Controller method between indoor and outdoor has been changed. 3. Power supply method has been changed (change to supply from outdoor unit). 4. Power supply cord has been removed. 5. Indoor electronic control P.C. board has been changed. 6. Position of terminal block has been changed. 7. Indoor fan motor has been changed. ( AC O DC) 8. Indoor heat exchanger has been changed. 9. The horizontal vane motor unit has been changed. An external gear is added to the generalized stepping motor. The unit is structured so that the driving torque and stopping torque would increase. Generalized stepping motor NOTE: Do not remove the vane motor from the motor unit. Do not disassemble the horizontal vane motor unit. 10. The vertical vane motor unit has been added. An external gear is added to the generalized stepping motor. The unit is structured so that the driving torque and stopping torque would increase. Generalized stepping motor NOTE: Do not remove the vane motor from the motor unit. Do not disassemble the vertical vane motor unit. 11. Front panel driving motor unit which opens and closes the front panel has been added. Front panel opening/closing output gear NOTE: Do not disassemble the front panel driving motor unit. 12.
