Vertiv Liebert Mini-Mate2 8 ton (L8T controller, iCOM CMS card) BACnet points list

Updated 11 November 2026

Short answer

The Liebert Mini-Mate2 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 8 ton (L8T controller, iCOM CMS card) — 8 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 8 ton (L8T controller, iCOM CMS card)

Integration in brief

Fit a Liebert iCOM CMS card (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 8 ton (L8T controller, iCOM CMS card) 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 Mini-Mate2 8 ton (L8T controller, iCOM CMS card)

How many BACnet points does the Vertiv Liebert Mini-Mate2 8 ton (L8T controller, iCOM CMS 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 8 ton (L8T controller, iCOM CMS card) BACnet points are writable?

8 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. The source has no read/write column, so this is inferred from object type.

Where is the official Vertiv Liebert Mini-Mate2 8 ton (L8T controller, iCOM CMS 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 8 ton (L8T controller, iCOM CMS card)?

Start with AV 4 bc01_1 (Control word: unit on/off and lockouts (bit-coded)); AV 11 bc02_1 (Temperature setpoint); AV 12 bc03_1 (Humidity setpoint); MV 10 bs27_1 (Unit status); AV 5 bs01_1 (Room temperature); AV 6 bs02_1 (Room humidity); AV 8 bs09_1 (Cooling capacity, %); AV 1 ba01_1 (Alarm word 1 (bit-coded)).

How do I check these points on the real Liebert Mini-Mate2 8 ton (L8T controller, iCOM CMS 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.
