The PM2.5 sensor lamp is always
blue and does not change
The PM2.5 concentration value
displayed with the AIR MONITOR
indicator is always “---”, and Daikin
eye remains blue and does not
change.
• If the displayed value remains “---” even after you set the AIR MONITOR
indicator to display the concentration of PM2.5, the PM2.5 sensor may be
defective.
¼ Contact the place of purchase.
There is an odour but the odour
sensor lamp remains blue • Did an odour already exist around the time you inserted the power
supply plug?
¼ The basic sensitivity of the odour sensor will be determined by odour
levels in the fi rst minute (approx.) after the power supply plug is inserted
every time. Page 10
To adjust the basic sensitivity of the odour sensor, unplug the power supply
when the air is clean (odour-free), wait at least 5 seconds, then re-insert the
power supply plug and turn the unit on again. This process adjusts the
reference odour level that determines the sensitivity of the odour sensor.
