(1) Touch the [Watthour meter] button to open the window to select the PI controller to which the watt-hour meter
used for the Peak Cut function is connected.
Note: Only the watt-hour meters that have been registered on the [Measurement] screen are selectable. (Refer to section 5-2-
2 “Measurement” for how to register metering devices.)
Note: When a built-in Pulse Input (PI) is used, [Channel No. + (space) + Metering device name] will appear. (For example, if
the watt-hour meter used for the Peak Cut function is connected to channel 3 of CN7 of AE-200 and the metering device
name is “For Peak Cut function,” [3 For Peak Cut function] will appear.)
When a PI controller (PAC-YG60MCA) is used, [PI controller address + “-” + Channel No. + (space) + Metering device
name] will appear. (For example, if the watt-hour meter used for the Peak Cut function is connected to channel 2 of a PI
controller (address 10) and the metering device name is not registered, [10-2] will appear.)
Note: To deselect the selection, select [-- --].
(2) 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.
(3) 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.
Note: Other than the AE-200/AE-50/EW-50 units that use a built-in Pulse Input (PI) or a PI controller (PAC-YG60MCA), up
to three more AE-200/AE-50/EW-50 units can be controlled. Refer to (D) “When the Peak Cut method [Remote AE] is
selected” below for details.
