AF Control
Re-Optimization Sensitivity
Notes:
1. Use only Factory Defaults. Defaults other than above may effect chiller reliability
2. 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.
