(A) When the Peak Cut method [Demand-Input PLC] is selected
(1) In the [IP Address] field, enter the IP address of the Demand-Input PLC.
(2) When using the Demand-Input PLC for the first time, click [Initialize] to initialize its internal memory.
Note: Do not initialize the Demand-Input PLC after the operation has begun, for it will clear all operation data.
(3) In the [Controlled AE] field, enter the IP addresses of the AE-200/AE-50/EW-50 units to which the demand
level signal is sent. Up to 10 IP addresses can be registered.
(4) In the [Temperature difference between set point and inlet] section, a temperature differential can be set to
between 3 and 9 as necessary. The Peak Cut control setting that corresponds to the control level 0 will be
disregarded for the indoor unit groups in which the temperature difference between the set temperature and
the room temperature is greater than the specified temperature differential.
Note: The Peak Cut control setting that corresponds to the control levels 1 to 4 will be effective regardless of the
temperature differential setting.
(B) When the Peak Cut method [Electric Amount Count PLC] is selected
(1) In the [IP address] field, enter the IP address of the Electric Amount Count PLC.
(2) When using the Electric Amount Count PLC for the first time, click [Initialize] to initialize the internal memory.
Note: Do not initialize the Electric Amount Count PLC after the operation has begun, for it will clear all operation data.
(3) In the [DI Board] field, select the DI board number to which the watt-hour meter is connected, and the
terminal number. If the watt-hour meter is connected to terminal 2 on a DI board 1, select 1-2.
Note: Select a DI board number 1 or 2, and select a terminal number/code between 0 and F.
(4) In the [Pulse Unit] field, enter the pulse value that the watt-hour meter outputs. Set the pulse value according
to the watt-hour meter to be used.
Important: Check the watt-hour meter readings several times on the hour and the half-hour. Then, be sure to check
that the increase in the watt-hour meter reading for each 30-minute period and the average electric power
consumption in the same period that the Peak Cut function is used are the same amount.
(5) In the [Control levels] section, the range of the electric power must be set for each control level. For control
level 4, enter the value that is 10% to 15% below the maximum power demand (average electric energy that
cannot be exceeded in any 30-minute period). For control levels 3 to 0, enter the value that is decreased
by about 10% from the set value of the previous control level. (The screenshot above shows the setting
example of the maximum demand of 200 kW.)
Note: The optimum setting depends on the system configuration of the electric equipment and on the indoor environment in
each building. Determine the appropriate values accordingly.
