8.1:
Introduction
QA Time-of-Use (TOU) usage structure takes into account the quantity of energy used and the time at
which it was consumed. The Nexus 1250/1252 TOU function, available with the Communicator
EXT software, is designed to accommodate a variety of programmable rate structures. Nexus TOU
accumulates data based on the time-scheme programmed into the Nexus Monitor.
QSee the Communicator EXT User Manual for details on programming the Nexus 1250/1252 20 Year
TOU calendar and retrieving TOU data.
8.2:
The Nexus TOU Calendar
QA Nexus TOU calendar sets the parameters for TOU data accumulation. You may store up to twenty
calendars in the Nexus 1250/1252 Monitor and an unlimited amount of calendar files on your
computer.
QThe Nexus TOU calendar profile allows you to assign a programmable usage schedule—eg,
“Weekday,” “Weekend,” “Holiday”—to each day of the calendar year. You may create up to 16
different TOU schedules.
QEach TOU schedule divides the 24-hour day into fifteen-minute intervals from 00:00:00 to 23:59:59.
You may apply one of eight different programmable registers—eg “Peak,” “Off Peak,” “Shoulder
Peak”— to each fifteen-minute interval.
QThe Nexus 1250/1252 Monitor stores:
•accumulations on a seasonal basis, up to four seasons per year;
•accumulations on a monthly basis.
QSeasonal and monthly accumulations may span one year into the next. Each season and month is
defined by a programmable start/billing date, which is also the end-date of the prior season or month.
•A season ends at midnight of the day before the start of the next season.
•A month ends at midnight of the month’s billing day.
QIf the year ends and there is no new calendar, TOU accumulations will stop. If a calendar is present
for the following year, TOU accumulations continue until the next monthly bill date or next
start-of-season is reached. Accumulation can span into the following year.
QIf no following year is present, the last accumulation for the year will end on 12:31:23:59:59.
