Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for Liebert table 27 units: 73 objects (18 AI, 16 AO, 33 BI, 6 BO), all polled. Inputs give temperature, humidity, cooling, heating, humidify, dehumidify, economizer, stages, % capacity, unit status and the alarm bits; outputs set the setpoints, tolerances, alarm limits and delays, and switch the unit on/off and reheat/humidifier lockouts.

This page lists 73 BACnet objects for the Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX — 22 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Contemporary Controls’s own free documentation, linked below.

BMS integration notes: Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX

Integration in brief

Turn the unit on with Unit ON (BO 65) and off with Unit OFF (BO 64), write the temperature and humidity setpoints, then read temperature, humidity, % capacity and the alarms.

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 Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX

How many BACnet points does the Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX have?

This list has 73 BACnet objects: 18 analog inputs, 16 analog outputs, 33 binary inputs, 6 binary outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX BACnet points are writable?

22 of the 73 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 Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile Liebert_Table_27_b (Liebert_Table_27_b_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/Liebert_Table_27_b_LX.zip.

What are the minimum BACnet points to integrate the Contemporary Controls Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX?

Start with BO 65 Unit ON (Unit on command); BO 64 Unit OFF (Unit off command); AO 66 Temperature Setpoint (Temperature setpoint (control)); AO 68 Humidity Setpoint (Humidity setpoint (control)); AI 10 Unit Status (On / Off) (Unit status (on/off)); AI 1 Temperature (Unit temperature reading); AI 2 Humidity (Unit humidity reading); AI 9 % Capacity (Cooling capacity, %); BI 24 High Temperature (High temperature alarm); BI 20 Loss of Airflow (Loss of airflow).

How do I check these points on the real Liebert Table 27 units (LAM, Challenger 3000, Deluxe System/3, Himod, ICS) via BASgatewayLX?

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.
