8.3: TOU Prior Season and Month
The Nexus 1250/1252 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.
Prior and current accumulations to date are always available.
8.4: Updating, Retrieving and Replacing TOU Calendars
Communicator EXT software retrieves TOU calendars from the Nexus 1250/1252 Monitor or from the computer’s hard drive for review and edit.
Up to a maximum of twenty yearly calendars can be stored in the Nexus 1250/1252 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.
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.
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.
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.
8.5: Daylight Savings and Demand
To use Daylight Savings Time, you must enable it in the Nexus Monitor’s Device Profile, Time Settings. Click Auto DST, which sets Daylight Savings Time automatically (for the United States ONLY). You can also select User Defined and enter the desired dates for Daylight Savings Time. See the Communicator EXT User Manual for details.
To set Demand Intervals, from the Device Profile select Demand Integration and set the desired intervals.
To set Cumulative Demand Type, from the Device Profile click Cold Load Pickup and select Block or Rolling Window Average.
