Advancement in comfort
Quiet operation
Individual airflow provides free air conditioning
• Individual airflow can be controlled by wired remote controller.
• Individual airflow also can be controlled in any positions.
Wide airflow achieved quick air conditioning around all direc-
tions
• New wide louver can provide more airflow.
• The louver design distributes airflow at the corner.
• Uniform temperature air conditioning by airflow
Case study:
Comfortable air conditioning
by draft prevention and
swing air blow.
Efficient air conditioning
based on the room layout.

NOTES:
Specifications are based on the following conditions:
–Cooling: Indoor temperature of 27 °CDB/19 °CWB, and outdoor temperature of 35 °CDB/24 °CWB.
–Heating: Indoor temperature of 20 °CDB/15 °CWB, and outdoor temperature of 7 °CDB/6 °CWB.
–Pipe length: 5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)
Protective function might work when using it outside the operation range.
*1: Maximum current:
–The maximum value when operated within the operation range.
–The total current of indoor unit and outdoor unit.
*2: Sound pressure level:
–Measured values in manufacturer’s anechoic chamber.
–Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.

For 3-direction setting:
NOTES:
• To set “3-direction”, optional Air outlet shutter plate (UTR-YDZK) must be installed, and the
“outlet-direction” need to be switched to “3-way” by remote controller.
• The ceiling height cannot be set in the 3-way outlet mode. Therefore, ceiling height setting change
by function setting 20 is prohibited. For details, refer to “Contents of function setting” on page 69.
Human sensor(Option)
Example of sensitivity range:
When the installation height gets higher, the temperature sensitivity decreases.
!
CAUTION
Do not place large objects near the human sensor. Also keep heating units outside the sensor’s
detection area.
