USING THE WIRED CONTROLLER TO SET
THE EXTERNAL STATIC PRESSURE
The automatic airflow control function can be used to set
the external static pressure.
Automatic airflow control acts on the amount of air
emitted, automatically adjusting it to the nominal amount.
– Make sure that the operating test is carried out
with the coil dry. If it is not, operate the unit for 2
hours in FAN ONLY mode to dry the coil.
– Make sure that the power supply has been wired
and the air duct has been installed and check that
any damper closures are open. Ensure that the air
filter is fitted properly to the air intake side of the
unit’s duct.
– If there are multiple air inlets and outlets, adjust the
dampers so that the airflow of each inlet and each
outlet complies with the nominal flow rate. Make
sure that the unit is in FAN ONLY mode. Press the
airflow control button on the remote control to
change the flow rate to H or L (high or low).
– Set the parameters for automatic airflow control.
When the air conditioning unit is switched off, carry
out the following steps:
- Press “COPY”.
- Press “+” or “-” to select the AF (airflow).

- Press “CONFIRM”. The air conditioning unit will
then start the fan for automatic airflow control.
The “ON” light flashes when the fan is
switched on during automatic airflow
control.

CAUTION DANGER
DO NOT adjust the dampers when the
automatic airflow control is active.
After 3 to 6 minutes, operation of the air conditioner will
stop once the automatic airflow control has finished
l
WARNING
– If there are no changes to the ventilation
after the automatic airflow control has
finished, reset the automatic airflow control
again.
– If there are still no changes to the ventilation,
contact an authorised dealer, especially if
this occurs after checking the outdoor unit
or if the unit has been moved to a different
location.
– Do not use the remote control for the
automatic airflow control if using auxiliary
fans, outdoor air handling unit or HRV
through the duct.
– If the ventilation has changed, reset the
automatic airflow control following the
above procedure.
