[9] Example System with an MA and an ME Remote Controller

System with a Connection of System Controller to Centralized Control Transmission Line
-1- System with a Connection of System Controller to Centralized Control Transmission Line
(1) Sample control wiring
(2) Cautions
1) Be sure to connect a system controller.
2) ME remote controller and MA remote controller cannot both be con-
nected to the same group of indoor units.
3) Assign to the indoor units connected to the MA remote controller ad-
dresses that are smaller than those of the indoor units that are con-
nected to the ME remote controller.
4) No more than 2 ME remote controllers can be connected to a group
of indoor units.
5) No more than 2 MA remote controllers can be connected to a group
of indoor units.
When a PAR-CT01MA series, PAR-4"x"MA series, or PAR-3"x"MA
series ("X" represents 0 or later) is connected to a group, no other
MA remote controllers can be connected to the same group.
6) Do not connect the terminal blocks (TB5) on the indoor units that are
connected to different outdoor units with each other.
7) Replace the power jumper connector of the control board from CN41
to CN40 on only one of the outdoor units (not required if power to the
transmission line for centralized control is supplied from a controller
with a power supply function, such as GB-50ADA).
8) Provide an electrical path to ground for the S terminal on the terminal
block for centralized control on only one of the outdoor units.

*1 When only the LM adapter is connected, leave SW5-1 to OFF (as it is).
*2 LM adapters require the power supply capacity of single-phase AC 220 - 240V.
9) When the number of the connected indoor units is as shown in the
right table, one or more transmission boosters (sold separately) are
required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that are
listed in the specifications for each outdoor unit.)
Number of transmission booster (sold separately) required
1 unit
13 - 32 units
The above table shows the number of transmission
boosters that is required by the system with four HBC
controllers. For each HBC controller added or subtract-
ed, subtract or add two indoor units.
Refer to the DATABOOK for further information about
how many booster units are required for a given system.
10) When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper
connector on CN41 as it is (factory setting).
