How to wire the simplified remote controller
This multiple remote controller system controls 1 to 8
indoor units with 2 simplified remote controllers.
1. One of the 2 simplified remote controllers should be set as
main controller.
2. For the rest, see the “Remote controller setting mode”
section and set up Sub.
1. Following is a wiring diagram for controlling 1 indoor unit by
2 simplified remote controllers.
2. Performing group control of the multiple indoor units with
2 simplified remote controllers.
3. The main and the sub simplified remote controllers can be
installed at any indoor unit for operations.

Set-up procedure
Guidelines for using 2 simplified remote controllers
1. Do not twist the simplified remote controller wiring
with the power wiring or run it in the same metal
conduit, because this may cause malfunction.
Make sure to connect the wires correctly or the unit
may be damaged. (See Fig. 3-70)
2. Install the simplified remote controller away from
sources of electrical noise.
3. Install a noise filter or take other appropriate action
if electrical noise affects the power supply circuit of
the unit.
• Use an electric junction box (supplied locally)
(See Fig. 3-64) for flush mounting of the simplified
remote controller
