Sleep Mode

Outline SLEEP Mode can be activated through the remote controller to keep the thermal comfort while
sleeping.
Details SLEEP Mode continues operation at the target temperature for the first hour, then automatically
raises the target temperature slightly in case of cooling, or lowers it slightly in case of heating.
This prevents excessive cooling in summer and excessive heating in winter to ensure
comfortable sleeping conditions and also saves electricity.
