FEATURES AND FUNCTIONS
O
Energy saving and Comfortable function
INVERTER
At the start of operation, large amount of 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.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode and
lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy than other normal mode.
OMNI-DIRECTIONAL AIR FLOW
(SWING OPERATION)
3-dimensional control over air direction swing is possible through
dual use of both an up/down air direction swing and right/left air
direction swing. Since up/down air direction flaps operate automatically according to the operating mode of the unit, it is possible to set air direction based on the operating mode.
SUPER QUIET OPERATION
When the FAN button is used to select QUIET, the indoor unit
begins super quiet operation; the indoor unit’s airflow is reduced to produce quieter operation.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature
is kept constant at all times.
10 °C HEAT OPERATION
The room temperature can be maintained at 10°C so as to
prevent the room temperature from falling too far.
O
Convenient function
PROGRAM TIMER
The program timer allows you to integrate OFF timer and ON
timer operations in a single sequence. The sequence can involve 1 transition from OFF timer to ON timer, or from ON
timer to OFF timer, within a 24 hour period.
SLEEP TIMER
When the SLEEP timer button is pressed 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.
O
Clean function
REMOVABLE AIR FILTER
The indoor unit’s air filter can be removed for easy cleaning
and maintenance.
MILDEW-RESISTANT FILTER
The air filter has been treated to resist mildew growth, thus
allowing cleaner use and easier care.
O
Remote controller
WIRELESS REMOTE CONTROLLER
The wireless remote controller allows convenient control of air
conditioner operation.
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 ones]
