11.13.1.3 Area of Living Classification Judgment
• The system is able to judge area of living according to human activity database, classified as following:
Living Area – In front of television, dining table, etc.
Walkway – Human detection is relatively less.
Non-Living Area – near windows, wall, etc.
11.13.1.4 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.
11.13.1.5 Target Area and Position Judgment
• The system will judge the indoor unit installation position according to human activity Non-Living Area:
Non-Living Area at Position A – Indoor unit installed at left side of the room.
Non-Living Area at Position C – Indoor unit installed at right side of the room.
Other than above – Indoor unit installed at center of the room.
• Every 4 hours, the Target Area and Position Judgment will restart.
11.13.1.6 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.
11.13.1.7 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:
Horizontal airflow direction louver position
Target area
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
Higher Activity level ≈ 60 seconds
1 level
Lower Activity level ≈ 30 seconds
Higher Activity level ≈ 60 seconds
Cooling
2 levels
Lower Activity level ≈ 8 seconds
• 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
Hi ≈ 45 seconds
Me ≈ 30 seconds
Cooling
Lo ≈ 20 seconds
• When 3 activity areas have same activity level, the horizontal airflow direction louver will swing left and right.
