External
static
pressure
settings
There are 2 ways to set external static pressure setting.
1) By DIP SW 501-1, -2 [FC [5D]=0000 (factory default) is necessary.]
Set the external static pressure setting with the DIP SW501-1, -2 on the indoor unit P.C. board as shown in
the table below.
2) By Wired remote controller
In this model, external static pressure setting can be set with FC data setting by wired remote controller.
By changing FC [5D] data, it is possible to set the external static pressure setting as shown in the table
below.
If FC[5D] is set to not 0000, external static pressure setting does not follow the positions of DIP SW501-1,-2.
At factory default, FC[5D] data is set to 0000.
