WM5-96 Instruction Manual
Let’s for example take into consideration the following tariff plan
decided by the energy supplier for December.
The working week is from Monday to Friday, while the weekend is
made by Saturday and Sunday. During the working days there are two
different tariffs with the following time periods: TARIFF 4 (T4) from 8
am to 5 pm, and TARIFF 3 from 5 pm to 8 am., while during the week
end there is only one time period and therefore a single TARIFF (T2).
The first thing to do is to program the week type
(4 - 6)
, the working
days will be indicated as follows: Monday (W), Tuesday (W),
Wednesday (W), Thursday (W), Friday (W). While the weekend
(Holidays) will be indicated as: Saturday (H), Sunday (H). As a conse-
quence, the time periods relating to the working weeks will be divided
into the following lines
(8 - 13)
:
First line: START TIME = 00, END TIME = 8, START DATE = 01/12,
END DATE = 31/12, then select “WORKING” and TARIFF “3”.
Second line: START TIME = 8, END TIME = 17, START DATE = 01/12,
END DATE = 31/12, then select “WORKING” and TARIFF “4”.
Third line: START TIME = 17, END TIME = 24, START DATE = 01/12, END
DATE = 31/12, then select “WORKING” and TARIFF“3”. Moreover, a 4th
line will be necessary to identify the NON-WORKING days other than the
week end (Saturday and Sunday): for example December 25th and 26th.
Fourth line: START TIME = 00, END TIME = 24, START DATE = 25/12,
END DATE = 26/12, then select “HOLIDAY” and TARIFF “2”.
The periods are now programmed and the instrument will display the
window on the left.
The periods programmed as above only refer to the month of
December, therefore it’s necessary to set a tariff referring to the
remaining time period, which will be referred to as “T1”. In this case
you can refer to the default tariff
(14)
set as TARIFF “1”, so that the
instrument will automatically refer to TARIFF “T1” when no other pro-
gramming is present.

In the “time periods” table you have
at least 100 selection rows available.
