SiBE121123_A Function of RA Indoor Unit
Function and Control 70
2. Motions (for example: in cooling)
When the microcomputer does not have a signal from the sensor in 20 minutes, it judges
that nobody is in the room and operates the unit in temperature shifted from the target
temperature. (Cooling / Dry : 2°C higher, Heating : 2°C lower, Auto : according to the
operation mode at that time.)
In case of FAN operation, the fan speed reduces by 60 rpm.
3. Airflow direction in 2-area INTELLIGENT EYE operation
Detection method: The opposite area of detected area is set as the target direction.
1. Detection signal ON in both area A and B: Shift the airflow direction to area B (left side)
2. Detection signal ON in area A: Shift the airflow direction to area B (left side)
3. Detection signal ON in area B: Shift the airflow direction to area A (right side)
4. Detection signal OFF in both area A and B: No change
* When the detection signal is OFF for 20 minutes in both area A and B, the unit starts energy
saving operation.
Others
For dry operation, you cannot set the temperature with remote controller, but internally the
