6.7. Remote sensor (Optional parts)

• For the installation method, please refer to the INSTALLATION MANUAL of remote
sensor.
Connection methods
• 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 "7.4. Function setting" for details about Function
Number and Setting Number.

6.8. 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
(3) Automatic address settings ............. Refer to the outdoor unit manual for detailed
CNB
Be sure to turn OFF the power before performing the fi eld setting.

7.1. Setting the address

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.
Use an insulated screwdriver to set the DIP switches.
