Introduction1.0INTRODUCTIONThe Liebert iCOM offers the highest capabilities in unit control, communication and monitoring ofLiebert mission-critical cooling units.Liebert iCOM may be used to combine multiple cooling units into a team that operates as a singleentity, enhancing the already-high performance and efficiency of Liebert’s units.Liebert iCOM is available as a factory-installed assembly or may be retrofitted on existing productswith SM, AM or AG controls. Large graphic display wall-mount versions of the control are availablefor remote operation and monitoring of cooling units.1.1FeaturesLarge and Small DisplaysThe Liebert iCOM is available with either a large or small liquid crystal display. The Liebert iCOM with small display has a 128 x 64 dot matrix screen that simultaneouslyshows two menu icons, along with descriptive text. This display is capable of controlling only theunit it is directly connected to. The Liebert iCOM with large display has a 320 x 240 dot matrix screen that shows up to 16menu icons at a time, as well as descriptive text. This display can be used to control a singlecooling unit or any cooling unit on a network, regardless of how it is connected—either integratedinto a cooling unit or simply connected to the network and mounted remotely.Liebert iCOM’s menu-driven display is used for all programming functions on each connected coolingunit. The Status menu shows the status of the conditioned space, such as room temperature andhumidity, temperature and humidity setpoints, alarm status and settings, event histories and thecurrent time.Figure 1Liebert iCOM componentsDirect Panel Mount Large Display and BezelWall Mount Large DisplayDirect Panel MountSmall Display and BezelLiebert iCOM Input/Output Board1

Liebert iCOM Display Components and Functions2.1Navigating Through the Liebert iCOM MenusLiebert iCOM shows icons and text for monitoring and controlling your Liebert cooling units ornetwork of cooling units. The number of icons and amount of text shown depends on the display size.2.1.1Control InterfaceWhen the buttons on the Liebert iCOM have not been pressed for a short period, the display backlightturns off. Pressing any key will turn the backlight on (wake up the screen) and display the Statusmenu of the last cooling unit viewed. The Status menu will show the cooling unit’s operationalmode(s), return air temperature and humidity readings, temperature and humidity setpoints and anyactive 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’sinformation. Any large display that is connected to a network can be used to view any cooling unit onthe network or show an average view of the entire system of cooling units.The Liebert iCOM has three main menus; User, Service and Advanced.The User menu contains the most frequently used features, settings and status information. TheService menu contains settings and features used to set up unit communications and for unitmaintenance. The Advanced menu contains settings used to set up the unit at the factory.NOTEMenu settings may be viewed without a password, but changing settings requires a password.The password for the User menu is 1490. The password for Service menu is 5010. For detailson entering a password, see Entering a Password on page 62.1.2Accessing SubmenusWhile the display is at unit status screen, press either the Enter or down arrow key to display theUser menu. To access the Service menu, press the right arrow key. Pressing the right arrow key againwill display the Advanced menu. For navigating to the sub-menus from each main menu, press Enterkey and then the appropriate arrow key. Pressing the Enter key again to access the menu items.Figure 5Menu tree—Small display, stand-alone or networkedStatus MenuUnit 1 ViewUser MenuService
