Function
To find the energy saved by the GA VSD compressor compared to a compressor with load/no-load regulation
(L/NL) or compared to one with modulating control (MC). Consult the menu flow in section Control programs.

Starting from the Main screen (see Main screen menu):
• Press the key ‘Menu’ (F1).
• Press the arrow down key (1) until ‘Audit data’ is followed by a horizontal arrow.
• Activate the menu by pressing the tabulator key (2). Three submenus are shown: ‘Actual Values’,
‘Compare To L/NL’ and ‘Compared to MC’. By pressing the arrow down key (1) another submenu
appears: ‘Settings/Setup’. Only the submenus followed by a horizontal arrow are accessible.
‘Actual Values’ submenu
If scrolling to submenu ‘Actual Values’ and pressing key (2), the current load percentage will be shown
(compared to the maximum load). By pressing the arrow down key (1), the current power consumption is
shown.
‘Compare to L/NL’ or ‘Compared to MC’ submenu
The ‘Compare To L/NL’ or ‘Compared to MC’ submenu is only accessible if a test period is running or
finished, see below.
If scrolling to one of these submenus and pressing key (2), following data are shown:
• ‘Capacity’: average flow during the test period
• ‘Capacity’: average flow (percentage) compared to the maximum load
• ‘Package Power’: average power consumption during the test period
