8. Electronic function

8.1 Abbreviation

T1: Indoor room temperature

T2: Coil temperature of evaporator

T3: Coil temperature of condenser

T4: Outdoor ambient temperature

T5: Compressor discharge temperature

8.2 Display function

8.2.1 Icon explanation on indoor display board.

Auto indicator

This indicator illuminates when the air conditioner is in AUTO operation.

Timer indic

ator

This indicator illuminates when TIMER is set ON/OFF.

PRE.

-DEF. Indicator(only for heat pump models)

This indicator illuminates when the air conditioner starts defrosting automatically or when the warm air

control feature is activated in heating mode.

TEMPERATURE indicator

Usually it displays the temperature settings. When change the setting temperature, this indicator

begins to flash, and stops 20 seconds later. It displays the room temperature when the air conditioner

is in FAN only operation, and the range of that is 0~50 . When the unit stops operation, it returns to

original factory settings. It will also display the codes when malfunction or protection happen.
