Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for an ArgusVision heat recovery unit: 25 objects (8 AI, 15 AO, 2 BI), 22 polled by default. Outputs set Modbus master, supply and exhaust fan speeds, the temperature setpoint, filter time and a two-block weekly on/off schedule; inputs give device type, error and warning codes, indoor and outdoor sensors and the bypass valve relay.

This page lists 25 BACnet objects for the Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX — 15 of them writable — with each object’s type, instance number, name, engineering units and access.

BMS integration notes: Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX

Integration in brief

Set Master is Modbus, write supply and exhaust fan speeds and the setpoint, then read indoor/outdoor temperatures, bypass state and the codes.

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 Heat Recovery Unit (Basic) via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX

How many BACnet points does the Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX have?

This list has 25 BACnet objects: 8 analog inputs, 15 analog outputs, 2 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX BACnet points are writable?

15 of the 25 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 Heat Recovery Unit (Basic) via BASgatewayLX BACnet documentation?

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

What are the minimum BACnet points to integrate the Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX?

Start with AO 8 Master is Modbus (Modbus as master (BMS control)); AO 10 Fan speed Supply (Supply fan speed); AO 9 Fan speed Exhaust (Exhaust fan speed); AO 11 Setpoint F (Temperature setpoint, °F); AI 13 Indoor sensor F (Indoor temperature, °F); AI 15 Outdoor sensor F (Outdoor temperature, °F); AI 17 Bypass Valve (relay) (Bypass valve relay); AI 6 Error Code (Error code); AI 7 Warning Code (Warning code).

How do I enable BMS control of the Contemporary Controls ebm-papst ArgusVision Heat Recovery Unit (Basic) via BASgatewayLX?

Master is Modbus (AO 8) hands control to the Modbus side; check the ArgusVision map for the value to write.

How do I check these points on the real ebm-papst ArgusVision Heat Recovery Unit (Basic) 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.
