9.2.- Parameters
The unit's operation parameters are organized into groups or families according to their function.
The
Def.
column shows factory-set default parameters.
The pressure values featured on the table are expressed in
bar
and those for temperature in
ºC
. If the wizard
meanwhile selects another set of units (parameter
C09
), the unit will make the conversion automatically.
IMPORTANT:
C01, C02, C04, C05, C06, C08
and
C09
are read-only parameters, editable using the
INI wizard only.
