12.1.10 External Static Pressure Setting
For middle static pressure duct type indoor units, the ventilating resistance so-called "external static pressure"
becomes greatly different depending on the connected duct length, shape, number of air outlet ports and types of
filters.
When installing this unit, be sure to carry out the external static pressure setting in order to operate in the rated
airflow volume.
Choose one of the following methods from "a", "b", "c" or "d" as shown in the flow chart (within the dotted lines) and
then make the setting accordingly.
a. No setting modification:
Use-as-is at shipment (there are cases in which the setting may differ from the shipment setting when reset after
once setting the external static pressure.)
b. Manual setting (set with the indoor unit control PCB):
For high static pressure. Switching method with the short-circuit connector.
c. Manual setting (set with the wired remote controller):
Low static pressure ~ high static pressure
d. Auto airflow volume setting (set on the wired remote controller):
Air outlet volume is automatically adjusted to the rated airflow volume with the auto airflow volume control
operation.
