Using the wire controller to set external static pressure (some
models)
• You can use the unit's automatic airflow adjustment function to set
external static pressure.
• Automatic airflow adjustment is the volume of blow-off air that has
been automatically adjusted to the quantity rated.
1. Make sure the test run is done with a dry coil. If the coil is not dry,
run the unit for 2 hours in FAN ONLY mode to dry the coil.
2. Check that both power supply wiring and duct installation have
been completed Check that any closing dampers are open. Check
that the air filter is properly attached to the air suction side passage
of the unit.
3. If there is more than one air inlet and outlet, adjust the dampers so
that the airflow rate of each air inlet and outlet conforms with the
designed airflow rate. Ensure the unit is in FAN ONLY mode. Press
and set the airflow adjustment button on the remote control to
change the airflow rate from H or L.
4. Set the parameters for automatic airflow adjustment. When the air
conditioning unit is off, perform the following steps:
• Press "COPY".
• Press "+" or "-" to select the AF.

• Press "CONFIRM". The air conditioning unit will then start the fan
for automatic airflow adjustment.
ON will flash when the fan is on during
automatic airflow adjustment.
