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
IC
cable block (TB5) of each indoor unit (IC). Use non-
02
polarized 2 wire.
b. Connect terminals M1 and M2 on transmission cable
TB15
terminal block (TB5) for each indoor unit with the
1 2
terminal block (TB6) for the remote controller (RC).
c. Set the address setting switch (on outdoor unit P.C.B)
as shown below.
