Code Parameter Min Max Unit Default ID Description
P3.13.3.1 Function 1 9 1 333
1 = Only Source1 in use
2 = SQRT (Source1); (Flow = Constant x
SQRT (Pressure))
3 = SQRT (Source1- Source 2)
4 = SQRT (Source 1) + SQRT (Source 2)
5 = Source 1 + Source 2
6 = Source 1 - Source 2
7 = MIN (Source 1, Source 2)
8 = MAX (Source 1, Source 2)
9 = MEAN (Source 1, Source 2)

AI's and ProcessDataIn are handled as %
(0.00-100.00 %) and scaled according to
Feedback min and max.
Note: ProcessDataIn use two decimals.
