Real-time clock (RTC) control mode

In RTC control mode, the tariff switching is triggered by the real-time clock.

You can configure RTC control mode by using the display. The configuration includes the selection of schedule mode and the setup of 1 or 2 schedulers depending on the schedule modes.

The 2 schedule modes for RTC trigger are:

Day mode: weekdays and weekend share the same peak and peak-off duration and only 1 scheduler should be set.
Week mode: the tariff management of weekdays and weekends are controlled separately, and 2 schedulers should be set.

A scheduler supports a maximum of 4 time segments (Ta, Tb, Tc, and Td) for maximum 4 tariffs (T1, T2, T3, and T4). You can assign Ta, Tb, Tc, or Td to any tariff if any adjacent time segment has a different tariff. A valid scheduler always starts from Ta segment, and skipping time segments is not allowed.

In the setup of a schedule, you should define the tariff switching time for each target tariff. In the application, when the set switching time is reached, the tariff switches automatically.
