Performance indicators: basic concepts

The module checks the effective device regulation capacity, indicating:

when variable data is over and under a limit
when a value remains under the minimum limit or over the maximum limit for an excessive period of time

Calculations are made considering the period set by the user that can take into account any defrost or non regulation periods (i.e.: when the device is off).

Devices can be grouped. The variables to be checked are set for each device template.

Report fields

Total time	Analysis period actually used for calculations. Total time = Period - (Sum of defrost time) - (Sum of non regulation time).
Time under the limit	Variable duration under the Min limit.
% time under limit	% duration under the limit. The field has a blue background if the value is under the Min % limit.
Time over the limit	Variable duration over the Max limit.
% time over limit	% duration over the limit. The field has a red background if the value is over the Max % limit.
Medium	Variable average calculated over Total time.
Defrost time	Total defrost period duration.
% defrost time	% defrost periods of Total time.
ON time	Total regulation period duration.
% duty cycle	% regulation periods of Total time. % duty cycle = ON time / (Total time - Defrost time)
