SYSTEM DESCRIPTION

OPERATION MODES, FUNCTIONS AND FEATURES

Cools, dehumidifies and filters the room air. Maintains desired room

temperature.

Heats and filters the room air. Maintains the desired room temperature.

Automatically switches from COOLING to HEATING or from HEATING to

COOLING, maintaining the desired temperature according to the room

conditions.

Decreases humidity of atmosphere and maintains the room temperature. It

is suitable to use in dankish and rainy season.

Recirculates and filters the room air. Maintains constant air movement in the

room.

The air conditioner automatically selects the fan speed according to the

room temperature. At the start, the unit operates at high fan speed. As the

room air approaches to the set temperature, the fan switches automatically

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.

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.

This series of conditioners have the following functions:

HOT KEEP

SLEEP

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 rising temperature

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 sleeping mode, air conditioner

will be automatically turned off after operating for seven hours. The result is

a more comfortable and invigorating sleep, which leaves you feeling fresh

and energetic on the next morning.
