10.1 Navigating Through the Liebert iCOM Menus
Liebert iCOM shows icons and text for monitoring and controlling your Liebert cooling units or
network of cooling units. The number of icons and amount of text shown depends on the display size.
10.1.1 Control Interface
When the buttons on the Liebert iCOM control have not been pressed for a short period, the display
backlight turns off. Pressing any key will turn the backlight on (wake up the screen) and display the
Status menu of the last cooling unit viewed. The Status menu will show the cooling unit’s operational
mode(s), return air temperature and humidity readings, temperature and humidity setpoints and any
active alarm conditions.
If the cooling unit has a large display and is not on a network, whether it is networked or stand-alone,
the Status menu will display only that cooling unit’s information. Any large display that is connected
to a network can be used to view any cooling unit on the network or show an average view of the
entire system of cooling units.
The Liebert iCOM control has three main menus: User, Service and Advanced.
The User menu contains the most frequently used features, settings and status information. The
Service menu contains settings and features used to set up unit communications and for unit
maintenance. The Advanced menu contains settings used to set up the unit at the factory.
10.1.2 Accessing Submenus

highlight the first icon. Use the arrow keys to navigate through the icons. With the desired icon
highlighted, press the enter key to enter that submenu. Once in a Submenu, a list of parameters will
be displayed.
The up and down arrow keys may be used to scroll through the parameters page-by-page if the
submenu has multiple pages. To scroll item-by-item, press the Enter key and then use the up and
down arrow keys. Using the right or left arrow keys on large displays attached to a network will
