setting when no one is occupying the room. Energy Saving function is
on at the time of purchase.
1 To activate the Energy Saving function, press the "SENSOR"
button.
"ENERGY SAVING" indicator on the remote controller will blink.
2 To deactivate the Energy Saving function, press the "SENSOR"
button again.
"ENERGY SAVING" indicator on the remote controller will turn
off.
About the Energy Saving Function
If no one enters the room for approximately 20 minutes, the set
temperature will be automatically controlled.
(When someone comes back into the room, the human sensor will
detect this, and automatically revert to the original settings.)
Operation
mode
Operating details
(if there is no one in the room for a while)
Cooling/Dry The set temperature will be increased by a maximum of
approximately 2˚C.
Heating The set temperature will be decreased by a maximum
of approximately 4˚C.
Auto This runs the Energy Saving function automatically for
the selected mode (Cooling/ Heating/ Dry).
● When using together with the Sleep timer (page 6), the Sleep
timer will be prioritized.
● During the 10°C Heat operation, if there is no one in the room the
set temperature will not be changed.
● Application range is as follows.
Vertical angle 90° (Side view) Horizontal angle 100° (Top view)
6 m
6 m 90° 50° 50°
Energy Saving function may not work when the room temperature is
very different from the temperature dened in temperature setting, such
as when immediately after starting the operation.
About the HUMAN SENSOR
Details about detection with the human sensor
● The human sensor detects whether there are people in the room
by looking for movement by people in the room.
Since the human sensor detects infrared light given out by
people, there may be cases where this detection is incorrect.
Situations in which the sensor will detect no people in the
room, even when there is someone there
When the temperature is high and the difference with be-
tween people’s body temperature is small.
(Such as during the summer when the temperature is 30°C
or higher.)
When there is someone in the room, but they do not move
for a long period of time.
When someone is hidden behind a sofa, other furniture,
glass, or in similar situations.
When someone is wearing extremely thick clothing and has
their back facing the sensor.
Situations in which the sensor will incorrectly detect people
in the room, even when there is no one there
When there is a dog or a cat moving around in the room.
When the wind is making curtains or plants move.
When there are heating units, humidiers, or electric appli-
ances such as oscillating electric fans operating.

AIR CONDITIONER Wall Mounted Type
OPERATING MANUAL
General Information on Operation
Automatic defrosting operation
When outdoor temperature is very low with high humidity, frost
may form on the outdoor unit during the Heating operation, and
it could reduce the operating performance of the product.
For frost protection, a microcomputer-controlled automatic
defrost function is equipped in this air conditioner.
If frost forms, the air conditioner will temporarily stop, and
defrost circuit will operate briey (maximum of 15 minutes.)
The Operation indicator on the indoor unit blinks during this
operation.
If frost forms on the outdoor unit after the Heating operation,
the outdoor unit will stop automatically after it operates for a few
minutes. Then the Automatic defrosting operation starts.
Auto-restart function
In event of power interruption such as a blackout, the air
conditioner stops once. But it restarts automatically and
performs previous operation when the power supply is resumed.
If any power interruption occurs after the timer is set, counting
down of the timer will be reset.
After the power supply is resumed, the Timer indicator on the
indoor unit blinks to notify you that there has been a timer fault.
In such a case, reset the timer for your opportune time.
Heating performance
This air conditioner operates on the heat-pump principle,
absorbing heat from air outdoors and transferring that heat
to the indoor unit. As a result, the operating performance is
reduced as outdoor air temperature drops. If you feel that the
heating performance is insufcient, we recommend you to use
this air conditioner in conjunction with other kinds of heating
appliance.
Group Control (optional)
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same
settings.
Malfunctions caused by other electrical devices:
Use of other electrical appliances such as an electric shaver or
nearby use of a wireless radio transmitter may cause the malfunction
of the air conditioner.
If you encounter such a malfunction, turn off the circuit breaker once.
Then turn it on again, and resume operation by using the remote
controller.
Wired remote controller (option)
The optional wired remote controller can be used.
When you use remote controller, there are following different points
as compared with using wireless remote controller.
[The additional functions for wired remote controller]
• Temperature set back timer
You can use both wired and wireless remote controller
simultaneously. (But function is limited.)
When the restricted functions on the remote controller are used, a
beeping sound will be heard, and the Operation, Timer, and Economy
indicators of the indoor unit will blink.
[The restricted functions for wireless remote controller]
<Wired remote controller (Non-polar 2-wired)>
• Outdoor unit low noise
• 10°C Heat
• Weekly timer
• Powerful
Wireless LAN control (option)
The optional wireless LAN control can be used.

• Water leaks from the unit
Following symptoms do not indicate product malfunction, but they are normal functions or characteristics of this product.
Symptom Cause See page
Operation is delayed after
restart.
To prevent blowout of the fuse, the compressor will not operate while the protection circuit is working
for about 3 minutes after sudden Off→On operation of the power supply. –
Noise is heard. • During operation or immediately after stopping the air conditioner, refrigerant owing sound may be
heard. Also it may be particularly noticeable for 2–3 minutes after starting operation.
• During the operation, a slight squeaking sound produced by the minute expansion and contraction
of the front panel caused by temperature change may be heard.

the Automatic defrosting operation may be seen. 9
Airow is weak or stops. • Immediately after the Heating operation is started, the fan speed stays very low temporarily to
warm up the internal parts of the unit.
• In the Heating mode, the outdoor unit stops and the indoor unit operates at very low fan speed if
the room temperature rises above the set temperature.
–
In the Heating mode, the indoor unit temporarily stops for maximum of 15 minutes to perform the
Automatic defrosting operation while the Operation indicator is blinking. 9
