THE EPM 9450/9650 METER'S TOU CALENDAR CHAPTER 8: TIME-OF-USE FUNCTION
8.2 The EPM 9450/9650 Meter's TOU Calendar
A EPM TOU calendar sets the parameters for TOU data accumulation. You may store up to
twenty calendars in the EPM 9450/9650 meter and an unlimited amount of calendar files
on your computer.
The EPM TOU calendar profile allows you to assign a programmable usage schedule - e.g.,
"Weekday," "Weekend," or "Holiday"- to each day of the calendar year. You may create up
to 16 different TOU schedules.
Each 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 - e.g., "Peak," "Off
Peak," or "Shoulder Peak," to each fifteen-minute interval.
The EPM 9450/9650 meter stores:
• Accumulations on a seasonal basis (up to four seasons per year)
• Accumulations on a monthly basis.
Seasonal and monthly accumulations may span from 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.
If the year ends and there is no new calendar, TOU accumulations stop. The last
accumulation for the year ends on 12:31:23:59:59.
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.
8.3 TOU Prior Season and Month
The EPM 9450/9650 meter stores accumulations for the prior season and the prior month.
When the end of a billing period is reached, the current season or month becomes stored
as the prior. The registers are then cleared and accumulations resume, using the next set
of TOU schedules and register assignments from the stored calendar.
Prior and current accumulations to date are always available.
