values are stored in a FIFO (first in, first out) buffer. The buffer size is dictated by
the setpoint demand period. The average value of the buffer is calculated and stored
as the new demand value every minute. Demand for real and reactive power is only
positive quantities (+kW and +kvar).

This feature configures one or more of the output relays as a pulsed output. When
the programmed interval has transpired the assigned relay will be activated for 1
second.
This feature should be programmed such that no more than one pulse per second
will be required or the pulsing will lag behind the interval activation.
