Load control request for calendar control

Event description

The load control service provider submits a request for calendar‑based load control at the accounting point.

In the request, the service provider defines both the periods during which the meter’s load control relay is closed and the periods during which the relay is open. For each calendar day, up to six relay‑state changes may be defined within a 24‑hour period. The periods must always cover the entire full calendar day from midnight to midnight in Finnish time, taking into account daylight saving time. The periods must not overlap. The request must always include seven calendar days, from Monday to Sunday.

The time periods specified in the calendar request use Finnish local time, taking daylight saving time into account, without a time‑zone indicator. This approach ensures that the same request can continue to be applied across daylight‑saving transitions without the need to send new calendar‑based load control requests. The load control service provider must take this into consideration and therefore must not send control periods that begin or end between 03:00 and 04:00 during the change between summer time and winter time.
