2-3-1. Compressor is off and is in 3 mins standby.
Fan will stop if compressor stops
Fan is at super low level upon the end of 3 mins standby.
Compressor is on after 3 mins standby.
2-3-2. Compressor is on.
When airflow is set at high, mid or low level, fan will operate as per the setting.
When in automatic airflow mode, airflow is determined as per temperature.
Three. Air Refreshing
Up reception of remote control signal, negative ion generator will start operation to emit negative ion if
fan is operating.
If fan stops, negative ion generator is off.
When negative ion generator is off, if air-refreshing feature is set and fan restarts then negative ion
generator is on.
Four. Timed Operation
Time counting will start based on the difference of timer clock and current clock.
In timed operation, display panel timer lamp is on.
4-1. Timer Off
When timer off is set, panel timer lamp is on and unit will stop operation as per the timing.
4-2. Timer On
If timer on is set, when unit is off, panel timer lamp will be on and unit will resume operation as per the
timing and in set mode.
Execution sequence is based on the setting.
Five. Sleep Operation
When remote control set sleep mode, timer lamp is on.
5£ - 1 . In cooling/dehumidification mode, set temperature will rise 1
o
1 C after the second hour. The unit will stop after another 6 hours.
5£-2. In heating mode, set temperature will fall 2
o
and will rise 1 C after another 3 hours and the unit will stop after another 3 hours.
5£-3 If airflow of indoor fan is high before setting sleep mode, then it will turn into mid level after sleep
mode is set. If airflow of indoor fan is mid before setting, it will turn into low level after setting. If airflow of
indoor fan is low before setting, then it will not change after setting.
Six. Automatic Operation
Automatic operation consists of two features of automatic and full automatic, which can be realized
through EEPROM selection.
6-1. Automatic Operation Mode:
On entering this mode, main control unit will decide the corresponding operation mode as per room
temperature to maintain the set temperature£ ¨ Set temperature is 23¡ æ in heating mode and 26¡ æ
cooling mode.£ © .
Upon initial startup, the unit will enter heating mode if room inlet air temperature is equal to or lower
than 23¡ æ or it will enter cooling mode if temperature is higher than 23¡ æ .
When entering heating mode, the unit will operate as per heating program£ ¨ set temperature is 23¡ æ £ ©
Upon reaching temperature where compressor stops operation, compressor will stop and standby for 3
mins. In case it detects that inlet air temperature is higher than 27
unit will enter cooling mode. Otherwise, the unit will remain in heating mode.
When entering cooling mode, the unit will operate as per cooling program £ ¨ set temperature is 26¡ æ £ © .
Temperature difference compensation is automatically cancelled. Upon reaching temperature where
compressor stops operation, compressor will stop and standby for 3 mins. In case it detects that inlet air
temperature is equal to or lower than 23¡ æ
mode. Otherwise, the unit will remain in cooling mode.
