Real time control and display, automatically turns the air conditioner ON and

automatically when sleeping.
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.
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.
Switches the temperature sensing point to the place where the remote
control is located. (For general air conditioner, the temperature sensor is only
located behind the air intake grille). This function is designed to provide a
personalized environment by transmitting the temperature control command
from the location next to you. The communication between the Remote
Control and the unit is done by infra-red signal. Therefore, in using this
function, the Remote Control should always be aimed , without obstructions,
at the air conditioner.
Designed to create comfortable sleeping conditions. When in COOLING
mode, the temperature rises one degree centigrade after each consecutive
hour, up to 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, up to three hours, from the start of the mode. When in
SLEEP mode, the air conditioner will be automatically turned off after having
operated for eight hours. The result is a more comfortable and invigorating
sleep, which leaves you feeling fresh and energetic on the next morning.
Automatically choose COOLING or HEATING or DRY,
maintaining the desired temperature according to the room conditions.
