Parameter Description Range Default User
Setting
Demand
Source
(advanced
setup)
Selects the source of the demand end-of-interval (EOI) signal.
0 = Internal Timer
1 = Status Input 2
2 = Controller Command
3 = Ethernet Demand Broadcast
Network-demand synch options are available only on units with an
optional Ethernet network installed.
•
If Demand Broadcast Master Select is set to master then a Demand
Source value of 0…2 selects the EOI source that is used to trigger the
demand-synch master broadcast.
•
If Demand Broadcast Master Select is set to slave then a Demand
Source value of 0…3 selects the EOI source.
0…3 0
Demand
Period
Length
(advanced
setup)
Specifies the period for demand calculations. The following include
special cases.
Demand source = 0 (internal time) and demand period length = 0 then
demand metering is disabled
Demand source 0 and demand period length = 0 then projected demand
is disabled
Demand source 0 and demand period length 0 then projected demand is
calculated using the unit’s internal clock
0…
99 min
15 min
Number of
Demand
Periods
(advanced
setup)
Specifies the number of demand periods to average together for demand
measurement. This parameter is used for sliding window demand
calculations. For example, for a 30 minute sliding-window, demand
period length = 2 minutes and number of demand periods = 15.
1…15 1
Forced
Demand Sync
Delay
(advanced
setup)
If demand source 0 and demand period length 0 then this parameter
determines how long the unit waits for an EOI pulse, command, or
broadcast after the expected control pulse has not been received. If the
EOI signal is not received before the waiting period expires, a new
demand period starts and a record is entered in the status log.
Special case: 0 = Wait forever
0…900 s 10
Demand
Broadcast
Master Select
(Ethernet
setup)
0 = Slave, the unit uses its selected demand source to calculate demand.
If demand source = 3 (Ethernet demand broadcast) the unit will listen to
the selected-broadcast port number for a broadcast from the
demand-sync master unit.
1 = Master, the unit broadcasts an EOI broadcast to the selected-UDP
port number when the selected demand source detects an EOI event.
0…1 0
Broadcast
Port Number
(Ethernet
setup)
Specifies the listening or broadcast port for the UDP Ethernet-demand
broadcast message.
