To peel the fi lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening the
screw. On the other hand, an undertightened screw can cause faulty contact, which will
lead to a communication failure.

6. FIELD SETTING

There are 3 methods for address setting by FIELD SETTING as follows.
Set by either of the methods.
Each setting method is described (1) to (3) below.
(1) IU AD, REF AD SW settings.............This section (6.1. Setting the address)
(2) Remote controller settings ............... Refer to the wired or wireless remote controller
(3) Automatic address settings ................. Refer to the outdoor unit manual for detailed

6.1. Setting the address

Manual address setting method
When setting the DIP switch, use an insulated screw driver.
When handling the PCB, static electricity charged in the body may cause malfunction of
the PCB. Follow the cautions below:
• Touch metal part of the indoor and outdoor units for more than 10 seconds to discharge
static electricity charged in the body.
• Do not touch terminals of parts and patterns implemented on the PCB.
(1) Remove the cable clamp and the piping cover.
(2) Remove screws of the heat exchanger, and then remove earthing (grounding) wire.
(3) Remove the shield and the connector cover.
(4) Remove 3 thermistors and 4 connectors.

1 Indoor unit address
Rotary switch (IU AD × 1)...Factory setting "0"
Rotary switch (IU AD × 10)...Factory setting "0"
When connecting multiple indoor units to 1 refrigerant system, set the address at
IU AD SW as shown in the Table A.
2 Refrigerant circuit address
Rotary switch (REF AD × 1)...Factory setting "0"
Rotary switch (REF AD × 10)...Factory setting "0"
In the case of multiple refrigerant systems, set REF AD SW as shown in the Table
A for each refrigerant system.
Set to the same refrigerant circuit address as the outdoor unit.

• If working in an environment where the wireless remote controller can be used, the
addresses can also be set using the remote controller.
• If setting the addresses using the wireless remote controller, set the indoor unit
address and refrigerant circuit address to "00".

Do not set the indoor unit address (IU AD SW) at 64 to 99.
It may result in failure.
3 Remote controller address
Rotary switch (RC AD SW)...Factory setting "0"
When connecting multiple indoor units to 1 standard wired remote controller, set
the address at RC AD SW in sequence from 0.
