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.

Precautions on air-outlet duct connection
• Connect the air-outlet duct to maximum 2 directions among the 4-duct connecting directions.
!
CAUTION
Do not connect ducts at 3 or more directions.
• When installing air-outlet duct in 2 directions, connect the ducts in a straight line.
• Once the ducted direction is decided, be sure to close the outlet in the direction.
Use optional Air outlet shutter plate (UTR-YDZK) to close the outlet.

• “Operation/Stop” mode or "Forced stop" mode can be selected with function setting of indoor unit.
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 150 m.
• The wire connection should be separate from the power cable line.
Indoor unit
Indoor unit functions such as Operation/Stop can be done by using indoor unit terminals.

Use either one of these types of terminals according to the application. (Both types of terminals
cannot be used simultaneously.)
• Dry contact
In case of internal power supply, set the slide switch of SW1 to "NON VOL" side.

NOTES:
• If the space is larger than stated above, the condition will be the same as when there is no
obstacle.
• Height above the floor level should be 50 mm or more.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation
efficiency.
!
CAUTION
• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and drain cap.
If the drain pipe and drain cap are used, the drain water in the pipe may freeze in extremely cold
climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it might
become difficult to get warm, and it is likely to cause product malfunction. Construct a canopy and
a pedestal, or place the unit on a high stand that is locally installed.
