1. The dotted lines show field wiring.
2. It is wiring for 1 refrigerant system at the time of shipping.
Change wiring and SW2, 3, 4 (No.1&No.2) as this figure in field
when you change it to 2 refrigerant circuit
3. Set up the address of No.1 board in the odd number, and set up the
address of No.2 board in the even number.
But, set up the address of the No.2 board in the No.1 board +1.
4. The outdoor unit to which the indoor unit is connected with the
transmission line, the address of the outdoor unit should be the
indoor unit +50.
5. Mark indicates terminal bed, connector, board insertion connector
or fastening connector of control board.

How to connect in case of 2 refrigerant circuit.
Remove the LEV1B connector
from AD.B. board, and
connect it to CN60 of
I.B.2 board.
Connect a connector to
CN3A, CN2M of I.B.2
board.
