6.6.2. External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m.
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• Output voltage: Hi DC 12 V ±2 V, Lo 0 V.
• Permissible current: 50 mA

6.7. IR receiver unit (optional parts)
Connection method
• For the installation method, please refer to the installation manual of IR receiver unit.
(1) Use 9 pins for receiver unit cable.
(2) At first, connect the receiver unit cable to the controller PCB.
(3) Attach the core that comes between controller PCB and the clamp.
(4) Use conduit hole when external output cable is used.
7. 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 (“7.1. Setting the address”)
(2) Remote controller
settings
Refer to the wired or wireless remote controller manual for
detailed setting information. (Set IU AD, REF AD SW to 0)
(3) Automatic address
settings
Refer to the outdoor unit manual for detailed setting informa
-
tion. (Set IU AD, REF AD SW to 0)
CAUTION
Be sure to turn OFF the power before performing the field setting.
7.1. Setting the address
7.1.1. Manual address setting method
• If the receiver unit is attached, the indoor unit address and the refrigerant circuit address
can also be set up through the wireless remote controller.
CAUTION
Use an insulated
screwdriver to set the DIP
switches.

• 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.
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 environ
-
ment 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”.
(For information on set
-
ting using the wireless
remote controller.)
*
Do not set the indoor
unit address (IU AD
SW) at 64 to 99.
It may result in failure.
