Address setting

On this unit, it is required to set the addresses of the indoor units before starting air conditioning.
Set the addresses following the steps below.
CAUTION
• Be sure to complete the electric wiring before setting the addresses.
• If you turn on the outdoor unit before turning on the indoor units, the CODE No. [E19] is indicated on the 7-
segment display on the interface P.C. board of the outdoor unit until the indoor units are turned on. This is not a

• Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)

• The addresses can be set manually.
Automatic addressing: setting addresses using SW15 on the interface P.C. board on the header outdoor unit
Manual addressing: setting addresses on the wired remote controller.
* When setting an address manually, the wired remote controller must temporarily be
paired with an indoor unit one-to-one. (when the system is organized for group
operation and no Remote controller)

If you set addresses on an outdoor unit, operate the
unit through the access door shown on the illustration
