Neptronic TSUB universal wall-mount controller BACnet points list

Updated 6 November 2026

Short answer

A wall-mount universal room controller with configurable inputs and outputs that speaks BACnet MS/TP. The BACnet guide lists 220 objects: inputs and outputs, mode, fan and occupancy commands, setpoints, demands per ramp, alarms and a large set of Cfg_ configuration objects. Which outputs and modes are used depends on how the ramps and inputs are configured.

This page lists 220 BACnet objects for the Neptronic TSUB universal wall-mount controller — 184 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Neptronic’s own free documentation, linked below.

BMS integration notes: Neptronic TSUB universal wall-mount controller

Integration in brief

Command occupancy with MSV.13 NsbOccCommand, the mode with MSV.1 and the fan with MSV.2, and write the setpoint to AV.9. To feed the room temperature from the BMS, set MSV.21 to Network and keep writing AV.1 ControlTemp within the AV.2 timeout. Read MSV.14, AV.1, the ramp demands and the AL_ alarm BVs.

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.

Enable & remote start

MSV.13 NsbOccCommand: Locally lets the controller follow its occupancy input; the other states force off, occupied/day or unoccupied/night from the BMS.

Heartbeat & communication loss

With MSV.21 Cfg_TempControlSource = Network, the BMS must keep writing AV.1 ControlTemp; if nothing arrives for AV.2 Cfg_NetworkTimeOut (0-60 min) the controller goes to OFF and AV.1 shows 999 °C in fault. With AV.2 = 0, AV.1 resets to the AV.9 setpoint.

Sensors & values from the BMS

Set MSV.21 Cfg_TempControlSource to Network (1) and write the room temperature to AV.1 ControlTemp (commandable).

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 TSUB universal wall-mount controller and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Neptronic TSUB universal wall-mount controller

How many BACnet points does the Neptronic TSUB universal wall-mount controller have?

This list has 220 BACnet objects: 4 analog inputs, 2 analog outputs, 118 analog values, 1 binary input, 5 binary outputs, 55 binary values, 1 file, 1 schedule, 32 multi-state values, 1 other. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Neptronic TSUB universal wall-mount controller BACnet points are writable?

184 of the 220 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 Neptronic TSUB universal wall-mount controller BACnet documentation?

The source is TSUB BACnet Guide (TSUB-BACnet Guide-250829 (V1.13)), revision 2025-08-29, published free by Neptronic at https://www.neptronic.com/controls/PDF/2025/TSUB-BACnet%20Guide-250829%20(V1.13).pdf.

What are the minimum BACnet points to integrate the Neptronic TSUB universal wall-mount controller?

Start with MV 13 NsbOccCommand (BMS occupancy command: local, off, occupied, unoccupied); MV 1 SystemMode (Mode: auto, heating, cooling, fan, off); MV 2 UserFanSpeedSelect (Fan speed: auto, low, medium, high); AV 9 TempSetPoint (Occupied/day temperature setpoint); MV 14 OccupancyStatus (Actual occupancy incl. override); AV 1 ControlTemp (Temperature used for control); AV 20 Heating1Demand (Heating ramp 1 demand, %); AV 35 Cooling1Demand (Cooling ramp 1 demand, %); BV 37 AL_FlowSwitch (Airflow alarm); BV 36 AL_ DirtyFilter (Filter change required).

How do I enable BMS control of the Neptronic TSUB universal wall-mount controller?

MSV.13 NsbOccCommand: Locally lets the controller follow its occupancy input; the other states force off, occupied/day or unoccupied/night from the BMS.

Does the Neptronic TSUB universal wall-mount controller need a BACnet heartbeat or have a communication timeout?

With MSV.21 Cfg_TempControlSource = Network, the BMS must keep writing AV.1 ControlTemp; if nothing arrives for AV.2 Cfg_NetworkTimeOut (0-60 min) the controller goes to OFF and AV.1 shows 999 °C in fault. With AV.2 = 0, AV.1 resets to the AV.9 setpoint.

Can the BMS supply sensor values to the Neptronic TSUB universal wall-mount controller?

Set MSV.21 Cfg_TempControlSource to Network (1) and write the room temperature to AV.1 ControlTemp (commandable).

How do I check these points on the real TSUB universal wall-mount controller?

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.
