11.1 Control Interface
When the buttons on the Liebert iCOM
®
control have not been pressed for a short period, the display
backlight turns Off. Pressing any key will 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 alarms.
Whether the cooling unit is in a Liebert iCOM U2U network or is a stand-alone unit, the Status menu
will display only that cooling unit’s information. Any large display connected to a network can be used
to view any cooling unit on the network or to show an average view of the entire system of cooling
units (the system view is obtained by pressing the Right and Left arrow key from the unit view). The
unit information being viewed is displayed in the upper right corner of the screen (see
for
an example).
