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.
