Example of a group operation system with multiple outdoor units (Shielding wires and address setting are necessary.)
<Examples of Transmission Cable Wiring>
■
Refer to Fig. 6-6 from Fig. 6-2.
<Wiring Method and Address Settings>
a. Always use shielded wire when making connections between the outdoor unit (OC) and the indoor unit (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, M2
and terminal S on the transmission cable block of the indoor unit (IC).
c. Connect terminals 1 (M1) and 2 (M2) on the transmission cable terminal block of the indoor unit (IC) that has the most recent address within the same group to the terminal
block on the remote controller (RC).
d. Connect together terminals M1, M2 and terminal S on the terminal block for centralized control (TB7) for the outdoor unit (OC).
e. The jumper connector CN41 on the control panel does not change.
f. Connect shield ground of the indoor units transmission line to the shield (S) terminal of (TB3) and also connect (S) terminal to the screw (
E
or
F
) using attached lead wire.
Connect shield ground of the line between outdoor units and the centralized control system transmission line to the shield (S) terminal of (TB7).
g. Set the address setting switch as follows.
Unit
Range
Setting Method
M-IC (Main)
01 to 50
Use the most recent address within the same group of indoor units
M-IC (Sub)
01 to 50
Use an address, other than that of the IC (Main) from among the units within the same group of indoor units. This must be
in sequence with the IC (Main)
Outdoor unit
51 to 100
Use the most recent address of all the indoor units plus 50
* The address automatically becomes “100” if it is set as “01 - 50”.
M-NET RC (Main) *1
101 to 150
Set at an IC (Main) address within the same group plus 100
M-NET RC (Sub) *1
151 to 200
Set at an IC (Main) address within the same group plus 150
MA RC
—
Unnecessary address setting (Necessary main/sub setting)
*1 An ME remote controller cannot be connected to a system that contains a branch box.
h. The group setting operations among the multiple indoor units is done by the remote controller (M-NET RC) after the electrical power has been turned on.
