  +8/10°C Heat operation provides heating at low setting temperature in unoccupied houses during winter for the 

purpose of protecting equipments or housing appliances which may be destroyed by the extreme cold weather. 

  This operation can be ON by pressing the +8/10°C heat button on the remote control. 

  Two temperature settings are available, which are; 

o  8°C (Pressing TEMP down button at the remote control) 
o  10°C (Pressing TEMP up button at the remote control) 

  During the operation of this mode; 

o  The indoor fan speed will remain at Hi fan tap all the time included deice process. 
o  Powerful operation, Auto Comfort, Quiet operation, Econavi operation and Fan Speed selection are disabled. 
o  Cold draft prevention control is disabled. 

 Control 

condition; 

 

 

 
NOTE: 
+8/10°C HEAT set temperature follows previously fixed set temperature (+8°C or +10°C). 
But after battery reset, (default condition) set temperature always start with +8°C. 

 
  Caution! 
If the indoor temperature constantly is less than 0°C (Door, windows not close properly), the error code F11 may 
occur. This is because in open area, the indoor pipe sensor will misjudge operation condition and will give error code.

  Area of human availability, activity level and absent is judged based on pulses by using infrared sensor. The 

internal setting temperature shift, fan speed, horizontal and vertical airflow direction are adjusted in order to 
provide comfort environment while maintain the energy saving level. 

 
  AUTO COMFORT start condition: 

o  When AUTO COMFORT button is pressed. 

 

  AUTO COMFORT stop conditions: 

o  When AUTO COMFORT button is pressed again. 
o  When unit is OFF by OFF button. 
o  When unit is OFF when OFF TIMER activates. 
o  When unit is OFF by AUTO OFF/ON button at indoor unit. 
o  When POWERFUL, QUIET and ECONAVI operation activates. 
o When 

◄► button is pressed. 

o  When FAN SPEED button is pressed. 

 
  ECONAVI start condition: 

o  When ECONAVI button is pressed. 

 

  ECONAVI stop conditions: 

o  When ECONAVI button is pressed again. 
o  When unit is OFF by OFF button. 
o  When unit is OFF when OFF TIMER activates. 
o  When unit is OFF by AUTO OFF/ON button at indoor unit. 
o  When POWERFUL, QUIET and AUTO COMFORT operation selected. 
o When 

◄► button is pressed. 

o  When FAN SPEED button is pressed. 

  Area of human availability, activity level and absent is judged based on pulses by using infrared sensor. The 

internal setting temperature shift, fan speed and horizontal airflow direction are adjusted in order to provide 
comfort environment while maintain the energy saving level. 

  Human activity judgment is as following: 
 

 

47 

 

 

 

  Presumption flow of human position. 

o Detection 

outline. 

 

 

 

  The signal from Infrared sensor will be log to human activity database for further analysis. 

  According to Area of Living, frequency of activity, the system will analyze the human position away from the 

indoor unit. 

  Human Activity Level is judged based on the frequency of pulses detected by the infrared sensor within a 

timeframe. The activity level will be categorized into High, Normal or Low level. 

  When a pulse is detected within this timeframe, the status of human presence is judge. 

  When there is no signal detection continues for 40 minutes or more or the result of activity amount status is "Low" 

consecutively for 5 cycles the status of human absence is judged. 

  Human presence status shall be determined based on the human presence status of each area. 

  When all area has been detected absent for more than 120 minutes then it will judge as absence. 

48 

  The system is able to judge area of living according to human activity database, classified as following: 

o  (Zone I ) Living Area - In front of television, dining table, etc. 
o  (Zone II) Walkway - Human detection is relatively less. 
o  (Zone III) Non-Living Area - Near windows, wall, etc. 

  By default, the system will judge the indoor unit installation position according to human activities and will reset 

the louver center position: 
o  Non-Living Area at Position A - Indoor unit is installed at left side of the room, louver center position set to 

right side. 

o  Non-Living Area at Position C - Indoor unit is installed at right side of the room, louver center position set to 

left side. 

o  Other than above - Indoor unit is installed at center of the room, louver position set to center. 

  Every 4 hours, the Target Area and Position Judgment will restart. 

  If the indoor unit installation position is set by remote control, the above judgement will be ignored. 

  Cooling Dual Sensor
