Safety Precautions

Demand Response and Indoor Unit Operation

Before using this product, read these instructions thoroughly and keep this manual for future reference.

To prevent personal injury, injury to others, or property damage, read this manual carefully, and be sure to comply each safety notice. Incorrect operation or installation due to failure to follow the instructions may cause harm or damage, the seriousness of which is classified as follows:

This product is designed to be compatible with Air Conditioning Demand Response program.

Note:

DR mode Description of operation in this modeDR mode 1 Compressor off.

DR mode 2The 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 3The 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 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 it has been entered to the DR mode.

When the unit goes into a DR mode, it performs moderate operation though the cooling or heating effect may be reduced. You cannot override this function with changing the temperature setting by using the remote controller or other actions unless the unit finishes the function.

When the unit finishes the function, it will perform the operation that was previously performed before entering the DR mode.

DEMAND RESPONSE-COMPATIBLE AIR CONDITIONER

INSTRUCTION MANUAL

When this air conditioner is connected to a DRED, and you have operational issues, contact your electricity supplier first 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 : www.fujitsugeneral.com.au

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.

OPERATION indicator (indoor unit)

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.

Blinking pattern and the interval are as follows:

The indicator will keep blinking until the unit finishes the function.

OFF (0.5 seconds)ON (4 seconds)

ON (0.5 seconds)OFF (0.5 seconds)
