2.2 Main Unit Screen
The temperatures shown at the top of the main unit screen are determined by the configuration of the
Liebert iCOM. The values are based on which sensors are used for controlling airflow, cooling
capacity and humidification.
The data at the upper left of the screen can be either average or maximum rack temperature,
depending on the selection in the Remote Sensors Mode. The data at the upper middle of the screen
can be either dew point or relative humidity, depending on humidity control type.
Each unit can display individual remote rack sensors. The reading will be either an average or
maximum reading between the two sensors connected at each 2T sensor module.
The bar graph’s upper limit is set at 77°F (25.0°C)The lower limit is set at 68°F (20.0°C), the rack
inlet temperature range recommended by ASHRAE. When a rack temperature is at or above the
upper limit, the bar graph will be all black. When a rack temperature is at or below the lower limit,
the bar graph will be all white.

2.3 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.
2.3.1 Control Interface
When the buttons on the Liebert iCOM 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, or if the unit has a small display,
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 has three main menus; User, Service and Advanced.
