Veris TW2 Protocol Series temperature room sensor BACnet points list
Updated 6 November 2026
The TW2 is a wall temperature sensor on BACnet MS/TP (or Modbus). It reports room temperature; touchscreen models add a temperature setpoint, fan speed, occupancy override and display settings, all writable.
This page lists 11 BACnet objects for the Veris TW2 Protocol Series temperature room sensor — 10 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Veris’s own free documentation, linked below.

BMS integration notes: Veris TW2 Protocol Series temperature room sensor
Set the MS/TP address and BACnet mode on the DIP switches, then read room temperature; on touchscreen models also the setpoint, fan speed and override.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| AI 1 | Room Temperature | Room temperature | Read |
| AV 1 | Temperature Setpoint* | Occupant temperature setpoint, 0-50 | Write |
| BV 5 | Occupancy Override | Override button state: active = not occupied | Write |
| MV 2 | Fan Speed* | Occupant fan speed selection, 1-5 | Write |
Network setup
- BACnet MS/TP on RS-485: DIP switch ADDRESS positions 1-7 set the MAC (0-127 for BACnet), position 8 selects BACnet or Modbus.
- Baud rates for BACnet: 9600, 19200, 38400, 76800, set on the CONFIG DIP switch.
- Device instance = Vendor_ID followed by the MS/TP address (e.g. 133nnn); it can be rewritten in the device object.
Watch out for
- Occupancy Override logic is inverted: active means not occupied.

Object ID lookup: Veris TW2 Protocol Series temperature room sensor point IDs by name
Integration notes
- Names with * are preserved through power outages; avoid writing them cyclically.
- Touchscreen setpoint, fan speed, display and color objects only matter on touchscreen models.
- Occupancy Override is active when the room is NOT occupied (as printed).

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 TW2 Protocol Series temperature room sensor and exports what it actually has to Excel — free.

Questions about the Veris TW2 Protocol Series temperature room sensor
How many BACnet points does the Veris TW2 Protocol Series temperature room sensor have?
This list has 11 BACnet objects: 1 analog input, 2 analog values, 6 binary values, 2 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Veris TW2 Protocol Series temperature room sensor BACnet points are writable?
10 of the 11 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.
Where is the official Veris TW2 Protocol Series temperature room sensor BACnet documentation?
The source is TW2 Protocol Series Installation Guide (Z207938-0H), revision 2024-06, published free by Veris at https://download.se.com/files?p_Doc_Ref=Z207938.
What are the minimum BACnet points to integrate the Veris TW2 Protocol Series temperature room sensor?
Start with AI 1 Room Temperature (Room temperature); AV 1 Temperature Setpoint* (Occupant temperature setpoint, 0-50); BV 5 Occupancy Override (Override button state: active = not occupied); MV 2 Fan Speed* (Occupant fan speed selection, 1-5).
How do I check these points on the real TW2 Protocol Series temperature room sensor?
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.
