Not doing so may cause an electric shock.
When two indoor units are installed side by side, the
commands from the wireless controller may be received
by both indoor units. The function, “Identifying of Indoor
Units Installed Side by Side” enables operation of the
individual unit correctly without interfering with the
other unit’s operation. As shown in the figure at the
right, the indoor units of A and B are set side by side. In
this instance, unit B is set as “Identifying Indoor Units
Installed Side by Side”.

Up to 16 indoor units can be simultaneously
controlled using one wireless controller.
When multiple indoor units are installed in a large
room, all the indoor units can be controlled to start/
stop with only one wireless controller.
NOTE:
Do not apply a simultaneous operation for indoor
units installed separately in different rooms.
Some units may be left without turning OFF the
power supply.
[ Installation of IR Receiver Kit ]
In an instance of simultaneous operation of multiple (up to 16 ) indoor units by the wireless controller, install
the IR receiver kit only to the unit to be operated. Other units should be standard units without the IR
receiver kit. If multiple IR receiver kits are required to be installed, two IR receiver kits are the maximum.
