• Time interval
The time interval is in common for all the max/min demand channels. For this reason, this configuration
has to be done only once. Average values can either be calculated with sliding demand or no sliding.
The demand calculation will take place over the time interval defined. The interval will start in the moment
of selection and the following one will start after the time interval is over.
Select the time interval among one of the following options: 1, 2, 5, 10, 15 (default value), 30, 60 minutes.
After the configuration of time interval, it is needed to select the time sub-interval

Description
After the configuration of time interval, in case no sliding demand is
needed, please configure the time sub-interval as no sliding.
If no sliding is selected the average will be calculated over the intervals
01:00 - 01:15, 01:15 - 01:30, 01:30 - 01:45 etc...
After the configuration of time interval, in case of sliding demand it is
needed to setup a sub-interval, with measured interval that will slide
forward one sub interval at a time. The sub-interval must always be
smaller than the time interval the time interval must be evenly divisible
with the sub-interval. If for example an interval of 15 minutes and a sub-
interval of 1 minute is selected the average will be measured over the
intervals 01:00 - 01:15, 01:01 - 01:16, 01:02 - 01:17 etc...
