1 GETTING STARTED WITH ICOM CMS
The web-based user interface for iCOMCMS 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. For details on first-time set-up and retro-fit installation,
see Installing and Connecting iCOMCMS on page 35.
1.1 Liebert iCOM CMS has 3 Main Features
•A web-based user interface providing remote connectivity to a unit-level display with full
read/write capabilities.
•BMS connectivity via Modbus RTU, Modbus TCP/IP and SNMP.
•Mobile cloud/Mobile app access to view status and notification information on a mobile device.
NOTE: You can control the unit using the web-based UI, including unit on/off, setpoints, and alarm set-
up. The mobile app, however, does not allow unit control. It is a read-only interface for notifications.
1.2 What Features Would You Like to Use?
You can use one or all of these features, and the following sections provide an outline of the steps to set-
up and get started using each one.
1.2.1 Access the web-based user interface
Place iCOMCMS on your corporate network by configuring the network settings using the Connection
Settings menu. See Connection Settings on page 25.
Once set-up, everyone using a computer with corporate-network access and provided with the assigned
IP address can open the web UI in a web browser.
1.2.2 Access the BMS protocols
To configure communication with your building-management system, use the BMS Setup menu. See
External Monitoring and Building-management systems on page 22.
1.2.3 Access the mobile cloud/mobile app
Place iCOMCMS on your corporate network by configuring the network settings using the
ConnectionSettings menu. See Connection Settings on page 25.
Then, register the iCOMCMS cooling unit using the Cloud Setup menu. See Registering with the
Administration Portal toAllowMobile-appUsers Access on page 41.
•Once the unit is registered, the e-mail address you used to register the device will receive a
password-change e-mail with the credentials to log-in to the iCOMCMS Administration Portal
(www.icomcms.com) and the mobile app.
1 Getting Started with iCOM CMS 5

•Visit the Administration Portal at icomcms.com, and log-in to manage the registered devices
and mobile-app users as follows:
•Create a division.
•Create a building and assign the building to a division.
•Assign the registered iCOMCMS unit to a building.
•Create users, define the user’s role (Administrator, Mobile-app only), set-up e-mail or
SMS-text notifications, and assign buildings to the user, which determines what units
they can view in the mobile app.
•The mobile-app users will get an e-mail with log-in credentials, and can download the
iCOMCMS mobile application and log in to receive notifications.
1.3 iCOM CMS web-based user interface
The web-based user interface speeds set up and installation and simplifies control of Liebert® cooling
units.
•User, service and advanced menus are password-protected to prevent unauthorized changes
to cooling-unit operation. See Logging-on to iCOMCMS and Unlocking controls on page 9.
•iCOMCMS ships with default settings for efficient and effective operation of most cooling-units
and is easily configured to meet any need.
•iCOMCMS requires a Google Chrome web browser version 50.0.xx or higher.
Figure 1.1 on the facing page, shows the controls and options available on the main display.

3 SERVICE AND ADVANCED OPERATION
NOTE: With the exception of managing passwords, which is only available to the advanced-level user,
the service and advance menu options are the same.
3.1 Editing setpoints for the cooling unit
Setpoints are the means by which cooling-unit operation is controlled.
NOTE: Setpoint adjustment is only available via the web-based UI (and the wall-mounted controller).
You cannot modify setpoints using the mobile app.
NOTE: The default minimum difference between heating and cooling setpoints is 5°F (2°C), and does
not allow the heating and cooling setpoints to be set inside this differential. To select setpoints for that
do not automatically adjust to the minimum difference, this differential must be zero. We recommend
that you set the differential to zero at system start-up. See Setting the Temperature Differential on
page 20.
To edit the setpoints:
1. Click > Setpoints.
The SETPOINTS panel opens.
2. Adjust the setpoint options, then click Save.
The setpoint is updated.

3 Service and Advanced Operation 19

3.1.1 Setting-up Auto Run Mode
To properly navigate communication between the web UI and the wall-mounted thermostat controls, a
2-step procedure is required:
•At the thermostat, set the temperature differential to 0º (zero).
•On the web UI, set the heating and cooling setpoints, then the AI run mode.
Setting the Temperature Differential
The default minimum difference between heating and cooling setpoints is 5°F (2°C), and does not allow
the heating and cooling setpoints to be set inside this differential. To select setpoints for that do not
automatically adjust to the minimum difference, this differential must be zero.
NOTE: If you are having an issue with discrepancies in the setpoints and readings, and setting the
temperature differential does not help, please contact technical support at 1-800-543-2778.
1. At the wall-mounted thermostat, open the flip door and press twice until flashes in
the Function Settings section of the display.
2. Press to set the differential to 0°, then press .
3. Press to exit the function set-up.
Setting Heating, Cooling Setpoints and AI Run Mode
Before selecting AI (Auto) run mode, you must set the heating and cooling setpoints to the same value.
You must be in the run mode of the setpoint when setting it.
1. Make sure the minimum difference between setpoints is 0°. See Setting the Temperature
Differential on page 20.
2. Select heating run mode and set the heating setpoint on the web UI:
•Click > Setpoints, then select the unit to configure.
•In Run Mode, select Heating.
•In Fan Speed, select the fan speed to use.
•In Temperature, select the temperature setpoint.
•Click Save.
3. Select cooling run mode and set the cooling setpoint on the web UI:
•In Run Mode, select Cooling.
•In Fan Speed, select the fan speed to use.
•In Temperature, select the temperature setpoint.
•Click Save.
4. In Run Mode, select AI, then click Save.
The status dial displays “AI” for about 2minutes, and the wall-mounted thermostat is un-
responsive to button presses during this time while the configuration is communicating. After
that, the web UI displays the run mode currently in use, and the wall-mounted thermostat
indicates “AUTO” mode.
