Detecting ofair quality( Whenthe air conditioner is on standby.)
(a) After the air conditioner stops operation, it will providespower to the air quality sensor intermittently todetect
the air quality and update theresistancereference (MAXR). The p
ower ofthe air quality sensor will beonfor 3
minutes after each 109 minutes.
During these3minutes, the air quality sensor will be in preheating process for 2 minutesand theother time is
for measuring theresistance.The air conditioner will compare the maximum resistance measured in this per
iod
with the maximum value in the previous 109 minutesand the bigger one will be selected as resistance
