AUTO operation

When you set the air conditioner in AUTO mode, it will 
automatically select cooling, heating(cooling/heating 
models only), or fan only operation depending on what 
temperature you have selected and the room

automatically round the temperature point set by you.
If the AUTO mode is uncomfortable, you can select 
desired conditions manually.

SLEEP operation

This characteristic maintains both enery saving and 
comfort in night operation.
