11. Humidity Sensor
If the humidity sensor has problem such as sensor open or short, no error display is shown at outdoor
unit.
Normally LGMV shows humidity ratio such as below display box of LGMV.
However, if the humidity sensor open/short occurred, it displays as "0".
In case of the sensor fault occurred, the system is operated not as the dual sensing SLC (Temperature
+ Humidity) but as the SLC (Only Temperature)
This means that system is normally operated without humidity function even if humidity sensor has
problem.
