1.4.11 Automatic Airflow Adjustment
Make external static pressure setting automatically using automatic airflow adjustment
(11 (21)-7), or manually using external static pressure settings (13 (23)-6).
The volume of blow-off air is automatically adjusted to the rated quantity.
Make settings before performing the test operation of the outdoor unit.
Setting procedure
1. Make sure that electric wiring and duct construction have been completed. In particular, if
the closing damper is installed on the way of the duct, make sure that it is open. In addition,
make sure that a field-supplied air filter is installed within the air passageway on the suction
port side.
2. If there are multiple blow-off and suction ports, adjust the throttle part so that the airflow
volume ratio of each suction/blow-off port conforms to the designed airflow volume ratio. In
that case, operate the unit with the operation mode "fan". When you want to change the
airflow rate, adjust it by pressing the airflow rate control button to select High, Middle or Low.
3. Make settings to adjust the airflow rate automatically. After setting the operation mode to
"fan", enter the field setting mode while operation is stopped and then select the Mode No.
"(21) (11 for batch setting)", set the First Code No. to 7 and the Second Code No. to
03
. After
setting, return to the basic screen (to the normal mode in the case of a wireless remote
controller) and press the ON/OFF button. Fan operation for automatic airflow adjustment will
start with the operation lamp turned ON. Do not adjust the throttle part of the suction and
blow-off ports during automatic adjustment. After operation for approximately one to fifteen
minutes, airflow adjustment automatically stops with the operation lamp turned OFF.
4. After operation stopped, make sure that the Second Code No. is set to
02
as in the following
table by indoor unit with the Mode No. of (21). If operation does not stop automatically or the
Second Code No. is not set to
02
, return to the step 3. above to make settings again.
: Factory setting
1. Make sure that the external static pressure is within the range of specifications before making
settings. If it is outside the range, automatic adjustment fails, which may cause an insufficient
airflow volume or leakage of water.
2. If the air passageway including duct or blow-off ports is changed after automatic adjustment,
make sure to perform automatic airflow adjustment again.
