NN is just a shorthand for 01 or 02 or 03 or 04 ect.
In programming go to PROGRAMMES, then Choose 3 for example. Now go to used zones, scroll thru and say 05 is the garage press 5 and it will change to yes. Then set up timers and entry exits types. Job done.
Then go to programe 1 and tell it 5 is also used.
Should be it
