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 inefficient and leaky ductwork. The average
ducted air distribution system could reduce
overall system efficiency by up to 30 percent.
Eliminating ductwork allows you to downsize
equipment while upsizing performance.
