This instrument may prove to be indispensable for consumers using a fixed consumption schedule. The scheduler algorithm runs once every cycle, ensuring that the energy (electricity, gas, water, etc.) consumption of all the consumers it is monitoring stays within the domain of EMIN…EMAX in every given cycle (of 15 or 60 minutes) that is, neither over- or underconsumption occurs.
The device makes an estimate of the total energy consumption for the cycle based on the monitored values of consumption. Depending on whether this estimate is positive or negative, the VMAX decides to turn consumers on or off in order to conform to the schedule. The priority sequence of consumers can be set beforehand.
Every measurement cycle begins with an adjustable length time out, since the initial estimate of the first few minutes can be inaccurate. The duration of the time out can be set between 1 and 15 minutes (in practice, 3-4 minutes are sufficient), after which the maxlimiting algorithm continues with adjustable cycles (1-60 seconds).
