Remote Sensor (Optional Parts); Ir Receiver Unit (Optional Parts); Auto Louver Grille (Optional Parts); Field Setting - Fujitsu AIRSTAGE ARXK007GLFH Installation Manual

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. Remote sensor (optional parts)

Connection method
(1) Remove the existing connector and replace it with the remote sensor connector (en-
sure that the correct connector is used).
(2) The original connector should be insulated to ensure that it does not come into
contact with other electrical circuitry.
(3) Use conduit hole when external output cable is used.
*
To protect the cable insulation after opening a knockout hole, remove any burrs from the
edge of the hole.
Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
30 Set the Setting number to "00". (Default)

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)

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.

6.9. Auto louver grille (optional parts)

• For the installation method, please refer to the installation manual of auto louver grille.

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
(2) Remote controller
settings
(3) Automatic address
settings
CNB
01 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
CNB
switches.
01
Indoor unit • Rotary switch (IU AD × 1)...Factory setting "0"
address • 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 • Rotary switch (REF AD × 1)...Factory setting "0"
circuit address • 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.
