Rate Calendar - Baer DLX User Manual

Rate calendar

The device has a rate calendar with a table for up to 100 public holidays.
The internal rates can be transmitted to external devices using the control
outputs (Out1 to Out4 or Rel1 and Rel2), e.g. to control other devices.
The rate program (settable) is stored in the form of an internal rate calen-
dar, which is hierarchically structured in three levels. The highest level de-
fines the seasons, the second level defines the weekly programs and the
lowest level defines the daily rate tables with the switching times for rates.
The definition of seasons allows up to six periods within one year (e.g.
summertime or wintertime) that can have different rate structures.
Example: Season 1:
Season 2:
Each active season requires the definition of a weekly program, which as-
signs the relevant daily rate switching tables (1..15) to weekdays. This can
be shown in a table as follows:
Season
In the table, weekdays are abbreviated as follows:
Mo = Monday
Fr = Friday
PH1, 2, 3 = Public Holiday Type 1, 2, 3
The three types of public holidays (PH1, 2 or 3) allow you to define single
weekdays to have special rates that are set in a separate definition table.
These public holidays have higher priority than normal weekdays and allow
one to consider holidays such as Easter, Christmas or other country spe-
cific holidays.
The sample entries in the above shown weekly program mean that in sea-
son 1 the daily rate table 1 shall be used all the time and in season 2 the
daily rate table 2 is valid. Of course, different daily rate tables can be used
for each weekday within a season, however only a maximum of 15 daily
rate tables are available.
These daily rate tables define which energy rate and maximum demand
rate shall be active at what time and also which control outputs must be
used to signal the rates to subsequent external devices. Each daily rate ta-
ble can have up to 16 rate switching times.
