OPERATION indicator (green) on the indoor unit blinks to inform you the unit has entered the DR mode.
Blinking pattern and the intervals are as follows:
● 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)

Instructions for Users
Before using this product, read these instructions thoroughly
and keep this manual for future reference.
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.
OPERATION indicator
(indoor unit)
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.
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.
If the timer operation is interfered by an interruption of power supply such as a blackout and the power supply is resumed, no indication of the DR mode is performed.
During the DR mode, no indication of "fi lter sign" is performed.
Powerful operation is performed within the operable range of the 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
