[3] An Example of a System to which an MA Remote Controller is connected

1. System with one outdoor unit (Heat source unit) (automatic address setup for both indoor and outdoor units)
(1) Sample control wiring

(2) Cautions
1) ME remote controller and MA remote controller cannot
both be connected to the same group of indoor units.
2) No more than 2 MA remote controllers can be connected
to a group of indoor units.
3) When the number of the connected indoor units is as
shown in the table below, 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.)

put(CN32, CN51, CN41) is used for a group operation of
indoor units.
5) No more than 2 HBC controllers can be connected.
Sub-HBC controller cannot be connected.
