Address Switches

• Heat pump models
If you are installing more than 1 indoor unit (up to 3) in the same room, it is necessary for you to assign each unit its own address
so they each can be operated by their remote controller.
Up to 3 indoor units can be controlled separately through the address switches. The operating control has the reception address
switch and the remote controller has transmission address switch. This function is utilised by matching the transmission and
reception address switches.
EX) 3 indoor units in 1 room

* Reception may be impossible if the remote controller is too far away. In this case, either use individual control or group control.
• Cooling only models
The address switch setting function is not available on the remote controller. Be sure to set the ADDRESS switch on the operation
controller to 1 (Fig. 4-8).

Regarding the test run, please refer to the Installation
Instructions provided with the outdoor unit.
NOTE
• In case of 4-way air discharge type, test run operations is
not possible without the ceiling panel installation.

unit will flash.
• During the test run, the air conditioner runs continuously
and the thermostat does not control the system.
• To protect the air conditioner from overloading, the outdoor
unit will not start running for 3 minutes after power is applied
or the air conditioner is turned off and then back on.
• When the air conditioner fails to start the test run, 1 or more
of the 3 alarm indicator lamps on the indoor unit will flash
(See next section - Heat pump models only).
