Figure 6.7 Setpoints, page 1 of 2
Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to maintain.
If the temperature falls below this point, unit will raise the refrigerant temperature to reduce the amount
of cooling.
The setting is intended to keep the room temperature above the setpoint. Without a proper setpoint, the
Liebert XDC can lower the room temperature too much, depending on the room dew point and load. This
setpoint will reduce the cooling to keep the room temperature above this desired temperature.
NOTE: This is not a true room temperature setpoint. The Liebert XDC has no heaters; it will try to cool
as much as possible. If the Liebert XDC is able to cool the room to this setpoint, it will reduce its cooling
action to try to keep the room temperature at or above this setpoint.
The default setting is 60°F (15.6°C). The range is 50-80°F (10-27°C).
For optimal cooling performance, the minimum temperature setpoint should be at least 1-2° below the
expected temperature at the remote sensors, which may affect placement of the remote sensors. If the
minimum temperature setpoint is set above the typical remote temperature sensor reading, it will reduce
the Liebert XD cooling output and, in extreme cases, cause erratic Liebert XD performance.
Spare Parts
Spare Parts—The spare parts lists contains a detailed description and part number that can be used to
order parts for the unit. These part numbers are specific to each model and option installed on the unit.
Event Log
Event Log—The event log displays all events and actions that have been generated by the unit. When
multiple units are networked you will see the event log of the whole system. Each event shows the unit
that generated the alarm, time and date stamp, a description and the event type.
