Features and Functions

DUAL FAN COMFORT

The 2 types of airﬂ ow (cold/warm air from the main fan, and ambient temperature air from the dual fan) provide comfort throughout the room. This is recommended for those who do not like ordinary COOL/HEAT modes.

• In COOL mode

Cold airﬂ ow

Delivers airﬂ ow with a comfortable temperature.

• In HEAT mode

Side airﬂ ow reduces warm air from rising up, warming from the ﬂ oor level.

Warm air

FILTER CLEAN

Time consuming air ﬁ lter cleaning is done automatically. Dust attached to the air ﬁ lter is removed, preventing a drop in performance.

PLASMA AIR CLEAN

Fine particles such as pollen and house dust are collected with static electricity to make the air in the room clean.

10°C HEAT OPERATIO N

The room temperature can be maintained at 10°C so as to prevent the room temperature from falling too far.

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 operation mode is able to save more energy than other normal modes.

AUTO CHANGEOVER

The operation mode (Cooling, Heating) is switched automatically to maintain the set temperature, and the temperature is kept constant at all times.

FAN CONTROL FOR ENERGY SAVING

When the set temperature is reached during cooling operation, the fan operates intermittently and power is saved.

FINE TEMPERATURE ADJUSTMENTS

The temperature can be set in 0.5°C increments.

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.

General Information on Operation

Automatic defrosting operation

When outdoor temperature is very low with high humidity, frost may form on the outdoor unit during the heating operation, and it could reduce the operating performance of the product. For frost protection, a microcomputer-controlled automatic defrost function is equipped in this air conditioner. If frost forms, the air conditioner will temporarily stop, and defrost circuit will operate brieﬂ y (maximum of 15 minutes.) "OPERATION" indicator on the indoor unit blinks during this operation. If frost forms on the outdoor unit after the heating operation, the outdoor unit will stop automatically after it operates for a few minutes. Then the automatic defrosting operation starts.

Auto-restart function

In event of power interruption such as a blackout, the air conditioner stops once. But it restarts automatically and performs previous operation when the power supply is resumed.

If any power interruption occurs after the timer is set, counting down of the timer will be reset. After the power supply is resumed, the "TIMER" indicator on the indoor unit blinks to notify you that there has been a timer fault. In such a case, reset the timer for your opportune time.

Heating performance

This air conditioner operates on the heat-pump principle, absorbing heat from air outdoors and transferring that heat to the indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that the heating performance is insufﬁ cient, we recommend you to use this air conditioner in conjunction with other kinds of heating appliance.

Malfunctions caused by other electrical devices:

Use of other electrical appliances such as an electric shaver or nearby use of a wireless radio transmitter may cause the malfunction of the air conditioner. If you encounter such a malfunction, turn off the circuit breaker once. Then turn it on again, and resume operation by using the remote controller.

Wireless LAN control

You can operate the air conditioner indoor unit with a smartphone or tablet by connecting it with a WLAN adapter. For detailed instructions, please refer to the setting manual.
