Shed Level:
Restore Level:
When the [analog] input associated with this program rises to the
shed level, the system will start turning off the binary globals which
are listed as “items to be shed.” When the [analog] input associated
with this program falls to the restore level, the system will start
turning the binary globals listed as “items to be shed” back on.
Shed/Restore Screen
Shed/Restore Program #:
Specifi es the number of the program you are currently editing. The
WCC III system has 10 shed/restore programs.
Shed/Restore based on input:
Specifi es the [analog] point address that acts as the input signal
source for this shed/restore program. For example, if you are
monitoring the kW demand of a building, and the kW meter is
connected to analog input #1 of satellite controller #10, you would
input 10A1. You may also use global analog values for this input.
and schedule:
Specifi es the [binary] point address that provides the schedule
control of the shed/restore program. When this address is zero (or
OFF), the OFF schedule mode is selected. When this address is one
(or ON), the ON schedule mode is selected.
This fi eld must have a valid WCC III binary structured value that
must be used as a binary input value for this screen to operate
correctly. Satellite Binary Input (XXXLWW), Satellite Control
“C” output (XXXkYc), Satellite Control “H” output (XXXkYh),
Satellite Binary Output (XXXOWW), Global Binary (GBZZZ),
where WW equals 1 to 16, XXX equals 1 to 239, Y equals 1 to 8,
and ZZZ equals 1 to 512.
Shed/Restore rate:
Specifi es the time interval the system uses to turn the items on
or off. For example, if you have a shed/restore rate of 1 minute
per item, and the value of the analog input rises above the shed
level, the system will shut off the fi rst binary global (GB21 on the
example screen) and wait one minute. If the analog input value is
still above the shed level, the next global will be turned off (GB22
on the example screen). This process will continue (through GB36)
until the value of the analog input is below the shed level. After the
value of the analog input falls below the shed level, the system
will not turn any binary globals back on until the analog value falls
below the restore level. At this point, the system will start bringing
the binary globals back on at the time interval specifi ed by the
shed/restore rate in reverse order starting with the last binary global
that was shed.
