DEMAND RESPONSE (DR) and indoor unit operation
This product is designed to be compatible with
Air Conditioning Demand Response program.
To utilize the function, Demand Response 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.
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.
Blinking pattern
The indicator will keep blinking until the unit finishes the function.
Note: Shape, number, and the arrangement of the indicators are unit-dependent.
DR mode
DR mode 1
DR mode 2
DR mode 3
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 control or other actions unless the unit finishes
the function.
Note :
When the unit finishes 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 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
