(3) Touch the [DI Board] or [Pulse Unit] button to open the window to 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.
The average electric power for the period that the Peak Cut function is used can be checked on the [Peakcut]
screen.
(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.
(6) 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.
