<Change on wired remote controller>
When wireless remote controller is used
Change the external static pressure setting with the
DIP switch on the receiver section P.C. board.
For details, refer to the manual of the wireless
remote controller kit.
The settings can also be changed with the switch on
the indoor microcomputer P.C. board.
∗
However, once the setting is changed, setting to
0001 or 0006 is possible but setting to 0000
requires a setting data change to 0000 using the
wired remote controller (separately sold) with the
normal switch setting (factory setting).
To restore the factory settings
To return the DIP switch settings to the factory
settings, set SW501-1 and SW501-2 to OFF, con-
nect a separately sold wired remote controller, and
then set the data of CODE No. [5d] to “0000” in
“Setup of external static pressure” on this page.
