1 GETTING STARTED WITH ICOM™
The Liebert® iCOM™ offers the highest capability for unit control, communication, and monitoring of Liebert® Thermal
Management units. It is available factory installed on new units and assemblies or may be retrofitted in existing units.
1.1 Touchscreen Display and User Interface
The Liebert® iCOM™touchscreen and user interface speeds set up and installation and simplifies control of Liebert® thermal
management units, literally putting cooling system monitoring and management at your fingertips.
•User and service menus are password protected to prevent unauthorized changes to cooling unit operation.
•The touchscreen is back lit and auto-dims after a period of non-use, then turns off. Touch the screen to
illuminate the main screen.
•iCOM™ships with default settings for efficient and effective operation of most cooling units and is easily
configured to meet any need.
•iCOM™menus and displays are based on the options installed on the cooling units that it monitors and
manages.

through iCOM™, if the BMS remote monitoring system is sending a command to turn off the unit, the cooling unit
remains off.
NOTE: You must be logged in to access the menu options. See Powering On the iCOM™and Logging In/Unlocking
Controls on the previous page.
To Power On the Unit
