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.
•The resistive touchscreen is used with a firm touch, or consider using a stylus when interacting
with the touchscreen.
•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 on 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.

1.2 Touchscreen Status Dial
The dial in the primary-control panel is divided into four, customizable, read-only sections that display
setpoints and environmental conditions for unit status at a glance. See Figure 1.2 below.
The center of the dial displays sensor readings and changes color according to alarm thresholds as the
readings rise and fall. When the cooling unit is powered-off, the center of the dial is gray.
For detailed descriptions of the sections and customizing the dial, see Customizing the status dial on
page106
Figure 1.2 Dial sections
ITEM DESCRIPTION
1
Upper-center sensor reading. Selected sensor reading.
NOTE: If the upper sensor reading has threshold settings, the dial background color will change color based on those thresholds. See
Dial Background-color Status Indication on the next page.
2 Right setpoint. Setpoint and control sensor used for setpoint calculations.
3 Right control sensor. Sensor selected for control.
4 Lower-center sensor reading. Single or multiple sensor readings. Cycle through readings by touching the displayed reading.

1.2.1 Dial Background-color Status Indication
The background color of the dial indicates whether or not the unit is powered-on, and it also responds to
threshold settings of the upper-center sensor reading, see Figure 1.3 below. Table 1.3 on the facing page
describes the background color displayed if the selected sensor reading has threshold limits set.
