7.2.5. Automatic operation volume flow
In the automatic operation volume flow, the setpoint in Pascal is set with the "+" and "-"
keys in m³/h and cfm for the volume flow.
By comparing the entered setpoint with the permanently measured current actual value,
the speed of the fan is automatically adjusted meaning the fan runs automatically "up" or
"down".
The display shows the performance value in %, the measured negative pressure in Pa, the
volume flow in m³/h and cfm, and the absolute pressure after the filters in Pa.
After approx. 30 seconds without input, the display switches to the screen saver mode.
The set point (target) and the actual value (actual) for the volume flow as well as the filter
occupancy are displayed here.
The screen saver mode can be terminated by tapping the "close" button.
