9. Installation and operation manual for demand response (DRED)
9.4. Demand response mode
This unit has demand response capability which is compliant with AS/NZS 4755.3.1: 2012.
To activate this function, you need to make a contract with remote agents such as electric supply company, then this unit should be connected to Demand response enabling
devise (DRED). For further information, consult your dealer.
Demand response represents the automated alteration of an electrical product's normal mode of operation in response to an initiating signal originating from or defined
by a remote agent.
This unit supports 3 Demand Response Modes (DRMs).
DRM
Compressor off
DRM 1
The air conditioner does not perform cooling or heating operation during the demand response event.
The air conditioner continues to perform cooling or heating operation during the demand response event, but the electrical energy consumed by the
DRM 2 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.
The air conditioner continues to perform cooling or heating operation during the demand response event, but the electrical energy consumed by the
DRM 3 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.
Note:
• DRM is automatically activated or released according to the signals from DRED.
DRM cannot be invalidated or changed manually.
• You might feel this unit does not sufficiently perform cooling or heating operation during DRM.
• Operation settings can be changed as usual with the remote controller during DRM.
However, you might not feel cool or warm enough as DRM is prioritized.
• When this unit receives the DRM1 signal, the response time until the DRM1 mode is activated is within 60 sec.
However, if the maintenance and safety modes are activated, those modes have priority.
• The terminal block for the DRED satisfies the ELV requirements.
