Data type: Uint16
This is an array parameter with 4 elements, 1 for each sensor. A pressure filter time constant adjusts the dynamic of the reaction to the
actual pressure input to ensure reliable and stable status generation. Enter the pressure filter time constant. A higher value makes the
pressure signal more stable but less dynamic. A lower value makes the system more dynamic and allows signal spikes to affect the
control.

Parameters in this group contain the actual pressure levels and status information. The LCP can be configured to show the values of
these parameters in different display lines. Use parameter 0-20 Display Line 1.1 Small to parameter 0-24 Display Line 3 Large when
configuring the LCP to show different pressure values. The toggle function allows to show multiple pressure signals in the same LCP line.
Each of the sensors can have individual customized text followed by the sensor number and the actual pressure value. The status lines
indicate the status for all 4 sensor status or for individual sensors where 1 indicates an active ON status.
