Dip Switch Setting
Note: communication protocol between indoor and outdoor units
The new communication protocol is faster than the old communication and its control content is more than the
old one.
The indoor PCB 151800113, 151800161, 0151800161B, 0151800227, 0151800244, 0010451751AF,
0151800141A, 0010451751AE and 151800141 are new communiction protocol.
The indoor PCB 151800086 and 0010451181A are old communiction protocol.
Old communication protocol indoor PCB can't connect with new communiction protocol outdoor, so if this
outdoor unit connect with old communication protocol indoor, need set the dip switch BM2-6 to ON position.
