Sleep Mode; Quiet Function; Eco+ Function - Daikin FTKB09AXVJU Service Manual

2.7 Sleep Mode

SLEEP Mode can be activated through the remote controller to keep the thermal comfort while sleeping.
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.
