SMMS 2-way Air Discharge Cassette Type
With 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.
