This should be interpreted as follows:
  5A   Incoming data
  05   Bytes that follow
  08   Function bitmap 00001000 => 4th byte following (i.e., 67)
       is a function byte.
  31   Extended Type/Function 31 => Extended Preset.
  3F   Preset value = 0x3F = 63 (scale 0-63)
  06   X10 encoded Unit code for Unit 1.
  67   Hi = 6 = House code A, Lo = 7 = Extended code
