Provide maximum comfort, clean air and optimise energy saving
ECONAVI and AUTO COMFORT The Right Choice for Energy Saving
Equipped with the human activity sensor, the air conditioner ensures to deliver cool or warm air to you, and keeps the room consistently comfortable with minimum energy consumption.
Furthermore, the sunlight sensor detects the sunlight intensity and helps control heating/cooling temperatures to provide optimum comfort.
nanoe-G Purifies the air down to the smallest particles
Deactivates harmful micro-organisms such as viruses, bacteria, etc. to keep air clean. It also deactivates viruses and bacteria on the filter to keep inside of the unit clean.
See "To learn more..." for details.

Multi air conditioner system
Multi air conditioner systems save space by letting you connect multiple indoor units to a single outdoor unit.
- For complete product features, please refer catalogue.
Indoor units
- It is possible to operate the indoor units individually or simultaneously. The priority of operation is placed on the first unit that turned on.
- During operation, HEAT and COOL modes cannot activate at the same time for different indoor units.
- The power indicator blinks to indicate the indoor unit is standing by for a different operation mode.
- For system which HEAT mode has been locked, if operation mode other than HEAT is selected, the indoor unit stops and the POWER indicator blinks.

Human activity sensor operation
ECONAVI; Detecting human presence and activity, the unit controls room temperature to save energy.

AUTO COMFORT; Detecting human presence and activity, the unit controls room temperature to keep human comfortable consistently.

ECONAVI and AUTO COMFORT
Precise control of temperature during low activity to maximise energy saving.

ECONAVI and AUTO COMFORT take advantage of the human nature that human being takes time to feel the temperature rise during low activity level; the unit adjusts temperature to maximise energy saving without sacrificing the comfort.
- During low activity, fan speed 1 tap up for first 15 minutes or until set temperature is reached.
** During human absence, maximum fan speed for COOL/DRY mode is medium fan.
The human activity sensor will also scan for area of heat source and movement in a room.
Detection area
- Based on area activeness horizontal airflow direction louver will adjust either fix at predetermined position or swing left/right periodically.

-
The human activity sensor performance is influenced by indoor unit location, movement speed, temperature range, etc.
The human activity sensor may:
-
mistakenly detect an object with heat source & movement similar to human, such as pets, etc.
-
mistakenly detect as non-heat source & movement if a human stays motionless for certain period of time.
-
Do not place large objects near the sensor and keep away heating units or humidifier from the sensor's detection area. They may cause sensor malfunction.
Sunlight Sensor operation
ECONAVI; Detecting sunlight intensity, the unit adjust temperature to save energy.

ECONAVI is activated, the unit maintains set temperature until a high sunlight intensity is detected. The sunlight sensor detects sunlight intensity during weather or day/night changes, and the unit adjusts temperature.
- In a room without window or with thick curtain, the sunlight sensor will judge as cloudy/night.

For seasonal inspection after extended non-use
- Checking of remote control batteries.
- No obstruction at air inlet and air outlet vents.
- Use Auto OFF/ON button to select COOL/HEAT operation. After 15 minutes of operation, it is normal to have the following temperature difference between air inlet and air outlet vents:
COOL: ≥8°C HEAT: ≥14°C
For extended non-use
- Activate HEAT mode for 2~3 hours to remove moisture left in the internal parts thoroughly to prevent mould growth.
- Turn off the power supply and unplug.
- Remove the remote control batteries.
The following symptoms do not indicate malfunction.
| Symptom | Cause |
| Mist emerges from indoor unit. | •Condensation effect due to cooling process. |
| Water flowing sound during operation. | •Refrigerant flow inside the unit. |
| The room has a peculiar odour. | •This may be due to damp smell emitted by the wall, carpet, furniture or clothing. |
| Indoor fan stops occasionally during automatic fan speed setting. | •This helps to remove the surrounding odour. |
| Airflow continues even after operation has stopped. | •Extraction of remaining heat from the indoor unit (maximum 30 seconds). |
| Operation is delayed a few minutes after restarting. | •The delay is a protection to the unit's compressor. |
| Outdoor unit emits water/steam. | •Condensation or evaporation occurs on pipes. |
| TIMER indicator is always on. | •The timer setting repeats daily once set. |
| POWER indicator blinks during HEAT mode with no warm air supply (and louver is closed). | •The unit is in defrost mode (and AIR SWING is set to AUTO). |
| Indoor fan stops occasionally during heating operation. | •To avoid unintended cooling effect. |
| POWER indicator blinks before the unit is switched on. | •This is a preliminary step in preparation for the operation when the ON timer has been set. |
| Cracking sound during operation. | •Changes of temperature caused the expansion/contraction of the unit. |
| Discoloration of some plastic parts. | •Discoloration is subject to material types used in plastic parts, accelerated when exposed to heat, sun light, UV light, or environmental factor. |
| Dust may have collected around the front panel, grilles and wall surrounding the unit after extended use. | •The dust accumulation is due to air purification effect of negative ions from nanoe-G. Remove the dust regularly with a clean dampened cloth. |
Check the following before calling for servicing.
| Symptom | Check |
| Operation in HEAT/COOL mode is not working efficiently. | ·Set the temperature correctly.
·Close all doors and windows.
·Clean or replace the filters.
·Clear any obstruction at the air inlet and air outlet vents. |
| Noisy during operation. | ·Check if the unit has been installed at an incline.
·Close the front panel properly. |
| Remote control does not work.
(Display is dim or transmission signal is weak.) | ·Insert the batteries correctly.
·Replace weak batteries. |
| The unit does not work. | ·Check if the circuit breaker is tripped.
