Specific Functions

• Breeze Away Function: This feature avoids direct air flow from blowing on the room's occupants. Available under COOL, FAN and DRY mode only.
• Active Clean Function: The Active Clean Technology washes away dust, mold, and grease that may cause odors by automatically freezing and then rapidly thawing the frost. When this function is turned on, the indoor unit window displays "CL", after 20 to 45 minutes, the unit turns off automatically and cancels the CLEAN function.
• FRESH Function: When the FRESH function is initiated, the Ionizer/Plasma Dust Collector (depending on models) is energized and helps to remove pollen and impurities from the air.
• SLEEP Function: The SLEEP function is used to decrease energy use while you sleep. This function can only be activated via remote controller. Not available in FAN or DRY mode.
• FOLLOW ME Function: The FOLLOW ME function enables the remote control to measure the temperature at its current location and sends this signal to the air conditioner every 3 minutes. When using the AUTO, COOL or HEAT modes, measuring the ambient temperature from the remote controller (instead from the indoor unit itself) allows the air conditioner to optimize the temperature around the occupants to ensure maximum comfort.
• AP Function: Select the AP function to configure the wireless network. For some units, it does not work by pressing SET. To enter the AP mode, continuously press LED seven times for 10 seconds.

FREEZE Protection

With the unit in HEAT mode and the wireless remote pointed at the indoor unit, press the down arrow until the setpoint is 60°F (16°C). Press the down arrow two times within two seconds to activate the 46°F (8°C) heating function (heating set back). The unit will now operate at a set temperature of 46°F (8°C). The indoor unit display shows FP. No icon appears on the remote control. This function is only available in the heating mode. Under this function, the unit heats at high fan speed until the space temperature is 46°F (8°C). This mode can also be deactivated by pressing ON/OFF, SLEEP, MODE, FAN, or either TEMP arrow.

Features

The unit provides the following features for added comfort and safety.

• Time Delay: If ON/OFF is pressed too soon after a stop, the compressor will not start for 3 to 4 minutes due to the inherent protection against frequent compressor cycling. The unit only emits an audible beep when the signals are received correctly.
• Heating: If the unit is in HEATING mode, there is a delay when the fan starts. The fan starts only after the coil is warmed up to prevent cold blow.
• Auto Defrost Operation: In the HEATING mode, if the outdoor coil is frosted, the indoor fan and outdoor fan turns off while the system removes the frost on the outdoor coil. The system automatically reverts to normal operation when frost is removed from the outdoor unit.
• Auto Start: If the power fails while the unit is operating, the unit stores the operating condition, and it will start operation automatically under those conditions when the power is restored.
• Auto-Restart (some units): If the unit loses power, it automatically restarts with the prior settings once power has been restored.
• Anti-mildew (some units): When turning off the unit from COOL, AUTO (COOL), or DRY modes, the air conditioner continues to operate at very low power to dry up any condensed water and prevent mildew growth.
• Wireless Control (some units): Wireless control allows users to control the air conditioner using a mobile phone and a wireless connection. For the USB device access, replacement, maintenance operations must be carried out by professional staff.
• Louver Angle Memory (some units): When turning on the unit, the louver automatically resumes its former angle.
• Breeze Away (some units): This feature avoids direct air flow from blowing on inhabitants.
• Refrigerant Leak Detection (some units): The indoor unit automatically displays ELOC when it detects refrigerant leakage.
• Occupancy Sensor: The system is controlled intelligently under the Occupancy Sensor mode. The feature detects the movement in the room. In COOLING mode, when occupants are away for 30 minutes, the unit automatically lowers the frequency to save energy (for Inverter models only). And the unit automatically starts and resumes operation when movement is detected. This feature cannot be used in a multi-zone system.

Resetting the Remote Control

If the batteries in the remote control are removed, the current settings cancel and the control returns to the initial settings and enters the STANDBY mode. Push ON/OFF to activate.

NOTE: For multi-zone air conditioners, the following functions are not available: ACTIVE CLEAN, SILENCE, BREEZE AWAY, REFRIGERANT LEAKAGE DETECTION and ECO.

Setting Vertical Angle of Air Flow

While the unit is on, press SWING on the remote control to initiate the horizontal louver AUTO SWING feature.

NOTE: When using the COOL or DRY mode, do not set the louver at too high of an angle for long periods of time. Doing so can cause water to condense on the louver blade, which may drop on your floor or furnishings.

When using the COOL or HEAT mode, setting the louver at too high of an angle can reduce the performance of the unit due to restricted air flow.

Setting Horizontal Angle of Air Flow

When the unit is on, press and hold SWING for 2 seconds on the remote control to initiate the vertical louver auto swing feature to control the horizontal angle of the airflow.

ECO/Gear Function

Used to enter the ENERGY EFFICIENT mode and is only available in the COOLING mode. When in COOLING mode, press ECO/GEAR, the remote controller will maintain the temperature automatically between 75°F and 86°F, and set the fan speed to Auto. Operation time in the ECO mode is 8 hours. After 8 hours, or if a conflicting setting is engaged, the air conditioner exits this mode. Gear operation is engaged by cycling through the ECO/GEAR operations. After ECO, there is a setting for up to 75% and 50% of the unit's electrical consumption. The last step in the cycle is the previous unit setting before ECO setting is engaged again and the cycle starts over.

SILENCE Function

Press FAN for more than 2 seconds to activate/disable the SILENCE function (some units). Due to the compressor's low frequency operation, it may result in insufficient cooling and heating capacity. Press ON/OFF, MODE, SLEEP, TURBO or CLEAN while operating to cancel the SILENCE function.

LOCK Function

Press BOOST and HUMIDITY together at the same time more than 5 seconds to activate the LOCK function.

NOTE: The buttons will not respond unless the user press these two buttons for two seconds again to disable the lock.

BOOST Function

When the user selects BOOST feature in the COOL mode, the unit blows cool air with the strongest wind setting to jump-start the cooling process. When users select BOOST in the HEAT mode (for units with Electric heat elements) the electric heater activates and jump-starts the heating process.

Manual Operation (without remote control)

The manual button is intended for testing purposes and emergency operation only. Please do not use this function unless the remote control is lost and it is absolutely necessary. To restore regular operation, use the remote control to activate the unit. The unit must be turned off before manual operation.

Use the following steps to operate the unit manually:
