The WINTER and SUMMER time periods are con-
ventional seasons mainly used to manage in the
best way the different energy costs during the year.
The reminds at steps a), b), c) d) on page 20 are
also valid for the MULTI TARIFF function.
In the SINGLE TARIFF, only one period exists, referred to the
whole year.
In the DUAL TARIFF, the “year” can be divided into two peri-
ods: whole year and holidays.
In the multitariff, the “year” can be divided into 3 periods:
winter, summer and holidays.
