Wiring Method and Address Setting
a. Use feed wiring to connect terminals M1 and M2 on
transmission cable block (TB3) for the outdoor unit
(OC) to terminals M1 and M2 on the transmission
M-IC
cable block (TB5) of each M-NET control indoor unit
(M-IC). Use non-polarized 2-core wire.
(02)
b. Connect terminals M1 and M2 on transmission cable
TB5 TB15
terminal block (TB5) for each indoor unit with the termi-
1 2
nal block (TB6) for M-NET the remote controller (M-NET
RC).
c. Set the address setting switch (on outdoor unit P.C.B)
as shown below.

Range Setting Method
—
Use the smallest address of all
the indoor unit plus 50.
101 to 150 Indoor unit address plus 100
Range Setting Method
001 to 050 —
Use the smallest address of all
the indoor units plus 50.

151 to 200 Indoor unit address plus 150
Range Setting Method
Use the smallest address within
001 to 050
the same group of M-NET control
indoor units.
Use an address, other than that of
the M-IC (Main) from among the units
001 to 050
within the same group of indoor units.
This must be in sequence with the
M-IC (Main).
Use the smallest address of all the
051 to 100
M-NET control indoor units plus 50.
Set at an M-IC (Main) address
101 to 150
within the same group plus 100.
