- When no human motions are detected for about 20 minutes, Energy-saving mode starts and the set temperature can change to up to 28^ .

- When human motions are detected in Energy-saving mode, the previous operation restarts.

NOTE

• The motion detect function operates only in Cool mode.
• The motion detect sensor can detect human motions within 5 m. It may not detect human motions outside the range.
• If any obstacle exists in front of the sensor or the site is subject to direct sunlight or wind, the sensor may not operate properly.
• The motion detect sensor can more easily detect the side to side motions of a person than the back and forth motions.
• The motion detect sensor is located at the bottom right of the product. Therefore, when a person is located around the center of the product, the sensor recognizes that the person is located at the left and the product blows air accordingly.
• Some areas around the center of the sensor may not be detected.
• The motions of a warm-blooded pet, swinging heater, or robot cleaner can be recognized as human motions.
• When a person stops movement within the detectable range, it may not be detected.
• Because the motion detect sensor can recognize movement of heats, it may not operate when a person turns backwards, exposes the skin less or is blocked by obstacles such as laundry.
• The sensor's sensitivity may be lowered depending on the thickness of clothes.
• If you change the current mode, airflow direction, or optional function, the motion detect function is canceled.
• If a person takes body motions in the same place or there is no movement for a long time, it is recognized as an absence.
• If there are little motions such as in cases of infants and patients, or if little motions continue such as in cases of sleeping and movie watching, it can be recognized as an absence.
• Do not place a large object, heating appliance, or humidifier near the product.
• Do not touch the sensor. Failing to do so may result in product damage or malfunction.

Troubleshooting

If the air conditioner is not operating normally, refer to the troubleshooting guide below.

Problem Solution
The air conditioner stops working.	Make sure the unit is receiving power.Check the circuit breaker. If it is flipped off, flip it on again and restart the unit. If the problem persists, contact your service provider.The Timed off function may have turned off the unit. Turn on the unit again.
Cannot change the temperature.	Check if the unit is in Fan or Fast mode. If so, you cannot change the set temperature; the unit automatically controls the set temperature.
Improper airflow temperature.	Check the set temperature. In Cool mode, cooling occurs only when the set temperature is lower than the current temperature.Use the (Temperature) button on the remote control to change the set temperature.Check if the air filter is blocked with dirt or debris. If the air filter is blocked, the cooling performance may decrease. Clean the air filter regularly (page 34).Check if the outdoor unit is covered or is installed near obstacles. Remove the coverings and obstacles.Check if doors or windows are open. This may cause poor circulation or performance. Close all doors and windows.Check if the pipe length between the units exceeds the maximum pipe length (see “Typical installation” in the Installation manual). If so, the cooling performance may decrease.
Cannot change the airflow direction.	Check if the good'sleep function is on in Cool mode. If so, you cannot control the airflow direction.
Cannot change the fan speed.	Check if the unit is in Auto, Dry, or Fast mode or the good'sleep function is on in Cool mode. In these conditions, you cannot control the fan speed; the unit automatically controls the fan speed.
The remote control does not work.	Replace the batteries in the remote control.Make sure the remote control can send an unobstructed signal to the unit.Keep bright lights away from the unit. Light from fluorescent bulbs or neon signs may interrupt the signal from the remote control.
The Timed on/off function does not work.	Make sure to press the SET (SET) button on the remote control when setting the timer.
The indicator on the remote control blinks continuously.	Press the (Power) button to turn off the unit, or disconnect the power plug.If the indicator light on the remote control continues blinking, contact your service provider.
Odors are coming from the unit during regular operation.	If the unit is operating in a smoky area, ventilate the room or operate the unit in Fan mode for 3 to 4 hours. There are no components in the unit that produce a strong odor.Check if the drain lines are clean. Clean them regularly.
The remote control display shows an error message.	If the indoor unit indicator blinks, write down the error code. Contact your service provider and provide them with the error code.
The unit is generating noise.	It is normal for the unit to generate some noise while operating. If the pipe length between the units is less than 3 m and no coil was used (see “Typical installation” in the Installation manual), additional noise may be transmitted from the outdoor unit to the indoor unit via the piping.
Water drips from the pipe connections on the outdoor unit.	Condensation may develop when the ambient temperature or humidity changes significantly. This is normal.
