Tariff creation method
Your device performs validation checks as you enter tariff information; it prompts you to change the information that you have entered or set the tariff to disabled if the tariff configuration is invalid. These checks can include:
•Start and end times must be different (for example, you cannot create a tariff that starts at 02:00 and also ends at 02:00).
•Start time can only be earlier than end time for tariffs that are applied every day. You can create a daily tariff that starts at 06:00 and ends at 02:00, but these times are only valid for the Everyday tariff and invalid for the other tariff types.
•Start day must be earlier than end day if the days are in the same month. You cannot create a tariff that starts June 15 and ends June 12.
There are two methods of creating tariffs:
•Time of year tariffs divide the year into multiple sections (usually seasons), where each section has one or more day types. For example, a four tariff configuration using this method could have Summer and Winter seasons that also use different weekend and weekday tariffs.
•Daily tariffs can divide days by day of the week, a weekday, a weekend, or every day, and can specify the time of day. For example, a four tariff configuration could have every day in the year divided into
You can combine these methods if, for example you wanted to create a tariff that applies on Mondays from January 1 to June 30, from 09:00 to 17:00. However, since only one tariff can be applied at any time, you cannot use an everyday or weekday tariff type because you already specified a tariff for the time periods 09:00 to 17:00.
Depending on how you configure the tariffs and the maximum number of tariffs supported by your meter, you may not be able to assign tariffs for the entire year, potentially leaving time gaps that do not have any tariff assigned to them.
Example tariff configurations for a four-tariff system
In these examples, four tariffs are used to cover the entire year (there are no time periods that do not have an associated tariff).
Configuration 1: four tariffs with weekdays and weekends

1End time of 23:59 is actually 23:59:59, or just before midnight.
All weekend days fall into one of two different tariffs, depending on the date. All week days fall into one of two different tariffs, depending on the date. This configuration does not use tariffs based on the time of day, or any day types other than weekend or weekday.
Example dates and corresponding tariffs:
•Friday, June 29 = tariff 3
•Sunday, November 18 = tariff 1
