7.2.4. Automatic operation negative pressure
In the automatic operation negative pressure, the set point in Pascal for the negative
pressure is set with the "+" and "-" keys.
By comparing the entered set value 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 screen saver mode. The
setpoint (target) and the actual value (actual) for the negative pressure as well as the filter
occupancy are displayed here.
The screen saver mode can be terminated by tapping the "close" button.
