Vertiv Liebert PEX4 precision cooling BACnet points list
Updated 6 November 2026
The Liebert PEX4 precision cooling reports to a BMS through a Liebert IntelliSlot card (IS-UNITY-DP, for BACnet IP or BACnet MS/TP). The object list has Binary Values for events, Analog Values for temperatures, humidity, setpoints and run hours, and Multi-state Values for states and control modes. Objects are created on the card when it discovers the unit, so only options fitted to the unit appear.
This page lists 198 BACnet objects for the Vertiv Liebert PEX4 precision cooling — 21 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Vertiv’s own free documentation, linked below.

BMS integration notes: Vertiv Liebert PEX4 precision cooling
Fit a Liebert IntelliSlot BACnet card (IS-UNITY-DP for BACnet IP or MS/TP), give it a unique device instance and let it discover the unit; the objects are then created automatically. Map the on/off and setpoint objects if the BMS controls the unit, and the status, main measurements and event objects for monitoring.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

| AV 1 | 5002_1 | Supply air temperature, °C | Read |
| AV 2 | 4291_1 | Return air temperature, °C | Read |
| AV 6 | 5028_1 | Return air humidity, %RH | Read |
| AV 487 | 5078_1_1 | Cooling output, % | Read |
| AV 423 | 5077_1_1 | Fan speed, % | Read |
Network setup
- The card needs a unique Device Instance Number; the device object represents the card, not the unit.
- The cards have no BBMD; IS-UNITY-DP and IS-IPBML support foreign device registration (BBMD address and time-to-live).
- IS-UNITY-DP adds BACnet MS/TP; IS-WEBADPT and IS-IPBML are BACnet IP only. Check the compatibility table (guide section 1.1.3) for the card your unit supports.
Watch out for
- Vertiv asks for no more than about two writes and two reads per second on average; do not rewrite setpoints continuously.
- No segmented responses: large ReadPropertyMultiple requests can fail, so split them.
- Only data the managed unit actually has is created on the card, so object counts vary by model and options.

Integration notes
- Tables 5.72, 5.73, 5.74, pdf pages 1661-1671 of the 2024 guide (printed page numbers are 4 lower).
- Object names are Vertiv data IDs (e.g. 5331_1); the description holds the guide's data label. Labels repeated for different sensors or circuits get the group name in brackets.
- Most temperature objects come in pairs: a °C object and a °F object (name ending _deg_F), usually at instance + 10000.
- The guide prints the same instance twice for: BV 651 (7552_1 and 7552_1_1); only the first is listed.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Liebert PEX4 precision cooling and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Vertiv Liebert PEX4 precision cooling
How many BACnet points does the Vertiv Liebert PEX4 precision cooling have?
This list has 198 BACnet objects: 86 analog values, 101 binary values, 11 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Vertiv Liebert PEX4 precision cooling BACnet points are writable?
21 of the 198 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official Vertiv Liebert PEX4 precision cooling BACnet documentation?
The source is Liebert IntelliSlot Modbus/BACnet Reference Guide (Modbus RTU and TCP, BACnet MSTP and IP) (SL-28170), revision 2024-04 (Rev 29), published free by Vertiv at https://www.vertiv.com/49fb41/globalassets/shared/liebert-intellislot-modbus-rtu-reference-guide-SL-28170_0.pdf.
What are the minimum BACnet points to integrate the Vertiv Liebert PEX4 precision cooling?
Start with MV 60 7536_1 (Monitoring on/off (1=on, 2=off)); AV 8 5331_1 (Supply air temperature setpoint, °C); AV 9 5333_1 (Return air temperature setpoint, °C); MV 71 7528_1 (Run / standby / off state); MV 72 4123_1 (Normal, warning or alarm state); AV 1 5002_1 (Supply air temperature, °C); AV 2 4291_1 (Return air temperature, °C); AV 6 5028_1 (Return air humidity, %RH); AV 487 5078_1_1 (Cooling output, %); AV 423 5077_1_1 (Fan speed, %).
How do I check these points on the real Liebert PEX4 precision cooling?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
