Demand Response and Indoor Unit Operation
This product is designed to be compatible with Air Conditioning Demand Response program.
To utilize the function, Demand Response (DR) adapter kit that interconnects your air conditioner and Demand Response Enabling Device (DRED) needs to be
installed in your air conditioning system, and you need a separate arrangement with your electricity supplier.
WARNING
This unit contains no user-serviceable parts. Always consult authorized service personnel for repairing, installation, and relocation of this product.
Improper installation or handling will cause leakage, electric shock, or fi re.
When your electricity supplier activates one of the following 3 DR modes, the air conditioner switches over to the appropriate operation, and the OPERATION
indicator (green) on the indoor unit blinks to inform you the unit has entered the DR mode.
OPERATION indicator
(indoor unit)
Blinking pattern and the intervals are as follows
The indicator will keep blinking until the unit fi nishes the function.
Notes:
• Shape, number, and the arrangement of the indicators are unit-dependent.
• Some indoor units may not have the indicators unless the optional control panel or IR receiver kit has been
installed.
● AUTO/COOL/HEAT/DRY/FAN operations
● 10˚C HEAT operation
ON (4 seconds) OFF (0.5 seconds)
OFF (0.5 seconds) ON (0.5 seconds)
OFF (4 seconds) ON (0.5 seconds)
ON (0.5 seconds) OFF (0.5 seconds)
DR mode Description of operation in this mode
DR mode 1
Compressor off.
DR mode 2
The air conditioner continues to cool or heat during the Demand Response event, but the electrical energy consumed by the air conditioner
in a half hour period is not more than 50% of the total electrical energy that would be consumed if operating at the rated capacity in a half
hour period.
DR mode 3
The air conditioner continues to cool or heat during the Demand Response event, but the electrical energy consumed by the air conditioner
in a half hour period is not more than 75% of the total electrical energy that would be consumed if operating at the rated capacity in a half
hour period.
When the unit enters the DR mode, it performs moderate operation so the cooling or heating effect may be reduced. You cannot override this function by changing
the temperature setting using the remote controller or other actions unless the unit fi nishes the function.
Note: Stopping the operation of the air conditioner by using the remote controller or by OFF timer are valid in DR mode.
When the unit fi nishes the function, it will perform the operation that was previously performed before entering the DR mode.
When this air conditioner is connected to a DRED, and you have operational issues, contact your electricity supplier fi rst to check whether they are activating any
of the DR mode described above.
If the air conditioner is under demand controlling, consult on the issues with your electricity supplier.
If they are not demand controlling the air conditioner, refer to your warranty card for the contact details of Fujitsu General (AUST.) PTY LIMITED or visit our website:

Preparation for installation
Parts list for demand control option PCB kit (optional parts)
Items to be prepared:
• Demand control option PCB kit: optional parts
• Signal transmission cable (fi eld supply) : for demand control signal
transmission
Double insulated (cable size: 0.5–1.5 mm
2
)
NOTE: Use cable conformed to AS/NZS 5000.2.
For outdoor unit
How to connect
(1) Remove the service panel of the
outdoor unit.
(2) Remove the INV cover of the main
unit board.
(3) Attach spacers (in four places) to the
demand control option PCB.

(9) Fix the signal transmission
cable with the cable tie
(with clip).Then cut off the
redundant end of the cable
tie.
Do not route the signal
transmission cable
overlapping with the power
supply cable. Then wire the
cable to the outside of the
outdoor unit.
(7)
Connect the signal transmission cable (fi eld-supplied)
to the demand control signal terminal block.
NOTE: Confirm that each wires of the signal
transmission cable are firmly connected
to corresponding terminal of the terminal
block.

(4) Fix the demand control option PCB with
four spacers attached to the holes on the
bracket so that the demand control signal
terminal block comes underneath.
(6) Connect the demand control option PCB
and CN14 on the control board by using the
connector cable (Large Core).
Attach the Insulation to the EMI core.
Put the Connector cable and the earth
(ground) wire into the notch.
NOTE: Confirm that the connector cable
is fi rmly connected to the demand
control option PCB and the control
board.
CAUTION
Do not directly press or apply any pressure to the demand control option PCB.
Application of pressure may cause damage or fault of the board.
(12)After you complete the wiring, reinstall the
protective cover and the service panel fi rmly.
• When testing the operation of the demand control modes, please ensure the
air conditioner and optional PCB has been installed in accordance with the
provided installation manuals.
• Enquiries when testing the operation of the demand control option PCB,
Consult Fujitsu General Customer Service and your energy provider if you
have any operational issues or errors are caused.
Signal transmission cable
Attach the one-touch bush to the knockout hole.
CAUTION
Route the signal transmission cable away from the power supply cable.
Adjacent wiring of those cables may lead the product malfunctions caused by
generated noise.
Cable tie with clip
WARNING
• Do not turn ON the power until all work has been completed. Turning ON
the power before the work is completed can cause serious accidents such
as electric shock or fire.
• Ensure that any electrical installation is completed by a qualifi ed person.
• Ensure the electrical installation is installed in accordance with AS/NZS
3000.
