Don't know the device but I would call those switches - toggle switches and I am guessing that whatever you set them too they would have to match the ones set inside the fan and the ones set in the remote.
Think of it as a 2 x 4 x 6 x 8 x10 equals 32 possible settings it could be .
lets say down/ off = 0 and up/ on =1
try each combination logically
0 0 0 0 0
0 0 0 0 1
0 0 0 1 0
0 0 0 1 1
0 0 1 0 0

repeat first 16 combinations with first switch set as on
