* When the forced stop is triggered, indoor unit stops and Start/Stop operation by a
remote controller is restricted.
* When forced stop function is used with forming a remote controller group,
connect the same equipment to each indoor unit within the group.
• Selection method of functions
"Start/Stop" mode or "Emergency stop" mode, "Forced stop" mode can be selected with
function setting of indoor unit.
(2) External output terminals
• When picking up output signals for operating status, abnormal conditions or indoor unit
status.

*2 Provide a DC12 to 24V power supply. Select a power supply capacity
with an ample surplus for the connected load.
*3 The allowable current is 30mA or less. Provide a load resistance such
that the current becomes 30mA or less.
*4 Polarity is [+] for pin 1 and [-] for pins 2-4. Connect correctly.
Do not impress a voltage exceeding 24V across pins 1-2, 1-3, and 1-4.

A twisted pair cable (22AWG) should be used. Maximum length of cable is 492 ft. (150 m).
* Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
(3) Connection methods
• Wire modifi cation
Remove insulation from wire attached to wire kit connector.
Remove insulation from fi eld supplied cable. Use crimp type insulated butt connector to
join fi eld cable and wire kit wire.
Connect the wire with connecting wire with solder.
Important: Be sure to insulate the connection between the wires.

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

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.
Be sure to turn OFF the power before performing the fi eld setting.
• Set it according to the following procedures when setting manually.
It can be set manually if the cover (small) is removed under the condition that the electric
component box cover is attached.
