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
malfunction.
It may take up to ten minutes (normally about five minutes) to address one refrigerant line automatically.
Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)
Running the unit is not required for address setting.
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)
REQUIREMENT
High voltage parts exist in the electrical control box.
If you set addresses on an outdoor unit, operate the
unit through the access door shown on the illustration
on the right to avoid electric shock. Do not remove the
cover of electrical control box.
* After finishing operations, close the access door cover
and fix it with the screw.
