Installation Manual
FAN MANUAL SETTING
Daikin FDYQ-L Series Ducted Fan Coil units employ a high efficiency DC Fan Motor operating in combination
with a Daikin proprietary microprocessor based motor management system. The DC Fan Motor contains multiple
motion sensor devices that monitor the motor’s rotation and speed. The output from these devices is constantly
compared against target data in the motor management system which subsequently makes adjustments to the
motor input waveform to maintain the target motor speed.
To match the airflow requirements to the individual installation, the target fan motor speed can be commissioned
via the remote control to one of fifteen individual settings as described below. The default factory setting is the
highest speed (ie 15) so if you experience excessive airflow during post installation checks please follow the field
setting instructions to set a lower airflow.
Please note that any change to the fan motor speed via the method described below is applied across all 3 user
selectable speeds (ie High, Medium, Low).
