Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for an ArgusVision managing boiler: 78 objects (41 AI, 28 AO, 7 BI, 2 BO), 60 polled by default. On top of the single-boiler block it adds the controller CH/DHW setpoints, outdoor-reset limits, dependent boiler state/status/error and firing rate, controller state/status/error and the cascade firing rate.

This page lists 78 BACnet objects for the Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX — 30 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 ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX

Integration in brief

Write the controller CH setpoint (and outdoor reset values if used) and boiler operation, then read controller state, supply temperature and cascade firing rate.

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 ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX

How many BACnet points does the Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX have?

This list has 78 BACnet objects: 41 analog inputs, 28 analog outputs, 7 binary inputs, 2 binary outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX BACnet points are writable?

30 of the 78 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 ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX BACnet documentation?

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

What are the minimum BACnet points to integrate the Contemporary Controls ebm-papst ArgusVision Trio Managing Boiler via BASgatewayLX?

Start with AO 12 Boiler operation (Boiler operation command); AO 14 CH mode (CH mode); AO 56 Controller CH setpoint F (Controller CH setpoint, °F); AO 58 Controller DHW setpoint F (Controller DHW setpoint, °F); AI 52 Controller State (Controller state); AI 16 Supply temperature F (Supply temperature, °F); AI 76 Cascade Firing Rate (Cascade firing rate); AI 54 Controller Error Code (Controller error code); AI 6 Error Code (Boiler error code).

How do I check these points on the real ebm-papst ArgusVision Trio Managing Boiler 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.
