FEATURES AND FUNCTIONS
AUTO CHANGEOVER
The operation mode (cooling, heating) is switched automatically to maintain the set temperature, and the temperature
is kept constant at all times.
SLEEP TIMER
When SLEEP is selected be pressing TIMER button during
Heating mode, the air conditioner’s thermostat setting is
gradually lowered during the period of operation; during
Cooling or Dry mode, the thermostat setting is gradually
raised during the period of operation. When the set time is
reached, the unit automatically turns off.
SWING OPERATION
The Air Flow Direction Louvers swings automatically up and
down so that the air speeds to every nook and corner of
your room.
WIRELESS REMOTE CONTROL UNIT
The Wireless Remote Control Unit allows convenient control of air conditioner operation.
INVERTER
At the start of operation, a large power is used to bring the
room quickly to the desired temperature. Afterwards, the
unit automatically switches to a low power setting for economic and comfortable operation.
PROGRAM TIMER
The program timer allows you to integrate OFF timer and
ON timer operations in a single sequence. The sequence
can involve one transition from OFF timer to ON timer, or
from ON timer to OFF timer, within a twenty-four hour period.
MILDEW-RESISTANT FILTER
The AIR FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
SUPER QUIET OPERATION
When the FAN CONTROL button is used to select QUIET,
the unit begins super-quiet operation; the indoor unit’s air-
flow is reduced to produce quieter operation.
AIR CLEANING MODE
Relies on the air conditioner’s power to quickly purify the
air in the room.
ELECTRONIC AIR CLEAN FILTER
Install for use inside of the dust collection unit. For details
on how to install the filter, please refer to page 15.
Electrical power is used to charge the filter to remove contaminants from the air and to effectively collect dust and
remove odors. It also helps to reduce the bacterial activity.
COIL DRY OPERATION
The Indoor unit can be dried by pressing the COIL DRY button on the Remote Control Unit so as to avoid going moldy
and restrain the breed of bacterium.
WIRED REMOTE CONTROL UNIT (OPTION)
The optional wired remote control unit (model No.: AR-3TA ) can be used.
When you use remote control unit, there are following different points as compared with
using wireless remote control unit.
[The additional functions for wired ones]
• Weekly timer
• Temperature set back timer
[The restricted functions for wired ones]
• Air-cleaning function can’t be turned ON/OFF. (During operation, it is always ON)
• QUIET can’t be selected in FAN MODE.
• Sleep-timer can’t be used.
• COIL DRY OPERATION can’t be used.
And you can’t use both wired remote control unit and wireless simultaneously.
(Only one kind can be selected)

Each time the button is pressed, the fan speed changes in the following order:
AUTO HIGH MED LOW QUIET
About three seconds later, the entire display will reappear.
When set to AUTO:
Heating : Fan operates so as to optimally circulate warmed air.
However, the fan will operate at very low speed when the temperature
of the air issued from the indoor unit is low.
Cooling : As the room temperature approaches that of the thermostat setting,
the fan speed becomes slower.
Fan : The fan runs at the low fan speed.
The fan will operate at a very low setting during Monitor operation
and at the start of the Heating mode.
When set to QUIET:
SUPER QUIET operation begins. The indoor unit’s airflow will be reduced for quieter operation.
● SUPER QUIET operation cannot be used during Dry mode. (The same is true
when dry mode is selected during AUTO mode operation.)
