Fujitsu AOU36RLXFZ Service Instruction

The maximum value of the indoor fan speed is set as shown in Fig 6, based on the detected
temperature by the indoor heat exchanger sensor in heating mode.

01-09
5. HEATING OPERATION
Switch the airflow [Auto], and the indoor fan will run according to a room temperature,
as shown in Fig 5.
On the other hand, if switched in [Hi] [Quiet], the indoor fan will run at a constant airflow
of [Heat] operation modes Quiet, Lo, Me, Hi, as shown in Table 2.
