5.5.2 Speed adjustment (unregulated VAV)
By potentiometer, or CVF type remote control.
By default the roof fan is set to its maximum speed, in bold in the table below.
The potentiometer in the controller allows you to change the speed of the turbine to adjust the flow rate.
The adjustment can be done with a CVF type remote control.
