Note:
AF Re-optimization Sensitivity
- Every 30 minutes the optimizing
algorithm compares the current value of the inlet guide vane position
to the value that was stored after the last re-optimization. If the
difference is greater than the AF Re optimization Sensitivity setting,
re-optimization occurs. This value is adjustable from 0 to 100%,
where 0 would guarantee re-optimization every 30 minutes and
100% would guarantee no re-optimization.
