SYSTEM FUNCTIONS

WHISPER QUIET
Not only are the GREE systems energy efficient but they are quiet too. 3VIR High-Wall units operate with sound pressure levels starting as low as 20 dB(A).
MULTI FAN SPEEDS
Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice of seven fan speed plus Turbo to achieve maximum comfort.
INTELLIGENT PREHEATING
The 3VIR 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.
ADJUSTABLE AIRFLOW
The 3VIR system has a bi-directional airflow control for maximum comfort. The indoor unit has adjustable vertical and horizontal swing louvers and can be set in multiple discharge directions from the wireless remote controller.
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) set’s 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 3VIR 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
Your 3VIR 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 the 3VIR system. User selections and system parameters are stored in nonvolatile memory. These parameters are retained during a power failure. When power is returned, the 3VIR system will automatically return to the last operating mode.
INTELLIGENT DEFROST
The 3VIR 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.
WASHABLE POLYMERIC AIR FILTER
The polymeric mesh filters save energy by preventing the indoor coils from being plugged with dirt and lint. This economical and sturdy filter may be washed, vacuumed and reused.
FAHRENHEIT / CELSIUS
The remote controller and indoor wall unit front panel can be set to display in either °F or °C.
REMOTE LOCK-OUT
The wireless 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.

WARNING

•  When the following occurs, turn the unit off and disconnect power immediately, contact your installing contractor or a licensed HVAC technician.
  • Power supply wiring is overheating or damaged.
  • There’s abnormal sound during operation.
  • Circuit breaker trips off frequently.
  • Air conditioner gives off burning smell.
  • Indoor unit is leaking.

•  Do not try to service or repair the unit yourself.

•  If the unit operates abnormally it may cause internal or external damage, electric shock or become a fire hazard.

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! Rearrange the room: Furniture that obstructs the airflow, needs to be removed or rearranged accordingly.
5.  Try 75 degrees: 75°F 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.
6. 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.
7. 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.
8. 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.
