7 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 (cooling/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 thermistor 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 accurately.(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 Single Package (50Hz, Above 5 Ton)

8 3. Features & Benefits Child Lock Function : - It prevents the children or others from tampering with 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, by pressing any key CL will be displayed on the LCD for 3 seconds and all the keys are ineffective. Defrost / Deicing : CHILD LOCK -Display - 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 controller & diagnosis can be done as per the code indication.the same is also printed on key cover of the LCD wired 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 from one Central Room.For Setting Temperature, Fan Speed and other sub functions, access the LCD wired remote controller of each unit.
