The louver position moves slightlyeach time the button is pressed.● Press “SWING” to engage continuous louver motion.Note: Please refer to the REMOTE CONTROLLER MANUAL for details2.5 Special FunctionsLouver positionMaximum downIn COOLING or DRY mode, condensate mayform and drip from unit in high humidity condition.Narrow openingRestricted air flow reduces performance andmay cause condensate.ClosedDo not operate if it will not open – damagemay occur.Louver actionAfter a quick restart, louver may remainstatic for about 10s.CAUTION■ Louver MemoryHorizontal louver angle is memorised andwill return to the position last selected bythe user.This will not happen in TURBO mode,running by manual control buttons, or aftera power interruption.■ Auto swing of horizontal air flowPress “SWING” for two secends toengage vertical blades swing motion.Note: Please refer to the REMOTECONTROLLER MANUAL for details.Features (Model dependent)■Compressor DelayAt start-up, a time delay of 3 ~ 4 minutesprotects the compressor.■Air Purification*Ionizer*Negative ions are added to the air tosimulate the effects of forests andwaterfalls on humans.Plasma*Dust particles in the passing air stream arecharged electrically. This enhances dustcollection, odour reduction and reducesairborne bacteria mortality.■Mildew Prevention*This function keeps the indoor fan runningin low speed for 7 ~ 10 minutes after beingturned off by the user in cooling mode.Drying the water droplets on the indoorheat exchanger prevents mildew growth.Interrupting this process may scramble the control logic.To reverse this, briefly disconnect the electrical supply. [*] Model dependent.■WIFI Control*With WIFI function, the unit can becontrolled either by remote controller or byyour mobile phone. Connect the WIFImodule and communication module withdisplay board to activate this function.■TurboThe Turbo function makes the unit workextra hard to reach your presenttemperature in the shortest time possible.■ Self Cleaning*Airborne bacteria always grows provided thatthere is moisture on the indoor heat excharger.Regular drying of the exchanger prevents thisgrowth. By simply pressing the “self clean”button, the controller will automatically managethe process.■Cold Draft PreventionTo avoid uncomfortable when the airconditioner get into heating mode, the indoorunit will preheat before the fan starts. Thisdelay should only last a few minutes.■Auto RestartThe unit will automatically restart after apower interruption.Previous user’s settings are all recovered.■Auto DefrostIce develops on the outdoor unit in heatingmode. To defrost this ice, the indoor fanstops for a few minutes before heatingcontinues.■Auto Leak DetectionWhen refrigerant leakage is detected,the unit will display “EC” code or flashLEDs [model dependent].
