NOTE
Display of the ultimate pressure.
Due to sensor accuracy, the minimum displayed value of the ultimate pressure is 5
mbar preceded by the symbol "<", which means that the actual value is lower than dis-
played.
The ultimate pressure of the machine is indicated on the nameplate (NP).
7.3 Ecomode
The Ecomode stops the machine when the inlet pressure has reached the preset "eco-
mode pressure" within a defined time delay and will restart once the inlet pressure ex-
ceeds the "restart pressure".
This mode is only available for “Role 2” people, see Role and User [►11].
To active and set the Ecomode:
• Go to “OPERATIONS” > “MODE”.
• Access to the second page.
• Press on Ecomode switch button (password required).
