Neptronic AROB universal room / IAQ controller BACnet points list
Updated 6 November 2026
Short answer
AROB is a wall-mount room controller for temperature, humidity, CO2 and VOC with BACnet MS/TP. The BACnet guide lists 166 objects: user system modes and setpoints, sensor readings, calculated enthalpy and dew point, demands per function and output, OAT and airflow lockout and filter alarms, and configuration objects for the outputs and inputs.
This page lists 166 BACnet objects for the Neptronic AROB universal room / IAQ controller — 129 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 AROB universal room / IAQ controller
Integration in brief
Turn the controller on with MSV.1, pick the temperature mode with MSV.2 and write the cooling/heating setpoints AV.1/AV.2. Read AV.10 temperature, AV.11 humidity, AV.9 CO2, the demands and the filter/airflow 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.

Integration notes
- Multistate state texts are listed as printed in the guide (option names in order, without numbers).
- MSV.7 Cfg Object list mode (Integrator, Advanced, Factory) changes which objects are visible.
- Sensor values can be overridden with Out_of_Service where the W? column says so.
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 AROB universal room / IAQ 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 AROB universal room / IAQ controller
How many BACnet points does the Neptronic AROB universal room / IAQ controller have?
This list has 166 BACnet objects: 3 analog inputs, 2 analog outputs, 84 analog values, 3 binary inputs, 2 binary outputs, 46 binary values, 26 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Neptronic AROB universal room / IAQ controller BACnet points are writable?
129 of the 166 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 AROB universal room / IAQ controller BACnet documentation?
The source is AROB BACnet Guide (AROB-BACnet Guide_170920), revision 2017-09-20, published free by Neptronic at https://www.neptronic.com/Controls/IAQController/PDF/AROB-BACnet%20Guide_170920.pdf.
What are the minimum BACnet points to integrate the Neptronic AROB universal room / IAQ controller?
Start with MV 1 User main system mode (Controller off or on); MV 2 User Temp system mode (Temperature mode: off, cool, auto, heat); AV 1 User Cooling Setpoint (Occupied cooling setpoint); AV 2 User Heating Setpoint (Occupied heating setpoint); AV 10 Status Temp level (Room temperature); AV 11 Status Humidity level (Room relative humidity); AV 9 Status CO2 level (Room CO2, ppm); AV 17 Status Cooling Demand (Cooling demand, %); AV 18 Status Heating Demand (Heating demand, %); BV 7 Status Air Flow Switch Status (Airflow alarm).
How do I enable BMS control of the Neptronic AROB universal room / IAQ controller?
MSV.1 User main system mode turns the controller off or on; MSV.2-MSV.6 set the temperature, humidity, CO2, VOC and fan modes.
How do I check these points on the real AROB universal room / IAQ 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.
