Start AutoLearn Flow

the period of time that the environment is
monitored to allow the system to decide
what flow thresholds are most appropriate.
When the AutoLearn has finished, the
levels are overwritten.
Cancel AutoLearn Flow
Cancel the AutoLearn Flow process.
Flow thresholds will remain at levels set
prior to commencing AutoLearn Flow.
