Example of a group operation system with multiple outdoor units (Shielding wires and address setting are necessary.)
<Examples of transmission cable wiring>
[Fig. 11.3.1] M-NET Remote Controller
<A> Change the jumper connector
from CN41 to CN40 *1
<B> SW5-1: ON *2
( ) Address
<C> Keep the jumper connector
on CN41
<B> SW5-1: ON *2
A : Group 1
B : Group 3
C : Group 5
D : Shielded wire
E : Sub remote
controller
( ) Address
*1: When the power supply unit is not connected to the transmission line for centralized control, disconnect the male power supply connector (CN41) from ONE
outdoor unit in the system and connect it to CN40 (except TKMU model). When the System controller is connected to TB7 side and TKMU outdoor unit model is
used, connect a PAC-SC51KUA to TB7 side. If a PAC-SC51KUA cannot be used, connect the System controller to TB3 side. Up to three System controllers can
be connected to TB3 side.
*2: If a system controller is used, set SW5-1 on all of the outdoor units to ON.
[Fig. 11.3.2] MA Remote Controller
<A> Change the jumper connector
from CN41 to CN40 *1
<B> SW5-1: ON *2
<C> Keep the jumper connector
on CN41
<B> SW5-1: ON *2
A : Group 1
B : Group 3
C : Group 5
D : Shielded wire
E : Sub remote
controller
( ) Address
*1: When the power supply unit is not connected to the transmission line for centralized control, disconnect the male power supply connector (CN41) from ONE
outdoor unit in the system and connect it to CN40 (except TKMU model). When the System controller is connected to TB7 side and TKMU outdoor unit model is
used, connect a PAC-SC51KUA to TB7 side. If a PAC-SC51KUA cannot be used, connect the System controller to TB3 side. Up to three System controllers can
be connected to TB3 side.
*2: If a system controller is used, set SW5-1 on all of the outdoor units to ON.
*3 : When a PAR-30MAAU is connected to a group, no other MA remote controllers can be connected to the same group.
