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
and filter settings, these settings can be changed by arranging the jumper block on the indoor unit micro computer
P.C. board as shown in the following table as well.
* However, once the setting is changed, it is necessary to reset the SET DATA to 0000 that placing the jumper
block back to the factory default position and rewriting the SET DATA back to 0000 with wired remote controller
(sold separately).
• Change over the jumper blocks on the indoor P.C. board, and select the desired setting.
Jumper block positions (CN112, CN111 and CN110 from the left)
* When the High-efficiency filter 65 or 90 is used, resistance of about 30 Pa is applied. Adjust the duct resistance
(external static pressure) of the duct to 40 Pa.
