03.03. Features

NOTE

Refer to remote manual for full features list.

Auto-Restart

If the unit loses power, it will automatically restart with the prior settings once power has been restored.

Anti-mildew

When the unit is turned oﬀ after COOL, AUTO or DRY mode, the unit will continue to operate a low power to dry up

condensed water to prevent mildew growth.

Easyconnect Control (Optional)

Allows you to control the unit using a mobile phone and a wireless connection. Installation is required to be undertaken

by a licensed technician. Easyconnect is an accessory that may be purchased separately.

Louvre Angel Memory

When turning on your unit, the louvre will automatically resume its former angle. Aim the louvre higher to avoid direct

airﬂow. This setting is found under the SET menu.

Active Clean Function

It washes away dust, mold and grease when it adheres to the heat exchanger, by automatically freezing and then rapidly

thawing frost. Active Clean function is used to produce more condensed water to improve the cleaning eﬀect. After

cleaning, the internal blower fan operates with hot air to blow-dry the evaporator and prevent the growth of mold.

When this function is turned on, the indoor unit will display CL. After 20 to 45 minutes, the unit will turn oﬀ

automatically and Active Clean function will be deactivated.
