Why does air conditioner keep operating after it is powered off?
After your air conditioner is powered off, there is some residual moisture
inside the conditioner. It operates for a while to eliminate the moisture,
so as to reduce the possibility of mould growth.
Why are the air conditioner functions non-adjustable?
If the display panel presents a centralized controller icon, the air
conditioner is locked. In this case, please contact the air conditioner
system administrator.
