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. Refer to "6.3. Function setting" for details about Function number and Setting
number.
• Function Number "30": Set the Setting Number to "00". (Default)
• Function Number "31": Set the Setting Number to "02".
NOTE:
For optional parts not listed here, refer to the installation manuals included with each
optional part.
6. FIELD SETTING

the methods. Each setting method is described in below (1) to (3).
(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 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)
