5. Demand Control Function
At peak demand, electrical consumption is reduced by the external demand control signal.
Only input terminal 1 is now available from the external demand signal.
The operation mode of a selected group will be changed by the demand signal as follows:
Demand Signal ON (*1) Demand Signal OFF (*2)
Stop (2)
(See list below)
Indoor Unit
Operation Stop with RCS Operation Prohibited
Mode
The operating condition returns
to previous status. (3)
Run Mode Shift
(2) (4)
Cooling or Dry Operation
Fan Operation with RCS Operation Prohibited
Mode
Heat Operation
Operation Stop with RCS Operation Prohibited
Mode
Outdoor Unit
Capacity
Control
(5) (6) (7)
Control the value of outdoor unit capacity in the
setting value.
(Setting value: 100/90/80/70/60/50/40/0%).
Cancel the capacity control.
1. Do not set “STOP” or “Run Mode Shift” when used simultaneously with another central controller.
When setting outdoor unit capacity control, set one of the central controllers but do not set the others.
2. Setting is only possible for Stop or Run Mode Shift. It is not possible to set multiple contacts.
3. The target group: “Demand Function” is controlled, starting from a small, numbered group at intervals of
15 seconds.
4. It will stop, regardless of the operating mode as in Auto or when the “Operating Mode Fixed” in the
optional function setting is enabled.
5. Outdoor unit capacity control can be set to multiple contacts.
When there is a signal input in multiple contacts, the control with the highest contact will be done in the
order of priority as follows: (Input 1 > Input 2 > Input 3 > Input 4).
6. The control target is only the outdoor unit corresponding to the outdoor unit capacity control.
Because the outdoor unit like compliant/non-compliant or settings available to capacity value may be
different, contact your distributor for detailed information.
7. It is possible to control by way of a schedule without having to use demand control.
Ŷ External Output Function
1. All Run Output
External output for indoor unit operation signal in the target group:
The operational output signal displays, even if only one indoor unit in the target group is in operation.
2. External Output Alarm
External output alarm signal for indoor unit in the target group
The alarm signal outputs even if one indoor unit abnormality occurs in the target group.
