(3) Refer to Table 3-3 and Fig. 3-15 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] (disconnect short-circuit connector). 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 drive 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. Decisions on sub-unit complete are not possible. 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.
● 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. Refer to Fig. 3-15 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 static pressure of outdoor units when the auto airflow volume control operations or setting check operations
are carried out if high static pressure in the outdoor unit is lowered. In this event, lower the dampers, etc., so that the static
pressure in the outdoor unit 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 not in the fan mode.
3-6-1. How to Set on PC Board
1. Turn off the power breaker to halt the supply of electricity
to the PC board.
2. Open the lid of electrical equipment box and check where
the short-circuit pin on the indoor unit control PC board is
located (Fig. 3-14)
3. Short circuit the applicable short-circuit pin in accordance
with the selected short-circuit pin connected (Fig. 3-15).
30 Pa : TP3 (2P: yellow) short-circuit
20 Pa : TP1 (2P: red) short-circuit
* Use the short-circuit connector (2P: yellow) supplied.
