To provide quiet heating operation compare to normal operation. 
 
B. Control condition 
a.  Quiet operation start condition 
o  When “FAN SPEED/QUIET” button at remote control is pressed continuously until QUIET will be shown 
on remote control display. 
 
b.  Quiet operation stop condition 
1  When one of the following conditions is satisfied, quiet operation stops: 
a.  POWERFUL button is pressed. 
b.  Stop by OFF/ON switch. 
c.  Timer “off” activates. 
d.  When FAN SPEED/QUIET button is pressed again and fan speed is change to Low. 
e.  Sleep mode timer delay OFF. 
2  When quiet operation is stopped, operation is shifted to normal operation with previous setting. 
3  When operation mode is changed, quiet operation is shifted to quiet operation of the new mode. 
4  During quiet operation, if timer “on” activates, quiet operation maintains. 
5  After off, when on back, quiet operation is memorized. 
 
C. Control contents 
1  Fan speed is changed to QLo. 
14.11   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. 
14.12   nanoe
™ 
X Operation 
  Generate nanoe™ X (water wrapped ion particle) to moisturize skin, provide deodorization & sterilization effect. 
 
  nanoe™ X operation start condition 
o  During unit running at any operation mode, if nanoe™ X operation is activated, combination operation 
(operation mode + nanoe™ X operation) starts. 
o  During unit is OFF, if nanoe™ X operation is activated, nanoe™ X individual operation starts. 
 
  nanoe™ X operation stop condition 
o  When OFF/ON button is pressed to stop the operation. 
o  When nanoe™ X button is pressed. 
o  When OFF Timer activates. 
 
  nanoe™ X operation pause condition 
o  When indoor fan stop (during deice, odor cut control, thermostat off, etc.). nanoe™ X operation resume after 
indoor fan restarts. 
o  When indoor intake temperature ≥ 35°C and ≤ 5°C. nanoe™ X operation resume after indoor intake 
temperature < 35°C or ≥ 5°C continuously for 6 minutes. 
 
  Indoor fan control 
o  During any operation mode combines with nanoe™ X operation, fan speed follows respective operation 
mode. However, nanoe™ X system enabled when fan speed ≥ 360 rpm to ensure proper negative ion 
distribution, nanoe™ X system disabled when fan speed < 360 rpm. 
o  During nanoe™ X individual operation, fan speed follow remote control setting. Auto Fan Speed for  
nanoe™ X individual operation is cooling medium fan. Powerful & Quiet is disabled during nanoe™ X. 
 
  Airflow direction control 
o  During any operation mode combines with nanoe™X operation, airflow direction follows respective operation 
mode. 
o  During nanoe™ X individual operation, Air Swing follow remote control setting.
