Infrared sensor checking points
Check assembly
·Is the assembly position and appearance about the sensor cover and the sensor ok?
⇒Check if there is dirt or nick on the cover.
·Is the assembly about the sensor unit ok?
⇒Check the assembly position between the sensor unit and the dew pan.(2 lugs)
·Is the assembly about the infrared sensor P.W.B. ok?
⇒Check the assembly position of the P.W.B..(lugs×2, screws×2)
Note:
※The infrared sensor detects changes to the infrared generated by human bodies.
If there is dirt or nick on the surface of the sensor cover or the sensor, it will distube the detection of the infrared sensor.
※If the assembly position is incorrect,the area detected will be incorrect so that
it will distube the operation of the dynamic air deflection function.
Check installation position of the air conditioner
·Is the installation position of the indoor unit correct?
⇒Please refer to the installation manual to check and correct.
Note:
※If the installation position of the indoor unit is incorrect,it will mislead
the detection to the room area and the airflow direction.
Set the detection speed of the infrared sensor
·There are 2 detection speeds:"standard"(by intervals of 15"～3')and "slow"(by intervals of 1'～10').
The remote controller is set to the standard speed by default.
·When the detection speed of the sensor is too high,set the detection speed to "slow".
(When people and pets in the room behave frequently,resulting in frequent changes to the airflow direction.
·In addition to "standard"and "slow"modes,you can also fine tune the detection speed of the sensor.
Caution:
※The infrared sensor detects changes to the infrared generated by human bodies.
Therefore,the accuracy of infrared sensor may be affected negatively in the following cases:
·The activity level is very low(reading,watching TV,etc.)or human bodies are blocked by a screen,cabinet,
or glass board.
·The indoor temperature is very high and exceeds or approaches the human body temperature(when the refrigeration just
begins).
·The person wears thick clothes and turns his/her back to the air conditioner.
·Curtains or plant leaves swing due to pet movement or airflow.
