New model
Power consumption
has been reduced
by 25% compared to
previous models by
using a compact and
high performance DC
fan motor.
High efciency
operation is
realized by
using a sine
wave DC
inverter control.
Signicantly
greater efciency
is realized by
use of a large
capacity DC twin
rotary compressor
with substantially
increased
refrigerant intake
and compression
ef ci ency.
Heat exchange ef ciency is signicantly
improved by the introduction of a new
4-face heat exchanger that increases
effective surface area.
In multiple outdoor unit installations, the
unique front intake design improves air ow
into the Heat exchanger.

Space saving and compact size
z
Compact size has been achieved by signicantly reducing the width of the outdoor units
compared to previous models.
Static pressure selection
z
5 Static Pressure modes are available.
Improvement and design exibility has allowed multiple fan speeds and static pressure modes.
The air ow rate has been improved to meet the requirements of complex ductwork layout designs. •
→ By introducing a new DC fan motor, the static pressure range selected by the installer can
range between 50 to 250Pa.
A three speed fan (High, Medium and Low) allows accurate airow control. •
A decrease in the power consumption of the indoor unit has been realised by optimizing the •
control of the indoor fan motor rotation frequency.

Outdoor unit quiet operation
z
Low noise mode (Optional parts: UTY-XWZXZ2)
Introduction of a low outdoor noise operation mode allow the outdoor unit to have two quiet mode
operation settings.
* Performance may drop depending on the outside air temperature condition, etc.
1) Level1 (Rated noise value -3dB)
2) Level2 (Rated noise value -5dB)
Peak cut operation
z
Peak cut mode (Optional parts: UTY-XWZXZ2)
The introduction of a peak power consumption mode control a 4 step outdoor operation control to
cut down energy usage at peak energy usage times.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... Performs operation which suppresses the power consumption to almost 0% by stopping
the compressor.
Level 2 ... Performs operation which suppresses the power consumption to 50% of the rated
power consumption value.
Level 3 ... Performs operation which suppresses the power consumption to 75% of the rated
power consumption value.
Level 4 ... Performs operation which suppresses the power consumption to the rated power
consumption value (100%).
