PRODUCT OVERVIEW

THE FUTURE OF ENVIRONMENTAL EFFICI EN CY

Feature-rich with advanced components, the Terra is our highest-efficiency model, specially designed to
save energy and protect the environment. Through our commitment to smart ecological design, the
Terra’s unrivalled technology packs an energy-efficient punch that is guaranteed to resonate well in any
atmosphere. This sleek heating and cooling device is a duct-fee wall mount heat pump system, equipped
with the latest G10 inverter technology and an intelligent energy saving function – up to 27 SEER. Sleek
and contemporary in appearance, the TERRA easily blends in with its surroundings and utilizes a highly
intuitive wireless remote control that aids in regulating room temperature with in-built I FEEL
automation. Our state-of-the-art Photocatalytic Filter and X-fan improves air quality by eliminating

99.9% of bacteria and viruses, while dually inhibiting mildew growth on its coil. Advanced efficiency
with refreshing ease, the Terra sustains long-term savings for you and the environment.

FEATURES AND BENEFITS

HIGH EFFICIENCY G-10 INVERTER - The G10 Invert er uses a broad range
of variable frequencies to drive the compressor, marking the highest level of
inverter control technology available today. Unlike conventional technology
that generally regulates room temperature by running at maximum capacity and
then shutting off completely, G10 Inverter technology eliminates these harsh starts/stops. This cutting
edge functionality results in quicker arrival at desired temperatures and superior maintenance of
consistent comfort levels. Higher efficiency and significant energy savings? Yes, it yields those too.

HEAT PUMP ADVANTAGE – Gree heat pumps, powered by the G10 Inverter, provide the same heating
capacity as electric heat, while using as little as 1/3 the electricity.

WHISPER QUIET - Not only is the Terra systems energy efficient, it’s quiet too. Wall mounted units
operate with sound levels starting as low as 23 dB(A).

INTELLIGENT DEFROST - The Intelligent Defrost function increases room comfort and saves energy
by eliminating unnecessary defrost cycles. In heating mode, the control system monitors the outdoor coil
for frost buildup, and the system switches to defrost mode only when frost buildup is actually detected.
This avoids unnecessary and wasteful defrosts.

FEATURES AND BENEFITS (Cont.)

GOLD FIN CONDENSER - The system’s co r r osion-resistant Gold Fin condenser
coating (1500hr salt spray rating) is made with a gold-colored anti-corrosion epoxy.
This technology maintains excellent heat transfer properties while extending coil life
against damage from salt air and salt water in seacoast installations.

LOW VOLTAGE START UP – Having stable electrical power is not always an option. The Gree system
will operate from 170v to 253v (230v model) and 104v to 127v (115v models) which is suitable for
unstable power supply areas.

SUBTLE APPEARANCE -Designed for a comfortable fit in virtually any living space. This slim
compact cabinet sits inconspicuously on the wall, and blends into most interior designs.

UNIT DISPLAY – Terra wall mounted units have a large easy-to-read display and indicator lights giving
instead feedback on room setpoint, operating mode and much more. The display can also be turned off
based on your personal preference.

MULTI-SPEED FAN – The indoor fan can run at up to four different speeds (Low, Medium, High or
Turbo) for either COOLING or HEATING mode for maximum comfort and quiet operation.

TIME GUARD - Among the system’s many safeti es is a Time Guard function to prevent rapid cycling of
the compressor. A protective five-minute time delay restricts compressor restarts after shu toff.

POWER FAILURE MODE - Power interruptions are no problem. User sel ections and system parameters
are stored in non-volatile memory. These parameters are retained during a power failure. When power is
returned, the system will automatically return to the last operating mode.

INTELLIGENT PRE-HEATING - The system guards against the annoying COLD BLOW in heating
mode, and 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.

POLYMERIC AIR FILTERS –Two-piece removable polymeric air filters easi ly slide in and out from the
front of the indoor unit and are interchangeable. The front panel does not need to be removed to access or
change the filters. The filters are washable and permanent.

PHOTOCATALYTIC FILTER – Photocatalytic Air Filter is a second stage filter that oxidizes and
effectively eradicates organic contaminants in the air. This hi-tech filter uses natural ultraviolet light with
a titanium dioxide catalyst to effectively eliminate 99.9% of bacteria and viruses and absorb odors for
healthier indoor air.

FEATURES AND BENEFITS (Cont.)

COMMAND CENTER–The unit comes with a factory supplied wired Tether Controller or Wireless
Remote Controller.

Note: the controllers are mutually exclusive. They cannot be used at the same time.

WIRELESS IR REMOTE CONTROLLER - The Gree multi-functional infrared hand held
wireless controller is sleek, ergonomically designed, easy to use and has a large backlit L CD
display.

WIRED TETHER CONTROLLER (Optional) – The Gree tether controller mounts to the wall up
to 25 feet from the unit. It provides complete control over operation mode, desired temperature,
fan speed, airflow direction and more.

MODE BUTTON - The units can be set to five different operating modes: HEAT, COOL, DRY, FAN
ONLY and AUTO.

Note: AUTO MODE has fixed setpoints of 68° F heating and 78° F cooling, which are not
changeable. The system will automatically select heating or cooling to maintain room
temperature within this temperature band.

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

I FEEL MODE – The unit will sense room temperature at the remote controller instead of at the indoor
unit. It then adjusts airflow and temperature accordingly for the ultimate in personal comfort control and
energy savings.

SWING LOUVER –The Terra systems provides four-way airflow control for optimal temperature cont rol
and the ultimate in comfort. The indoor units have adjustable horizontal and vertical Swing Louvers to
maximize room comfort. The Swing Louvers can be set in multiple different air discharge directions
including continuous sweep from the Wireless IR or Wired Tether Controllers.

PRIVACY LOCK MODE – Both wired tether and wireless controllers have a Privacy Lock to avert
unauthorized access and stop tampering wit h system settings.

SLEEP MODE –Terra system provide three Sleep Modes to 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.

QUEIT MODE – Terra’s QUIET MODE function delivers quiet comfort to your room. In heating or
cooling mode, the indoor unit operates normally for the first ten (10) minutes or until room setpoint
temperature is reached. Then the Terra system will operate quietly at low fan speed

FEATURES AND BENEFITS (Cont.)

ENERGY SAVING MODE – Energy Saving mode will automatically select the optimal fan speed t o
saves energy while operating in Cooling and Heating modes. The fan will automatically slow down the
closer the room temperature is to the setpoi nt.

FAHRENHEIT ° F / CELSIUS ° C - The wired tether and wireless controllers can be set to display in
either °F or °C.

SELF-DIAGNOSIS –With an on-board computer using real-time diagnostics, the Gree system helps to
prolong its own life. The automatic diagnosis feature continuously scans for unacceptable operating
conditions or malfunctions. If such conditions occur, the system takes corrective action or stops. Fault
codes are shown on the unit display to facilitate easy troubleshooting and repair.

AGENCY LISTINGS - All systems are listed with
AHRI (Air conditioning, Heating, and Refrigeration
Institute) and are ETL Certified per UL Standards.

5/7 YEAR LIMITED WARRANTY - Enjoy one of the most comprehensive warranties in the industry.
