ith a remote controller-less system (group control)
Besides the switching method using the wired remote controller as a way to establish the high-ceiling and filter
settings, switching is also possible by changing over the short plug settings on the indoor printed circuit board as
shown in the following table.
* However, once these settings are changed, 0001 can be set easily, but bear in mind that to return to the 0000 data,
it will be necessary to change the short plugs over to the standard (factory setting) positions and rewrite the data
back to SET DATA 0000 from the wired remote controller.
• Change over the short plugs on the indoor printed circuit board, and select the desired setting.

the following procedure.
Connect the indoor units by connecting the remote
controller inter-unit wires from the remote controller
terminal blocks (A/B) of the indoor unit connected with
a remote controller to the remote controller terminal
blocks (A/B) of the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual
attached to the outdoor unit.
