● OPERATING INSTRUCTIONS ●
Demand response
This unit has demand response capability which is compliant with AS/NZS 4755.3.1.
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 2
The air conditioner continues to perform cooling or heating
operation during the demand response event, but the elec
-
trical 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.
DRM 3
The air conditioner continues to perform cooling or heating
operation during the demand response event, but the elec
-
trical 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.
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.

EMAND RESPONSE AND INDOOR UNIT OPERATION
Operation indicator lamp
When the remote controller cannot be used...
Emergency operation can be activated by pressing the emergency operation
switch (E.O.SW) on the indoor unit.
Each time the E.O.SW is pressed, the operation changes in
the following order:
If a power failure occurs or the main power is turned off during operation, “Auto
restart function” automatically starts operation in the same mode as the one set
with the remote controller just before the shutoff of the main power. When timer is
set, timer setting is cancelled and the unit starts operation when power is resumed.
If you do not want to use this function, please consult the service repre-
sentative because the setting of the unit needs to be changed.
