7.0 USER MENU PARAMETERS
User menus report general cooling unit operations and status. The user menu password is 1490.
The User menu parameter tables in this manual may differ from the display on your cooling unit. The
Liebert iCOM functions with several Liebert Precision Cooling units, each with its own set of control
commands. In addition, the Liebert iCOM firmware is being updated constantly. As a result, the User
menu parameter tables in this manual may differ from the display on your cooling unit. Check
www.liebert.com for the latest Liebert iCOM user manual updates.

Temperature Setpoint—Selects a temperature that the cooling unit will maintain by applying
cooling and or reheats.
Humidity Setpoint—Selects a humidity that the cooling unit will maintain by removing or adding
moisture to the air.
Humidity Control Type—Selects the humidity control calculation. Setting this parameter to
“Relative” will control the humidity without considering any temperature deviations. “Predictive” and
“Absolute” control consider the temperature deviation from temperature setpoint so that a constant
level of moisture is kept in the area based on the humidity sensor reading and the temperature
deviation from setpoint.
Supply Sensor—Enables or disables the supply air temperature sensor. This sensor is an optional
sensor that can be ordered from the factory (see 3.7 - Supply Control).
Supply Setpoint Temp Value—Selects the discharge air setpoint (see 3.7 - Supply Control).
Backup Temperature Setpoint—Selects a temperature setpoint that will be activated in the event
of a BMS time-out or a customer input signal. The BMS timer and/or the customer input must be
configured for this parameter to activate.
