VRF SYSTEMS Indoor Unit
•High Static Pressure Ducted (S-180, 224, 280ME2E5)
Choose one of the methods (selection of “a”, “b”, “c” within the range of dotted line as shown in the flowchart below)
and make settings.
a. No setting changes:
When using as it is factory preset at shipment.
(If resetting after external static pressure setting once, it might be different from factory preset.)
b. Manual setting (on PCB):
This is static pressure setting excepting factory preset at shipment. Dip switch select method.
c. Manual setting (by wired remote controller):
Static pressure setting excepting factory preset at shipment.
Flow of External Static Pressure
NOTE
(1) Refer to Table 2-9, 2-10, 2-11 and Fig. 2-10 for details on the relationship between the value of item code “5d”
and the external static pressure.
(2) When set in group control (connecting multiple indoor units with one wired remote controller), set each indoor
unit to item code “5d”.
When amending the setting after selecting [ b. Manual setting] (due to airflow path changes, etc.), it is
necessary to cancel [b. Manual setting] (switching OFF positions).
When [b. Manual setting] has not been cancelled, [c. Manual setting] will be activated if selected, but [b. Manual
setting] takes precedence when the power is switched back on after power outages, etc.
CAUTION
l Make sure the external static pressure is in a range of specifications.
Then proceed the external static pressure setting.
Improper settings can cause noise, a shortage of airflow volume and water
leakage.
Refer to Fig. 2-9 for the external static pressure setting range.
l 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.
