VAV - Regulation according to the deviation between the set point / external measurement
During operation at variable speed, the controller regulates the speed of the roof fan according to the set
point-measurement deviation. The set point is adjusted with the potentiometer built into the controller or
a CVF type external control. If the display is present on the roof fan, it will show you the flow rate in m
3
/h.
Example of slaving and VAV regulation according to measurement of the outside temperature:
VAV slaved according to the temperature sensor
