14.14.1.4 Human Position Analysis
According to Area of Living, frequency of activity and indoor unit intake temperature, the system will analyze the
human position away from the indoor unit.
14.14.1.5 Target Area and Position Judgment
The system will judge the indoor unit installation position according to human activity Non-Living Area:
o Non-Living Area at Position A – Indoor unit installed at left side of the room.
o Non-Living Area at Position C – Indoor unit installed at right side of the room.
o Other than above – Indoor unit installed at center of the room.
Every 4 hours, the Target Area and Position Judgment will restart.
14.14.1.6 Human Activity Level Judgment
Human Activity Level is judged based on the frequency of pulses detected by the infrared sensors within a
timeframe. The activity level will be categorized into High, Normal, Low level.
When a pulse is detected within this timeframe, the status of human presence is judged.
When there is no signal detection continues for 20 minutes or more, the status of human absence is judged.
14.14.1.7 Setting Position Judgment
According to installation position when there is only one activity area detected, the horizontal airflow direction
louver position is fixed according to chart below:
Target area
Horizontal airflow direction louver position
Left installation Center installation Right installation
A 3 2 2
B 1 1 1
C 5 5 4
Louver position refer to horizontal airflow direction control.
When 2 activity areas have been detected, according to Human Activity Level, the timing of horizontal airflow
direction louver steps at the targeted activity areas is judged.
Operation mode Activity level difference Louver stop time
Cooling
1 level
Higher Activity level ≈ 60 seconds
Lower Activity level ≈ 30 seconds
2 levels
Higher Activity level ≈ 60 seconds
Lower Activity level ≈ 8 seconds
Cooling
1 level
Higher Activity level ≈ 8 seconds
Lower Activity level ≈ 30 seconds
2 levels

When 3 activity areas have been detected, according to Human Activity Level the timing of horizontal airflow
louver steps at the targeted activity areas is judged.
Operation mode Activity level Louver stop time

When 3 activity areas have same activity level, the horizontal airflow direction louver will swing left and right.
