for controllers of the “HVAC” seriesC051, C181, C625, C626, C627 additionally
to an application datum to be controlled, e.g. pressure, temperature, flow rate, humidity or speed.
The normalisation
implements an absolute or relative selection or display of an application datum,
is always carried out simultaneously for all codes indicated.
Adjustment
The display value is calculated from:
CXXX
C011
200
C500
C501
Example The speed setpoint is to be input and displayed as relative or absolute value.

Important
All codesindicated above are normalisedat the same time.
After a normalisation, the output frequency[Hz](C050)can onlybe recalculated withthe display
factorsC500 and C501.
