For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units.
Confirm the system type.
• Pair type:

dard system).
• Simultaneous operation system:

1 remote controller controls up to 16 indoor
units
(All indoor units operate according to the
remote controller).

NOTE
1. All transmission wiring except for the remote controller wires
is polarized and must match the terminal symbol.
2. When BRC1B517 is connected, use shield wire in transmis-
sion wiring. Ground the shield of the shield wire, at the
grounding screw of the remote controller cord grounding ter-
minal inside the control box.
3. In case of group control, perform the remote controller wir-
ing to the master unit when connecting to the simultaneous
operation system. (wiring to the slave unit is unnecessary)

troller that suits the indoor unit which has the most functions
