8.3: TOU Prior Season and Month 8.3: TOU Prior Season and Month
n
The Nexus Monitor 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.
n
Prior and current accumulations to date are always available.
8.4: Updating, Retrieving and Replacing TOU Calendars 8.4: Updating, Retrieving and Replacing TOU Calendars
n
Nexus Communicator software retrieves TOU calendars from the Nexus Monitor or from the
computer’s hard drive for review and edit.
n
Up to a maximum of twenty yearly calendars can be stored in the Nexus Monitor at any given time.
You may retrieve them one at a time; a new calendar can be stored while a current calendar is in use.
n
Accumulations do not stop during calendar updates. If a calendar is replaced while in use, the
accumulations for the current period will continue until the set end date. At that point, the current
time will become the new start time and the settings of the new calendar will be used.
n
Reset the current accumulations, if you replace a calendar in use. A reset clears only the current
accumulation registers. This causes the current accumulations to use the present date as the start and
accumulate to the next new end date, which will be taken from the new calendar. Once stored, prior
accumulations are always available and can not be reset. See the
Nexus Communicator User Manual
for how to reset TOU accumulations.
n
At the end of a defined period, current accumulations are stored, the registers are cleared and
accumulations for the next period begin. When the year boundary is crossed, the second calendar, if
present, is used. To retain continuity, you have up to one year to replace the old calendar with one
for the following year.

n
To use Daylight Savings Time, you must enable it in the Nexus Monitor’s Device Profile and enter
the associated dates or use the default dates of the first Sunday in April at 1:59:59 (to 3:00:00) and
the last Sunday in October at 1:59:59 (to 1:00:00). See the
Nexus Communicator User Manual . Or,
you can use Auto DST , which sets Daylight Savings Time automatically (for the United States
ONLY).
n
You must also select a fixed or sliding window average method for the accumulation values.
