7-5. SYSTEM CONTROL
7-5-1. Example for the System
• Example for wiring control cables, wiring method and address setting, permissible lengths, and the prohibited items are listed
in the standard system with detailed explanation.
A. Example of a M-NET remote controller system (address setting is necessary.)
Example of wiring control cables
Wiring Method and Address Setting
• 1
M-NET remote controller for
each M-NET control indoor unit
• There is no need for setting
the 100 position on the M-NET
remote controller.
1. Standard operation
2. Operation using 2 M-NET remote controllers
• Using 2 M-NET remote
controllers for each M-NET
control indoor unit
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
cable block (TB5) of each M-NET control indoor unit
(M-IC). Use non-polarized 2-core wire.
b. Connect terminals M1 and M2 on transmission cable
terminal block (TB5) for each indoor unit with the termi
-
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.
3. Group operation
• Multiple M-NET control indoor
units operated together by 1
M-NET remote controller
a. Same as above a
b. Same as above b
c. Set address switch (on outdoor unit P.C.B) as
shown below.
a. Same as above a
b. Connect terminals M1 and M2 on transmission cable termi-
nal block (TB5) of the M-IC main unit with the most recent
address within the same M-NET control indoor unit (M-IC)
group to terminal block (TB6) on the M-NET remote controller.
c. Set the address setting switch (on outdoor unit P.C.B) as
shown below.
d. Use the M-NET control indoor unit (M-IC) within the
group with the most functions as the M-IC (Main) unit
.
Combinations of 1 through 3 above are possible.
