PRODUCT OVERVIEW
SUPERIOR DESIGNS PROVIDE EASY SOLUTIONS TO COMPLEX PROBLEMS
GREE Ductless Multi Zone systems provide quiet comfort and energy ecient heating and cooling in up to
five dierent rooms – without ductwork. For most residential and light commercial applications, this is the ideal
solution to balance comfort, eciency and ease of installation. This Inverter-driven system oers Seasonal
Energy Eciency Ratings (SEER) up to 16. With individual room control and variable speed compressor
operation, comfort is boosted throughout your home or oce, while utility bills are held in check.
Gree’s exclusive G-10 Inverter technology powers the twin rotary compressor inside the Multi Zone
outdoor compressor section. The G-10 Inverter constantly adjusts the compressor speed to maintain
a comfortable room temperature. This saves energy, reduces outdoor noise and maintains a steady
room temperature by eliminating the harsh starts and stops of conventional systems.
When laying out a new project, you’ll appreciate the flexibility of Gree’s Multi Zone Systems. A single outdoor unit
can simultaneously power up to five indoor units while eliminating expensive ductwork. Without those ducts, your
installation is simpler, faster and more cost-eective. And the flexibility doesn’t stop there, as you can also mix
and match your choice of Wall Mount, Ceiling Cassette, Concealed Duct, Universal Floor/Ceiling and Mini Floor
Console indoor units to create a unique heating and cooling system to perfectly fit any project.
No pipe sweating
No sweating is needed for the pipe connection
between the indoor and outdoor units. All
piping connections are flared to simplify and
ease the piping installation.
Simple Wiring
No special or hard-to-find communication
wire is needed between the indoor and
outdoor units. The system uses common
14-4 AWG stranded copper THHN 600V
wire. The system’s communication is ready
as soon as the electrical wiring between the
indoor and outdoor units is complete.
High Lift Design
Gree’s High Lift design allows for extended
piping length, up to 262 feet total, as well as
50 feet of vertical lift from the condensing
units. This allows for greater flexibility in the
layout of the system.

Energy Saving
Multi Zone systems allow each room to be individually controlled. Only those rooms requiring air
conditioning (or heating) are cooled (or heated), and all of it is accomplished without ductwork.
In addition, Gree’s G-10 inverter technology reduces energy waste, maximizes eciency and
achieves up to 16 SEER.

PRODUCT OVERVIEW
Self-Diagnostics System
Each indoor and outdoor unit continuously runs
a series of multi-point diagnostic tests on the
system, to automatically scan for unacceptable
operating conditions or malfunctions. If such
conditions occur, the system takes corrective
action or stops. The fault code will be shown
on the indoor, outdoor and wired controller displays.
Problems and system status are displayed with
comprehensive diagnostic codes to simplify system
troubleshooting and shorten repair times.
Flexible Design
Gree’s Multi Zone systems have many advantages
for both the property owner and the installer.
Up to five indoor units, powered by a single
outdoor unit, results in flexible zoning solutions
for almost any application. Various styles of
indoor units may be mixed and matched in any
combination to create a unique, multiple zone
heating and cooling system. Choose from Wall
Mount, Ceiling Cassette, Slim Duct, Universal
Floor/Ceiling and Mini Floor Console indoor units.
All are lightweight and compact enough to be
installed on the wall or in any ceiling space.

Intelligent Control
Gree’s Multi Zone components use state-of-the
art intelligent controls to generate the ultimate
in room comfort. G-10 Inverter technology
delivers the exact level of required capacity (from
10% to 100%) to maintain room temperature and
humidity in the comfort range. The optimized PID
controls maintain the room temperature within
less than ±1.0°F of the room setpoint temperature.
The result is a virtually constant room temperature
without the typical fluctuations that occur with a
conventional fixed speed ON/OFF system.
Ductless Saves Money
Realize energy savings by eliminating heat loss
from inecient and leaky ductwork. The average
ducted air distribution system could reduce
overall system eciency by up to 30 percent.
Eliminating ductwork allows you to downsize
equipment while upsizing performance.

FEATURES AND BENEFITS
Command Center (cont.)
Fan Speed
The system fan speed (High, Medium, Low or Auto) can be adjusted for peak room comfort
and quietness.
Room Setpoint
The XK series makes dialing in the correct room setpoint temperature a breeze. Most indoor
units allow a room setpoint from 61° F to 86° F (16° to 30° C).
Timer Mode
When needed, the XK series allows you the ability to program a time period (one-half to
24 hours) to which your system will automatically turn ON or OFF.
Sleep Mode
The XK series will automatically adjust room temperature during your sleep time. This slight
change in temperature will not aect your comfort level due to the natural eects that
sleeping has on the body, but it will save on energy consumption and will lower electric bills.
Turbo Mode
Whether you need to heat up or cool down a room quickly, Turbo Mode will force your system
to run at higher speeds to reach the desired room temperature faster.
X-Fan Mode
The X-Fan function can be activated from the XK series to remove moisture buildup when the
system is turned OFF. This helps prevent mold and mildew growth on your indoor coil and fan.
Privacy Lock
The XK series has a Privacy Lock that can be set to prevent unauthorized access to the unit
controls and prevents tampering with system settings.

conditions or malfunctions. If such conditions occur, the system takes corrective action or
stops. The fault or status codes will be shown on XK series wired tether controller display
to facilitate easy troubleshooting and repair.
