When there is no signal from the motion sensor in 20 minutes, the microcomputer judges that
nobody is in the room and operates the unit at a temperature shifted from the target
temperature. (Cooling/Dry: 1 ~ 2°C (1.8 ~ 3.6°F) higher, Heating: 2°C (3.6°F) lower, Auto:
according to the operation mode at that time.)
Note: For dry operation, the target temperature is shifted internally. The temperature cannot be set with
the remote controller.
