Wiring Method
Address Settings
a. Always use shielded wire when making connections between the outdoor unit (OC) and the M-NET control indoor unit
(M-IC), as well for all OC-OC, and IC-IC wiring intervals.
b. Use feed wiring to connect terminals M1 and M2 and the ground terminal on the transmission cable terminal block (TB3)
of each outdoor unit (OC) to terminals M1 and M2 on the terminal S on the transmission cable terminal block of the
M-NET control indoor unit (M-IC).
c. Connect terminals 1 and 2 on the terminal block for MA remote controller line (TB15) on the indoor unit (IC) to the ter-
minal block on the MA remote controller (MA). (Nonpolarized two-wire).
d. Connect together terminals M1, M2 and terminal S on the terminal block for centralized control (TB7) for the outdoor unit (OC).
e. DO NOT change the jumper connector CN41 on outdoor multi controller circuit board.
f. The earth processing of S terminal for the centralized control terminal block (TB7) is unnecessary. Connect the termi-
nal S on the power supply unit with the earth.
g. Set the address setting switch as follows.
h. The group setting operations among the multiple M-NET control indoor units is done by the M-NET remote controller
(M-NET RC) after the electrical power has been turned on.
Unit
Range
Setting Method
M-IC (Main)
01 to 50
Use the smallest address within the same group of indoor units.
M-IC (Sub)
01 to 50
Use an address, other than the M-IC (Main) in the same group of M-NET
indoor units. This must be in sequence with the M-IC (Main).
OC
51 to 100
Use the smallest address of all the indoor units plus 50.
The address automatically becomes “100” if it is set as “01–50”.
M-NET RC (Main)
101 to 150
Set at an M-IC (Main) address within the same group plus 100.
M-NET RC (Sub)
151 to 200
Set at an M-IC (Main) address within the same group plus 150.
