AFA4000/E
VAV Airflow Controller / p.101
If the airflow display is unstable following the calibration because of environmental turbulence
or sensor position and cannot be rectified, then it is possible to adjust the sensitivity of the
displayed value using the Display Smoothing parameter in the Cal Config menu. The controller
displays the velocity value as a rolling average over time and is adjustable over 1 to 100 seconds.
Note
The control output is not affected by the display smoothing so will provide fast response
control based on the sensor output. If the control output is unstable due to turbulence on
the sensor, then the output can be tuned to give stable control in the Econ Config menu
(see section 8.2).
