2.3 Using the wire controller to set external static pressure
• 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. Make sure 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:
- When the unit is turned off, hold the MODE button and
FAN button down together for three seconds. (“AF” indicator flashes for 3 times.)
- Press “
” or “
” to select the AF.
- Press “MODE”. The air conditioning unit will then start the fan for airflow automatic adjustment.
After 3 to 6 minutes, the air conditioning unit stops operating once automatic airflow adjustment has finished.
Caution: DO NOT adjust the dampers when automatic airflow adjustment is active.
Caution:
• If there is no change after airflow adjustment in the ventilation paths, be sure to reset automatic airflow adjustment.
• If there is no change to ventilation paths after airflow adjustment,contact your dealer, especially if this occurs after
testing the outdoor unit or if the unit has been moved to a different location.
• Do not use automatic airflow adjustment with remote control,if you are using booster fans, outdoor air processing
unit, or a HRV via duct.
• If the ventilation paths have been changed, reset airflow automatic adjustment as described from step 3 onwards.
