3. Features & Benefits

Cooling, Heating & Fan Operation :- LG air conditioners can provide cooling, heating & fan operation. In the cooling mode, it cools the air with an

operation range of 18~30°C. In the heating mode, it heats the air with an operation range of 16~30°C. In the

fan operation mode, only indoor fan at the selected speed will run, outdoor fan and compressor will be off.

Auto Restart Operation :- Whenever there is electricity failure the system shuts off and resumption of the power, unit will start in the

same mode as prior to the power failure. Memorized condition are on / off condition, operating mode (cool-

ing/heating), set temperature and fan speed.

LCD Wired Remote Control :- It can control all the functions of the unit. You can

check/set temperature, change operation mode,

set timer & also diagnose the error of the unit. It

also has the weekly program.

Two Thermistor Control(Return Air Control):(Accessory)-There may be a significant difference between the return air temperature in the duct and the room temperature.

Return air sensing tempeaturee is designed to control temperature more accurately by applying additional ther-

mistor which senses the return air temperature inside the duct specially.

After selecting the duct thermistor, which is connected to the main PCB, the room temperature measurement

by LCD wired remote control thermistor is neglected. It helps to control the room temperature more accurate-

ly.(Thermistor is a field-installed accessory)

Group Control :- It enables to control max of 16 units with the help of

one wired remote controller. All the units will follow

same setting of temperature & other sub functions.

CHILD LOCK-Display

Child Lock Function :- It prevents the children or others from tampering

with the control buttons. Unit can be controlled bythe wireless remote controller.This can be easily setby pressing timer key & Min keysimultaneously.After child lock is set, by pressingany key CL will be displayed on the LCD for 3 sec-onds and all the keys are ineffective.

Defrost / Deicing :- In the heating mode, it prevents the ice formation on the outdoor unit. The heating cycle is reversed to the

cooling cycle to defrost the evaporator pipe of the outdoor unit. While defrost cycle, the compressor is on and

indoor fan, outdoor fan and 4-way valve are off.

Hot Start Function :- During starting of the unit in the heating mode it prevents cold air blow from the unit.It starts the indoor fan

only after indoor unit pipe temperature reaches a preset value.

Time Delay Relay :- It delays restarting of the compressor by three minutes thereby preventing damage to the compressor .

Self Diagnosis Function :- This function provides diagnosis of the unit. An error code will be displayed on the LCD wired remote con-

troller & diagnosis can be done as per the code indication.The same is also printed on key cover of the LCDwired remote controller.

Central Control :(Accessory)- It enables to control 16 x 8 = 128 units with the help

of 8 controllers. All units can be put on and off fromone Central Room.For Setting Temperature, FanSpeed and other sub functions, access the LCDwired remote controller of each unit.

Zone Control :(Accessory)- It controls the temperature of each zone. Opening or closing of

the damper is controlled by sensing the temperature of eachzone.In the cooling mode, if the temperature of a particular zoneis lower than set temperature then the damper is closed. On theother hand, if the temperature of a particular zone is higher thanthe set temperature damper is open to provide cooling to thezone and vice versa in the heating mode.

Electronic Thermostat:(Accessory)- It provides on/off timer up to 24 hours. Also self-diagnose the

problem.

Weekly Program :- It provides on / off schedule of operation for a period of one

week.

Wireless Remote Control:(Accessory)- It provides ease of control.

Electric Heater:(Accessory)- Electric Heater can be used to provide heat in addition to cycle

heat. It also provides quick heating. It can also work as a standalone heater with only fan operation.

Fire Alarm Function:- By purchasing a fire alarm locally, installation of the fire alarm is

possible.In case of any fire, alarm will sound and the unit will becompletely stopped.

Energy Saving Gold Fin:(Optional)- Outdoor Heat Exchanger fins are coated with anticorrosive &

hydrophilic layers. It prevents the corrosion of heat exchanger.Fins remains as new even after long time and maintains efficien-cy of heat exchanger. Saves power & maintenance Cost.

Soft Start Function:- All single package air conditioners has soft start function i.e.

Indoor fan, outdoor fan & compressor start in sequence to pre-vent overcurrent during starting.
