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.

+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

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.

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.
