Operation About natural air function Natural air means that the air conditioner runs with analog natural airflow and automatically changes air speed to avoid human discomfort due to long exposure to strong wind. About human sensing function Human sensing function is to detect indoor human activity with a human sensor. After human sensing is actuated, if the unit keep detecting no human activity for 20 min, it will automatically enters standby (monitor) status, during which the unit will automatically start and resume operation if sensing human activity. About light sensing function Light sensing function is to detect indoor light intensity with a photosensor. After setting light sensing function, if darkness is continuously detected for 2 min, the unit will automatically change to sleep mode; the main machine will remain current operation conditions if darkness remains after 8 hrs. Anytime brightness is detected for 10 min, the unit will quit sleep mode and resume operation conditions before sleep running. Light sensing and human sensing could be actuated simultaneously, while human sensing is unavailable during light sensing. About intelligent operation During intelligent operation, the indoor human activity or light intensity is sensed through an intelligent sensor (human sensor, photosensor), and the unit runs as follows according to the room conditions: Human sensor (sensed)persons (sensed)no persons Photosensor (sensed)dark (sensed)bright Room conditions Running mode Night and with shading curtain Sleep continue ten minutes continue two minutes Day or night lamp light Resume operation continue twenty minutes in twenty minutes standby 1.At high ambient temperature, the human sensor may detect inaccurately or invalidly due to thermal airflow. 2.Please notice that itíll enter sleep mode when turning off the room lamps, during which sleep running continues even if people leave the room. 3.If light sensing and human sensing are both selected, when the photosensor detects ìdarkî, the air conditioner wonít change its running mode even the human sensor detects human activity. 4.The human sensor could detect animals such as dogs and cats as well as heat sources e.g. heaters and electric cookers. 21
