clippings and other debris can stick to coil fins and make the unit work up to 15% harder!
5. Rearrange the room: Furniture that obstructs the airflow, needs to be removed or rearranged accordingly.
6. Try 75 degrees: 75^ is a good point for an air conditioner to run at its optimal performance level. Even a 5-degree change in temperature can make your unit use up to 40% more energy.
7. Lighting: Turning lights off can help reduce your heat. Each light bulb is a tiny heater. Your air conditioner must waste energy overcoming the heat from your lights to reach and hold your desired room temperature.
8. Zero occupancy: During zero occupancy turn your unit to Auto mode and make sure windows and curtains are closed. Although room temperature may be less than optimal for a few minutes when you return, the unit will soon have the room back to your desired temperature.
9. Don't forget the fan: The fan is much like a car. The faster it runs, the more energy it uses. Try saving money by using the comfortable quiet low fan speed as much as possible.
