Vertical swing louver direction control

[lumixen]

According to Hitachi operation manuals for their central managing stations, it should be possible to set the louver direction.

I found that enabling automatic swing mode affects addresses P0007 (RW), P0008 (RO), P0009 (RO), P000A (RO), P0013 (RW), and P0014 (RW). Sending commands to P0013 also changes the louver direction to some extent (for example, it can turn off the automatic swing mode).

However, it feels like I have reached a dead end, as controlling it may require a specific sequence of commands or a particular pattern.

I welcome any ideas from the community or additional debug data that could provide insights into the louver direction configuration.
