The outdoor unit is applicable to the Liebert.PEX air-cooled series air conditioner. For details, refer to Liebert.PEX
Condenser User Manual.

1.4.3 iCOM Controller

The iCOM controller of the Liebert.PEX series air conditioner uses the LCD screen with blue backlight and 128 × 64
pixels, or selects the large screen with 320 × 240 pixels. The user interface operation is simple. The multi-level
password protection can effectively prevent unauthorized operation. It also provides power failure auto-restoration and
high & low voltage protection functions. The operation time of components is available through the menus. The
expert-level fault diagnosis system can automatically display the current fault information, facilitating the maintenance.
It can store up to 400 historical event records. There are two kinds of panels for option: one with common screen and
the other with large screen, as shown in Figure 1-3.

1.4.4 Remote Monitoring Software

Through the configured RS485 port or TCP/IP port, the Liebert.PEX air conditioner can communicate with the host
computer and receive the control of the host software.
