External static pressure settings
Set up a tap change based upon the external static pressure of the duct to be connected.
To set up a tap change, follow to the basic operation procedure (
• Specify [5d] to the CODE No. in procedure

• For the SET DATA of procedure
, select a SET DATA of the external static pressure to be set up from the
following table.
<Change on wired remote controller>

With a remote controller-less system (group control)
Besides the switching method using the wired remote controller as a way to establish the external static pressure
switching is also possible by changing over the jumper block settings on the indoor P.C. board as shown in the
following table.
* However, once these settings are changed, it is necessary to reset the SET DATA to 0001 that placing the
jumper block back to the factory default position and rewriting the SET DATA back to 0001 with wired remote
controller (sold separately).
• Change over the jumper blocks on the indoor P.C. board, and select the desired setting.

To secure better effect of
heating
When it is difficult to obtain satisfactory heating due to
installation place of the indoor unit or structure of the
room, the detection temperature of heating can be
raised. Also use a circulator or other machinery to
circulate heat air near the ceiling.
