ty brightness UVnano Description Option A function to control the air quality display brightness of the indoor unit. ON/OFF The UVnano function is to steril-

ize the fan or the filter by using a UV LED at regular time intervals when the indoor unit is working. ON/OFF You can check the fine dust filter status and reset the filter usage time. You can check the pre-filter status and reset the filter usage time. The used and remaining amount are for reference, and the actual filter status may vary depending on the installation environment and usage conditions. When dust is caught in the filter, the airflow decreases and the electric bill is high, so be sure to clean or replace the filter when it is time to clean or replace it. The fine dust filter (HEPA filter) check mark will not be cleared unless you specifically clear it. The pre-filter check mark will be cleared after a certain time even if you dont specifically clear it.
