6.7. Remote sensor (optional parts)
Connection method
•
Remove the existing connector and replace it with the remote sensor connector (ensure
that the correct connector is used).
•
The original connector should be insulated to ensure that it does not come into contact
with other electrical circuitry.
•
Use conduit hole when external output cable is used.
Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
•
Function Number “30”:
Set the Setting Number to “00”. (Default)
•
Function Number “31”:
Set the Setting Number to “02”.
* Refer to “7.6. Function setting” for details about Function Number and Setting Number
6.8. IR receiver unit (optional parts)
•
For the installation method, please refer to the INSTALLATION MANUAL of IR receiver
unit.
Connection method
•
Use 9 pins for receiver unit cable.
•
At first, connect the receiver unit cable to the controller PCB.
•
Attach the core that comes between controller PCB and the clamp.
•
Use conduit hole when external output cable is used.
6.9. Auto louver grille kit (optional parts)
•
For the installation method, please refer to the INSTALLATION MANUAL of Auto louver
grille kit.
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
information. (Set IU AD, REF AD SW to 0)
CAUTION
Be sure to turn OFF the power before performing the field setting.
Do not operate any switches other than prescribed, as it can cause the unit to operate
improperly or malfunction.
Use an insulated screwdriver to set the DIP switches.
7.1. Setting the address
Manual address setting method
The indoor unit address and the refrigerant circuit
address can also be set up through the wireless
remote controller.

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.
