Features & Benefits
Environment Friendly Refrigerant :
- LG Ceiling Cassette Air Conditioners uses environ­ment friendly refrigerant, which don't do any harm to the environment.
Plasma Air Purifier :
- It removes not only microscopic contaminants & dust, but also house mites, pollen, and pet fur to help preventing allergic diseases like asthma.It provides odor free, dust free and allergy free air.
Group Control :
- It enables to control as much as 16 units with the help of one wired remote controller. All the units will follow same setting of temperature & other sub func­tions.
Central Control :
- It enables to control 16 x 8 = 128 units with the help of 8 controllers. All units can be put on and off from one Central Room. For Setting Temperature, Fan Speed and other sub functions, access the respec­tive LCD wired remote controller of each unit.
Jet Cool :
-In this mode, quick and fast cooling is done. Cold and
high velocity air is supplied to the room till the indoor temperature reaches 18°C. The unit will continue to run in jet cool mode till the Indoor temperature reach­es 18°C.

- It is the function for comfort cooling/heating operation.
- The diagonal two louvers are opened the more larger than the other louvers. After one minute, it is opposite.
Space Control
Vanes angle can be controlled by pair, considering its installation environment.
- For example direct drafts can be annoying, leading to discomfort and reduced productivity vane control helps to eliminate this problem.
- Easily controlled by wired remote control.
- Air Flow can be controlled easily regarding any space environment.
Features & Benefits
Auto Restart Operation :
- Whenever there is electricity failure to the unit, and after resumption of the power, unit will start in the same mode prior to the power failure. Memorized condition are on / off condition, operating mode (cooling/heating), set temperature and fan speed.The unit will memorize the above conditions and start with same memorized condition.
Two Thermistor Control :
- There may be a significant difference between the temperature taken at the installed product and indoor tem­perature. Two thermistor control provides option to control temperature by referring any of the two tempera­tures. With the help of the slide switch at the back of the LCD wired remote controller, selection of the desired thermistor for controlling the unit can be done. One thermistor is in the Indoor unit & the other one is in the LCD wired remote.

High Ceiling Operation
- According to the height of ceiling installation, it pro­vides variability of indoor fan motor rpm. If the height of installation is low then you can adjust low rpm of indoor fan motor. On the other hand if the height of the installation is high you can adjust high rpm of indoor fan motor. Selection of speed can be done by slide switch at the back of the LCD wired remote.
ex:
Selection Height RPM
Lower 2.4m 700/600/500
Standard 2.7m 750/650/550
Higher 3.0m 800/700/600
Water Drain Pump :
- In some of the places natural drainage is not possi­ble. For such places drain pump is very useful. It removes condensed water from the unit.
Time Delay Safety Function :
- It delays restarting of the compressor by three min­utes thereby preventing damage to the compressor.
Zero Standby Power:
- Due to SMPS (Switching Modulation Power Supply) technology, there is almost zero power consumption in the standby mode.
Child Lock Function:
-It prevents the children or others from tampering the
control buttons. Unit can be controlled by the wireless remote controller. This can be easily set by pressing timer key & Min key simultaneously. After child lock is set, pressing any key will displaye CL on the LCD for 3 seconds and all the keys will be ineffective.
