12.5 Quiet Operation
Purpose
o To provide quiet operation compare to normal operation.
Control
condition
o Quiet operation start condition
When “QUIET” button at remote control is pressed.
“
” shown in LCD of remote control.
o Quiet operation stop condition
When one of the following conditions is satisfied, quiet operation stops:
QUIET button is pressed again.
Stop by OFF/ON button.
FAN SPEED button is pressed.
AUTO COMFORT button is pressed.
ECONAVI button is pressed.
When fan speed is changed, fan speed follows the setting change.
When operation mode is changed, resume previous operation setting.
During quiet operation, if timer “on” activates, quiet operation maintains.
12.6 Powerful Mode Operation
When the powerful mode is selected, the internal setting temperature will shift lower up to 1°C (for Cooling) or
higher up to 1.7°C (for Heating) than remote control setting temperature to achieve the setting temperature
quickly.
quickly.
12.7 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.
12.7.1 ON
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.
70 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.
time.
From the above judgment, the decided operation will start operate earlier than the set time as shown below.
12.7.2 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.

12.7.3 Sleep
Timer
Sleep operation is performed according to the delay OFF time (0.5, 1, 2, 3, 5, 7 or 9 hr) and provide comfortable
environment by shifting set temperature.

12.8 Auto Restart Control
When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within
three to four minutes (various period of protection control is programmed) after power supply resumes.
This type of control is not applicable during ON/OFF Timer setting.

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 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 ≥ 490 rpm to ensure proper negative ion distribution,
nanoe-G system disabled when fan speed < 490 rpm.
nanoe-G system disabled when fan speed < 490 rpm.
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, any airflow direction can be combined.
Timer
control
o When ON Timer activates during any operation, no change on current operation.
o When OFF Timer activates during any operation, all operation stops and the latest nanoe-G operation status
o When OFF Timer activates during any operation, all operation stops and the latest nanoe-G operation status
is saved.
Indicator
o When nanoe-G starts, nanoe-G indicator ON (at Indoor Unit and Remote Control).

o During nanoe-G individual operation, if power failure occurs, after power resumes, nanoe-G individual
operation resumes immediately.
o During combination operation, if power failure occurs, after power resumes, combination operation resume
immediately.
Error detection control
When nanoe-G indicator blinks, it indicates error listed below:
o nanoe-G connector at main PCB open
o nanoe-G connector at main PCB open
Judgment
method
During nanoe-G operation, nanoe-G connector at main PCB is opened.
Troubleshooting
method
Connect the connector or stop operation to cancel the blinking.
o Abnormal discharge error
Judgment
method
During nanoe-G operation, the nanoe-G system has abnormal discharge due to short-circuit caused
by water or dust adhesion and so forth, with Lo-feedback voltage (at microcontroller).
When abnormal discharge occurred, every 30 minutes the unit supplies power to the nanoe-G
system.
When abnormal discharge occurs for 24 times continuously, nanoe-G indicator blinks.
o Troubleshooting
method
Press nanoe-G button or OFF button to stop the operation and check the nanoe-G connector at PCB.
After that, press nanoe-G button again to confirm the nanoe-G indicator do not blinks.
The 24 timer counter will be clear after 10 minutes of normal operation or when operation stops.
o Error reset method
Press OFF button to OFF the operation.
Press AUTO OFF/ON button at indoor unit to OFF the operation.
OFF Timer activates.
Power supply reset.
