PRODUCT OVERVIEW

SUPERIOR DESIGNS PROVIDE EASY SOLUTIONS TO COMPLEX PROBLEMS

GREE Ductless Multi Zone systems provide quiet comfort and energy ecient heating and cooling in up to

ﬁve dierent rooms – without ductwork. For most residential and light commercial applications, this is the ideal

solution to balance comfort, eciency and ease of installation. This Inverter-driven system oers Seasonal

Energy Eciency Ratings (SEER) up to 16. With individual room control and variable speed compressor

operation, comfort is boosted throughout your home or oce, 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-eective. 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 eciency 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 inecient and leaky ductwork. The average

ducted air distribution system could reduce

overall system eciency by up to 30 percent.

Eliminating ductwork allows you to downsize

equipment while upsizing performance.

High Eciency G-10 Inverter

The G-10 Inverter 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 o

completely, G-10 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 eciency and signiﬁcant energy savings? Yes, it yields those too.

Heat Pump Advantage

Multi Zone heat pumps, powered by the G-10 Inverter, provide the same heating capacity as electric

heat, while using as little as 1/3 the electricity.

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.

Time Guard

Among the system’s many safeties is a Time Guard function to prevent rapid cycling of the compressor.

A protective three-minute time delay restricts compressor restarts after shuto.

Gold Fin Condenser

The system’s corrosion-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.

+Multi Outdoor Units

Each +Multi heat pump is powered by Gree’s energy ecient G-10 Inverter and a variable speed compressor. These units can

heat and cool up to ﬁve zones without distribution boxes, and all oer the G-10 advantages of energy savings, noise reduction

and room temperature consistency. Each outdoor coil also features a corrosion-resistant Gold Fin coating to withstand corrosive

environments and to further promote energy eciency.

FEATURES AND BENEFITS

Low Voltage Start Up

Having stable electrical power is not always an option. The Gree Multi Zone units will operate from

170v to 265v which is suitable for unstable power supply areas.

Self-Diagnosis

With an on-board computer using real-time diagnostics, the Gree Multi Zone 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 standards.

7/5 Year Limited Warranty

Enjoy one of the most comprehensive warranties in the industry. Seven (7) years

on compressor and Five (5) years on all parts.
