(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.
(C) When the Peak Cut method [PI Controller] is selected
(1) In the [Watthour meter] field, select the watt-hour meter used for the Peak Cut function or the PI controller to
which the watt-hour meter is connected.
Note: Only the watt-hour meters that have been registered on the Measurement screen are selectable. Refer to section
7-2-3 “Measurement” for how to register metering devices.
Note: When a built-in Pulse Input (PI) is used, [“Meter” + 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,” [Meter3 For Peak Cut function] will appear.)
When a PI controller (PAC-YG60MCA) is used, [“Address” + 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, [Address10-2] will
appear.)
(2) 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.
(3) 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.
Note: When a PI controller is only connected to AE-200, and when AE-50/EW-50 monitors AE-200, select “Remote AE” for
AE-50/EW-50.
