DUCTED UNIT BLOWER STATIC SETTING
Fan static is a parameter setting 1 – 9 in the wired controller default is 5. Making these adjustments will verify
airflow is acceptable and will allow the blower to modulate speed in Auto mode. Refer to controller owner's manual
for static adjustment.
Fan Static Setting of the Controller sets the max speed the blower can run at.
Total Static is measured to verify fan static is correctly set
SUGGESTED SET UP:
1. Leave Fan static set to default of 5 on the controller. Turn fan speed on the controller to high speed, then
measure the static pressure using a Magnehelic or digital manometer.
2. If the total static is .4 to .5 then the factory setting does not need to be adjusted.
3. If the total static pressure is .3 or below, then the fan static setting needs to be lower so that the unit does
not deliver more air than it needs to.
4. If the total static is .6 to .7 then adjust the fan static setting to 6 or 7 and recheck static pressure and make
did not increase over .9
5. 5. If the fan static is .8 or higher increasing the static pressure setting will only increase the total static
to .9 or higher therefore make sure all registers are open and make necessary ductwork modifications to
lower the total static pressure.
