2) If multiple air outlets and air inlets are included, adjust the airflow volume ratio of all of them
until they meet the design airflow ratio.
3) Make sure the address setting has been completed.
(2) The operation check will be completed in approximately three minutes if the settings have
been made correctly. The settings will be modified if they are out of the range of use
(maximum 30 minutes). If this is not completed within 31 minutes, check whether the air
speed is set to "H" or not.
(3) See Table 10-2, 10-3 or 10-4 and Fig. 10-2 for details on the relationship between the value
of item code "b0" and the external static pressure.
(4) When set in group control (connecting multiple indoor units with one wired remote
controller), set each indoor unit to item code "b0".
When amending the setting after selecting [b. Manual setting] (due to airflow path changes,
etc.), it is necessary to cancel [b. Manual setting] (change the dip switch). When [b. Manual
setting] has not been cancelled, [c. Manual setting] and [d. Auto airflow volume setting]
will be activated if selected, but [b. Manual setting] takes precedence when the power is
switched back on after power outages, etc.
(5) If this is not completed within 8 minutes, check the operation mode, air speed and air inlet
temperature.
(6) When set in group control (connecting multiple indoor units with one wired remote
controller), the test run operations display will disappear once the external static pressure
setting check or auto airflow volume control operation check have been completed for the
main unit. However, it is not possible to determine whether sub-units have completed. The
test run operation display will disappear after one hour even if the external static pressure
setting check or auto airflow volume control operation check have not been completed.
CAUTION
● Be sure to check that the external static pressure is within the range for use and then
make the setting. Failure to observe this may result in insufficient airflow or water
leakages. See Fig. 10-2 for the external static pressure setting range.
● There are cases in which automatic variable dampers and other mounted items may
trigger the P12 alarm on systems that modify the external static pressure when the
auto airflow volume control operations or setting check operations are carried out
if high external static pressure is lowered. In this event, lower the dampers, etc., so
that the external static pressure reaches its lowest level, and then carry out the auto
airflow volume control operations or setting check operations.
● Be sure to set the [External Static Pressure Setting] once again after amending the
airflow path for the duct or air outlet after setting the external static pressure.
● Set the air inlet temperature within the range for use. The auto airflow volume control
will not function if the air inlet temperature is over 45°C or if operation is other than
fan mode.
