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 the case of cooling, or lowers the target
temperature 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.
