these modes, the air conditioner controls the set

the Cool mode or lower in the Heat mode than
the current temperature. Press the Temperature
button on the remote control to change the set
temperature.
• Check whether the air filter is blocked with dirt.

installed near obstacles. Remove the coverings and
obstacles.
