- DR mode 1: Compressor off.
- DR mode 2: The air conditioner continues to cool 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 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.
What happens when the unit enters DR mode?
When the unit enters DR mode, it performs moderate operation, so the cooling effect may be reduced. You cannot override this function by changing the temperature setting using the remote controller or other actions unless the unit finishes the function.
Can I stop the operation of the air conditioner during DR mode?
Yes, stopping the operation of the air conditioner by using the remote controller or by OFF timer are valid in DR mode.

Powerful operation is performed within the operable range of the DR mode.
What happens when the unit finishes DR mode?
When the unit finishes the function, it will perform the operation that was previously performed before entering the DR mode.
What should I do if I have operational issues during DR mode?
If you have operational issues, contact your electricity supplier first to check whether they are activating any of the DR modes described above. If the air conditioner is under demand controlling, consult 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.
