Technical Description
actual time for that interval will be longer than the interval time which could result
in a too big demand value). For the same reason the calculation of demand for an
interval is restarted if the channel is configured to store a minimum value and the
time is set forward within the interval or into another interval.
Demand values Each demand quantity is individually configurable to store up to the three highest or
lowest demand values, where each value use one demand channel configured to use
first, second and third maximum/minimum. If demand is configured to store only
one maximum interval, then only the interval with the maximum peak will be
recorded. If a demand quantity is configured to store three maximum in-tervals the
intervals with the three highest peaks are recorded.
Sliding demand A demand channel can also be configured as maximum sliding demand or mini-mum
sliding demand. A sub-interval time is set which divides the interval into a circular
array with a new mean value calculated at the end of every sub-interval. The
selectable sub-interval times for demand is a subset of the interval times and evenly
divisible with the selected interval time.
