（1）開機后，紫燈持續(xù)顯示2分鐘后，風(fēng)扇在高速模式下運行。空氣質(zhì)量傳感器預(yù)熱結(jié)束，開始檢測空氣質(zhì)量。（實際測3.5分鐘）

（2）當(dāng)空氣質(zhì)量傳感器檢測到空氣質(zhì)量差時，指示燈仍然顯示紫色，并持續(xù)30秒。

（3）檢測空氣質(zhì)量，如檢測結(jié)果仍然是差，則仍然執(zhí)行第2步步驟。如檢測到空氣質(zhì)量為良（或優(yōu)）指示燈顯示綠色，并持續(xù)20秒。

（4）檢測氣質(zhì)量，如檢測結(jié)果為差指示燈顯示為紫色，并從第2步開始向下執(zhí)行；如檢測結(jié)果為良，則從第3步開始向下執(zhí)行；檢測結(jié)果為優(yōu)，則指示燈顯示藍色。

（5）當(dāng)空氣質(zhì)量傳感器檢測到差，步驟從第2步到第5步依次循環(huán)執(zhí)行。
