ITRON Centron - Time-of-Use (TOU); TOU Schedules

Operation: C12.19 C1SD, C1ST, and C1SL Versions
54 CENTRON® Meter Technical Reference Guide
A self-read is programmed to initiate when any of the following occur:
 Before each self read is taken.
 Before each scheduled demand reset.
 Each manual reset using the Demand Reset button on the meter.
A Self-Read Register is programmed to initiate in one of three ways:
 Read on manual or electronic demand reset. When a demand reset is initiated, all
energy and maximum demand quantities are immediately transferred to non-volatile
memory.
 Read on a programmed day of the month (meters with timekeeping functionality only).
A specified date (1st - 28th) can be programmed into the meter to indicate the exact day
that a self-read is to be performed. On this date register readings are transferred to
nonvolatile memory.
If desired, an automatic demand reset can be performed after this self-read.
 Read on a programmable number of days since the last manual or automatic demand
reset (meters with timekeeping functionality only). If the selected number of days (1 to
255) passes without a demand reset, a self-read is initiated.
If desired, an automatic demand reset can be performed after this self-read.
A Self Reading Schedule can be set to occur in the following ways:
 Read daily
 Read n days after a demand reset
 Read on the nth day of the month
 Read n days before the end of the month
 Read on custom schedule
Time-of-Use
The Time-of-Use (TOU) functionality is designed for use in billing applications where
multiple rates (bins) are required for energy and demand.
TOU Schedules
Schedule information is programmed on a PC using the PC-PRO+ Advanced software
packages.
When using TOU functions on a meter, energy and demand registration are segregated into
time blocks during the day. Each time block can be one of four rate periods. In addition to
these four rate periods, a total rate is also available.
