■OPERATION MODES, FUNCTIONS AND FEATURES
COOL
Cools, dehumidifies and filters the room air. Maintains the desired
room temperature.
HEAT
Heats and filters the room air. Maintains the desired room
temperature.
AUTO
Automatically switches from COOLING to HEATING or from
HEATING to COOLING, maintaining the desired temperature
according to the room conditions.
DRY
Dehumidifies and softly cools the room In DRY Mode, the air
conditioner operates at an increased dehumidifying power. This
function is recommended to be used when temperature is rather
low but the humidity is high.
FAN
Recirculates and filters the room air. Maintains constant air
movement.
AUTO FAN
The air conditioner automatically selects the FAN speed in
accordance with the room temperature. At the start, the unit
operates at high fan speed. As the room air approaches to the
desired temperature, the fan switches to a lower speed for quieter
operation.
HOT KEEP
In HEATING and in AUTO FAN, the fan will be turned off when the compressor is not in operation and
will not be restarted, unless the indoor coil reaches adequate temperature. This HOT KEEP feature
prevents uncomfortable cold air drafts. Use of AUTO FAN is, therefore, recommended when the air
conditioner is in HEATING mode.

TIMER
Real time control and display,automatically turns the air conditioner
ON and OFF according to the time of day setting,ensuring comfort
conditions before returning home, without wasting electricity. It
turns the air conditioner off automatically when sleeping.
SLEEP
Designed to create comfortable sleeping conditions. When in
COOLING mode, the temperature rises one degree centigrade
every hour, for three hours, from the start of the mode. The
temperature rise prevents the feeling of over-cooling while sleeping
(when your body is at rest). In HEATING mode the reverse occurs;
the air conditioner lowers its temperature one degree every hour.
When in SLEEP mode, the air conditioner will be automatically
turned off after seven hours.The result is a more comfortable and
invigorating sleep, which leaves you feeling fresh and energetic in
the morning.
AUTO LOUVER
The air louver is automatically positioned for the most suitable blow-out angle, when COOL, HEAT,
DRY or FAN modes are selected.When the air conditioner is turned off, the louver will close automatically
providing an aesthetic appearance.
VERTICAL AIR SWING
Automatic swing of supply air in vertical direction.The louver moves
automatically in upward and downward direction spread the
conditioned air evenly throughout the room.
ROOMTEMPERATURE
Measures and displays room temperature.
FILTER INDICATION
Filter indicator on the indoor unit display is turned on when the
filter requires cleaning. After cleaning and reinstalling the filter,
the system should be reset.

the unit restarts after a power distruption or failure, it will resume operating in the same mode as
before the power was disrupted.
LOCK
Freezes the last operation setting on the remote control.When LOCK is activated, the remote control
will not be able to control the air-conditioner.
SETTING STORED
The air conditioner will store all the settings of the MODE button in COOL, HEAT, AUTO, DRY and
FAN.
