8- Table of parameters and messages

The Def. column indicates the ex-works configured 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 equipment will make the conversion automatically.
