(3) See Table 1-11-1-2-2, 1-11-1-2-3 and Fig. 1-11-1-2-2 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. 1-11-1-2-2 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.
How to Set on Indoor Unit Control PCB
Table 1-11-1-2-1
1. Turn off the power breaker to halt the supply of electricity to the indoor unit control PCB.
2. Open the electrical component box cover, then check the indoor unit control PCB. (Fig. 1-11-1-2-1)
3. Change the dip switch (SW001) of the indoor unit control PCB according to the setting selected in Table 1-11-1-2-1.
