2�20 - CONTRACTS
In addition to the basic measurements, the device must carry out a set of calculations to ensure proper
billing, which gives rise to the concept of "contract".
A contract refers to the set of parameters that structure how the measurement to be taken by the
analyser is processed in order to reflect the contractual billing agreements.
2�20�1 - NUMBER AND ALLOCATION OF CONTRACTS
The meter has three contracts defined.
2�20�2 - CONTRACT PARAMETERS
A parameter is considered to be defined if it has an assigned value, and undefined if it is blank.
A parameter that is not used cannot have any value assigned from previous parameterisations, and
thus it will remain undefined.
Activation date
Date from which the meter – analyser has to use the contract parameters to calculate the data nec-
essary for billing.
Season
Season refers to each period of time into which a calendar year can be divided and during which the
billing conditions associated with it do not vary. The maximum number of seasons is 4.
Two types of seasons are considered:
Winter/Summer Season
. They split the year into two unique seasons bounded by the dates of the
official time change. No parameterisation of any kind is needed and they are automatically adjusted
each year.
Defined seasons
. Each season begins on a specific date, the end of which is the start date of the
next season, chronologically, regardless of the year. Each season is identified by a number starting
with 1, which increases by one unit, up to a maximum of 4.
Types of days
The days of the year are classified as:
Working�
Holidays�
A working day is Monday through Friday. They are all subject to the same tariff over the course of a
season.
A holiday is any Saturday, Sunday and any other days specified as such. They are all subject to the
same tariff over the course of a season.
Public holidays other than Saturdays and Sundays will be identified by date, the format of which may
contain wildcards.
