The extended pin settings show how to increase or decrease the required CFM on the Hi-Velocity-HE fan coil for fine tuning.
The chart illustrates the CFM difference achieved changing pins 6, 7, and 8. Only these three pins are modified to increase or
decrease the CFM based upon the selected tonnage of pins 1 through 4.
