Night Set Mode
When the OFF timer is set, the Night Set circuit automatically activates.
The Night Set circuit maintains the airflow setting made by users.
The Night Set
Circuit
The Night Set circuit continues heating or cooling the room at the set temperature for the first
one hour, then automatically raises the temperature setting slightly in the case of cooling, or
lowers it slightly in the case of heating, for economical operations. This prevents excessive
heating in winter and excessive cooling in summer to ensure comfortable sleeping conditions,
and also conserves electricity.

In case of 20-35 Class, the temperature rises once.
