Yes, it is an really great custom driver that @cybrmage developed. It supports all the Fujitsu (and other brands) mini-split settings. It sends IR signals to the unit. I am using custom attributes in the RM code, and all I saw available for this parameter was using one of the drop-down options. Then again, I may have missed something... It has happened before!
