Vertiv Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) BACnet points list

Updated 6 November 2026

Short answer

The Liebert Mini-Mate2 1-5 ton and 8 ton map is a short legacy list: unit status, temperature and humidity readings and setpoints, an on/off control word and alarm words where several alarms share one object as bits. Only use it with the card variant named in the title.

This page lists 48 BACnet objects for the Vertiv Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) — 11 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 Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card)

Integration in brief

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.

Integration notes

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 Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) and exports what it actually has to Excel — free.

Questions about the Vertiv Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card)

How many BACnet points does the Vertiv Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) have?

This list has 48 BACnet objects: 20 analog values, 20 binary values, 8 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Vertiv Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) BACnet points are writable?

11 of the 48 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 Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card) 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 Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card)?

Start with AV 4 bc01_1 (Control word: unit on/off and lockouts (bit-coded)); AV 9 bs10_1 (Return air temperature setpoint, °C); AV 10 bs12_1 (Humidity setpoint, %RH); AV 5 bs01_1 (Inlet air temperature, °C); AV 6 bs02_1 (Return humidity, %RH); AV 8 bs09_1 (Temperature control capacity, %); AV 1 ba01_1 (Alarm word 1 (bit-coded)).

How do I check these points on the real Liebert Mini-Mate2 1-5 ton and 8 ton (IntelliSlot Unity card)?

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.
