Lynxspring BZ122-LX configurable VAV controller (Onyxx LX) BACnet points list
Updated 12 November 2026Unofficial source
The BZ122-LX is a configurable (not programmable) VAV controller with an integrated actuator and airflow sensor that works with TZ series room sensors. Its BACnet MS/TP map is fixed: airflow and damper I/O, room and supply temperatures, occupied/unoccupied setpoints, airflow limits, five auxiliary outputs for reheat or fans, PID loops and configuration multi-states.
This page lists 112 BACnet objects for the Lynxspring BZ122-LX configurable VAV controller (Onyxx LX) — 75 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Lynxspring’s documentation hosted by Cochrane Supply, not by Lynxspring itself, so treat it as unofficial.

BMS integration notes: Lynxspring BZ122-LX configurable VAV controller (Onyxx LX)
Set the address and baud on the DIP switches, configure box type, airflow limits and auxiliary outputs, then command occupancy (MSV 24) and the occupied setpoints. Read room temperature, airflow, damper position and the validation error code.
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.

Network setup
- MS/TP address is set on DIP switch bank DS2 (1-127); baud on DS1: 010 = 9600, 110 = 19200, 001 = 38400, 011 = 76800.
- An EOL jumper terminates the MS/TP trunk on the last controller; a second jumper terminates the TZ sensor bus.
- Firmware updates use a USB-COM adapter or a USB to MS/TP converter cable.
Watch out for
- K-factor (AV 30) and duct area (AV 31) must match the box for airflow to read right.
- BV 10 saves objects to flash and restarts the controller; do not write it cyclically.

Integration notes
- The guide has no read/write column; access is inferred from its tags (Status = read-only; Cfg, User and Cmd = writable).
- The two binary outputs are printed as AO 3 and AO 4 (named BO_1 and BO_2).
- Some MSV state lists are printed in short form (for example "AI-1, AI-2, AI-3 or AI-4"); those are kept as printed rather than numbered.
- MSV 17 RoomT_Loc prints the reheat type state list (None, Elect. Reheat ...); kept as printed.
- PID loop objects LOOP0-LOOP9 are listed as LO with their printed action and default gains.
- Temperature units are listed as °F; the guide prints °F and °C ranges and the controller can be set to metric.
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 BZ122-LX configurable VAV controller (Onyxx LX) and exports what it actually has to Excel — free.

Questions about the Lynxspring BZ122-LX configurable VAV controller (Onyxx LX)
How many BACnet points does the Lynxspring BZ122-LX configurable VAV controller (Onyxx LX) have?
This list has 112 BACnet objects: 2 analog inputs, 5 analog outputs, 52 analog values, 7 binary values, 9 loops, 37 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Lynxspring BZ122-LX configurable VAV controller (Onyxx LX) BACnet points are writable?
75 of the 112 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 Lynxspring BZ122-LX configurable VAV controller (Onyxx LX) BACnet documentation?
Lynxspring does not publish it on its own website. This list comes from BZ122-LX Configurable VAV MS/TP - Installation and Wiring Guide, a copy hosted by Cochrane Supply at https://www.cochranesupply.com/media/assets/product/documents/Lynxspring/BZ122%20Installation%20and%20Wiring%20Guide.pdf. Ask Lynxspring or its representative for the current revision.
What are the minimum BACnet points to integrate the Lynxspring BZ122-LX configurable VAV controller (Onyxx LX)?
Start with MV 24 OccMode (Occupancy command); AV 12 RTSPclg_Occ (Occupied cooling setpoint); AV 13 RTSPhtg_Occ (Occupied heating setpoint); AV 41 RoomT (Room temperature); AI 5 zAirFlow (Measured airflow); AV 2 zActiveFlowSP (Active airflow setpoint); AO 2 zActMod (Damper position, %); AV 44 DSsupplyT (Discharge air temp after reheat); AV 39 ValidationErr (Configuration error code (0 = none)).
How do I check these points on the real BZ122-LX configurable VAV controller (Onyxx LX)?
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.
