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