FEATURES AND FUNCTIONS
Energy saving and Comfortable function
■
SLEEP TIMER
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.
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.
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.
SWING OPERATION
The Airfl ow Direction Louvers swings automatically up and down
so that the air speeds to every nook and corner of your room.
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.
■
REMOVABLE INTAKE GRILLE
The indoor unit’s intake grille 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.
■
WIRELESS REMOTE CONTROLLER
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.
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.
