Filtering of the inputs

Both sensor or transmitter inputs “PressSensorIn” and "HighLimPressSensor” are smoothly filtered (by a first order filter) within the filtering time as defined by parameter SYS-01. This filtering results in a smooth fan speed control output to eliminate sudden duct static pressure variations, and thus provide a stable operation of the SPA_StatPressControl.


Description

Default value

SYS-01: filter time; 0 = disable

60 sec


Note: To disable smooth filtering of both sensor inputs, set SYS-01 to a value of  “0".
