(4) Scheduled operation
Configure the schedule settings using a remote controller (PAR-W31MAA) or a system controller (AE-200).
(5) Peak-demand control operation
Peak-demand control is a function used to control the power consumptions of the units during peak-demand hours.
The number of units in operation and the compressor's maximum operating frequency will be controlled
according to the peak-demand control signal.
Individual system control Multiple system control
Individual unit control
Maximum frequency = Maximum capacity under peak-
demand control
Depending on the peak-demand control setting that is
made on the main unit, the number of units in operation
and the maximum operating frequency of the units in
operation will be adjusted.
Setting procedures
Set the maximum capacity setting on the circuit board.
Step 0
Set the ON/OFF
switch (SWS1) to
OFF.
Set SWS1 to OFF from the remote controller or with the local switch.
Settings cannot be changed unless the ON/OFF setting is set to OFF. *
Step 1
Set the dip switches
SW2 and SW3.
Set the dip switches on the circuit board as follows before making the settings for the items
described in this section.
Step 2
Select the desired
item with the push
switch SWP3.
Press the push switch SWP3 to select item code 2.
Press the push switches SWP1 or SWP2 to change the value of the selected item.
The value will keep blinking while it is being changed.
Step 3
Press the push
switches SWP1 ()
or SWP2 () to
increase or
decrease the value.
Step 4
Press the push
switch SWP3 to
save the change.
Press SWP3 once within one minute of changing the setting with SWP1 or SWP2 to save the
setting.
Once the new setting is saved, the display will stop blinking and stay lit. The display will, then,
return to the item code display mode.
If SWP3 is not pressed within one minute, the change will not be saved and the display will
return to the item code display mode.
(*) If the peak-demand control contact is ON, units will operate at the maximum capacity that
was set in the steps above.
*
The maximum frequency may be restricted depending on the inputs of maximum demand capacity and
maximum low-noise capacity. Refer to page 73 for details.
