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.
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.
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
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.

The main power is supplied to the outdoor unit. System must be on a single dedicated circuit.
Use appropriate wire size and circuit breaker (or fuse) size for proper system overcurrent
protection. Follow all local building codes and NEC (National Electrical Code) regulations.
Interconnecting Cable Wiring Diagram
The indoor unit is powered by the outdoor unit. The interconnecting cable between the outdoor
and indoor unit must be a 14/4 AWG stranded copper conductors THHN 600V unshielded wire.
The interconnecting cable should not be buried underground and must be recognized by UL or
ETL and CSA certified.
Note: Use shield cable if installation is in close proximity of RF and EMI transmitting devices.
Local codes may require a disconnect switch within sight of the indoor unit. For these
installations, use a DFS Disconnect Switch Accessory Kit (Part No: DFS-SWITCH-A) to break
wires going to the N(1), 2, 3 terminals on the indoor unit, as shown in the wiring diagram below:

CONDENSATE REMAOVAL
Install condensate drain to safely and effectively route condensate water to a safe location. Use a flexible
condensate drain hose to fit over the factory 5/8-inch (16mm) drainage port. The high wall indoor units
have an internal condensate trap. Adding an ext ernal trap is not required.
All condensate drains must meet local codes and reg ulations. If adequate gravity drainage cannot be
provided, a field-installed condensate pump m ust be used. Refer to manufacturer’s installation
instructions, specifications and operating details supplied with cond ensate pump.
