Appendix B: Setpoints And Alarm Settings By Line Id - Vertiv Liebert iCOM DP400/500 Installer/User Manual

Appendix B: Setpoints and Alarm Settings by Line ID

These tables list the parameters by the line identification assignments employed before the iCOM touchscreen. The tables
include range/options of the parameter, the factory default setting, and a description of the parameter function.
The line IDs are not listed in the User or Settings menus, only in the parameter directory. You can search the parameter list
to find the line ID and it's associated label and value in the iCOM user interface.
To search the parameters list:
1. Log in at the Service level, then touch
2. Enter a line ID or term in the Search field, and touch

Description
Setting
73 °F
23.0 °C
Selects the temperature that the cooling unit will maintain by applying cooling and/or reheats.
Temp Set value is the temperature that has been set by the User to control the temperature.
73 °F
"Temp Act" value is a read-only value that indicates if another routine, such as supply
23.0 °C
compensation, has internally modified the temperature controlling value. If compensation has not
be activated, the ACT and SET values will always match.
73 °F
23.0 °C
Selects the sensor that will control the cooling capacity; either chilled water valve, compressors,
Return
free cooling valve, or air economizer. Unloading-type compressors can be set to any type of
Sensor
sensor, however, fixed-style compressors can only be set to Return or Remote sensors.
48°F
Selects a humidity level that the cooling unit will maintain by removing or adding moisture to the
8.9 °C
air. The humidity setpoint will be represented in %RH or Dew Point value depending on what the
humidity control type is set for.
50 %RH
Defines which humidity value the setpoint will be compared with. The return sensor is equipped
Return with Temp/Humidity sensor and can calculate the dew point based on icom' s internal lookup table.
Sensor If a sensor other than the return sensor is selected, the iCOM will calculate the correct %RH based
on the sensor selected and its actual temperature reading.
Selects the humidity control calculation. If set to "Relative' , the unit will control the humidity without
considering any temperature deviations. If set to Predictive and Absolute, the control will consider
the temperature deviation from temperature setpoint so that a constant level of moisture is kept in
Predictive
the area based on the humidity sensor reading and the temperature deviation from setpoint. "Dew
Point" allows the iCOM controller to calculate the actual dew point of the space and to control the
humidity based on a user- entered dew point temperature.
