1.8 NIGHT SET Mode
Outline When the OFF timer is set, the NIGHT SET Mode is automatically activated. The NIGHT SET
Mode keeps the airflow rate setting.
Detail The NIGHT SET Mode continues operation at the target temperature for the first one hour, then
automatically raises the target temperature slightly in the case of cooling, or lowers it slightly in the
case of heating. This prevents excessive cooling in summer and excessive heating in winter to
ensure comfortable sleeping conditions, and also conserves electricity.
