Load control request for scheduled control

Event description

The load control service provider submits a request for scheduled 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. 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. Scheduled controls must be sent only for the relay for which a base calendar has previously been sent using a calendar‑based load control request. For the time period covered by the scheduled control request, the meter or metering system will not execute the calendar‑based control; the scheduled control overrides it.

The time periods specified in the scheduled request use timestamps with time‑zone information, as in other Datahub events. Note: This differs from the approach used in calendar‑based load control requests.
