12.7 Powerful Mode Operation
When the powerful mode is selected, the internal setting temperature will shift lower up to 2°C (for Cooling/Soft
Dry) or higher up to 3.5°C (for Heating) than remote control setting temperature for 20 minutes to achieve the
setting temperature quickly.

12.8 Timer Control
There are 2 sets of ON and OFF timer available to turn the unit ON or OFF at different preset time.
If more than one timer had been set, the upcoming timer will be displayed and will activate in sequence.

Timer
Control
ON timer 1 and ON timer 2 can be set using remote control, the unit with timer set will start operate earlier than
the setting time.
This is to provide a comfortable environment when reaching the set ON time.
This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to
determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting
time.

From the above judgment, the decided operation will start operate earlier than the set time as shown below.
12.8.2 OFF Timer Control
OFF timer 1 and OFF timer 2 can be set using remote control, the unit with timer set will stop operate at set time.

12.11 nanoe-G Operation
This operation provides clean air by producing great amount of negative ions and distribute through the
discharge airflow to capture or deactivate molds, bacteria or viruses.
nanoe-G operation start condition
o
During unit running at any operation mode, if nanoe-G operation is activated, combination operation
(operation mode + nanoe-G operation) starts.
o
During unit is OFF, if nanoe-G operation is activated, nanoe-G individual operation starts.
nanoe-G operation stop condition
o
When OFF/ON button is pressed to stop the operation.
o
When nanoe-G button is pressed.
o
When OFF Timer activates.
nanoe-G operation pause condition
o
When indoor fan stop (during deice, odor cut control, thermostat off, etc.). nanoe-G operation resume after
indoor fan restarts.
o
When indoor intake temperature ≥ 40°C. nanoe-G operation resume after indoor intake temperature ≤ 40°C
continuously for 30 minutes.
Indoor
fan
control
o
During any operation mode combines with nanoe-G operation, fan speed follows respective operation mode.
However, nanoe-G system enabled when fan speed ≥ 500rpm to ensure proper negative ion distribution,
nanoe-G system disabled when fan speed < 500 rpm.
nanoe-G system disabled when fan speed < 500 rpm.
o
During nanoe-G individual operation, only Auto Fan Speed and no Powerful operation is allowed. Even if Fan
Speed button is pressed, no signal is sent to the unit and no change on remote control display. Auto Fan
Speed for nanoe-G operation changes from SHi to Hi after 4 hours of operation.
Speed for nanoe-G operation changes from SHi to Hi after 4 hours of operation.
Airflow direction control
o
During any operation mode combines with nanoe-G operation, airflow direction follows respective operation
mode.
o
During nanoe-G individual operation, only Auto Air Swing is allowed. Even if Air Swing button is pressed, no
signal is sent to the unit and no change on remote control display.
