Figure 54 Supply Compensation in Unit View
During normal operation, as the rack temperature increases above the fan temperature setpoint, the
fan speed will increase until it reaches 100% speed. 100% fan speed is achieved once the controlling
temperature reaches a value equal to 100% of the fan control band, or S116 Fan Setpoint + 1/2(S150
Fan Deadband) + 1/2(S149 Fan Temp Prop Band).
