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