I stumbled across this AC model and have been experimenting a bit with the remote. It does seem to use a 64 bit protocol that's different from the Delonghi_AC protocol that's already supported in the library. I followed the IR and AC guides in the wiki and created a spreadsheet. There's an extract of the manual and a picture of the remote in the spreadsheet. Can't dedicate more time to this right now so maybe someone else can take a look.
