Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units BACnet points list
Updated 4 November 2026
NOVOS 3 and NOVOS 5 are wall-mounted room sensors and operating units with a BACnet MS/TP interface. They measure temperature and, depending on the variant, humidity, CO2 and VOC, and offer occupancy, setpoint and fan-stage inputs for the room controller in the BMS. Only the main operating values are BACnet objects; the rest is set through a configuration file written with Thermokon's uConfig tool.
This page lists 32 BACnet objects for the Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units — 21 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Thermokon’s own free documentation, linked below.

BMS integration notes: Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units
Set the MAC address and baud rate with the DIP switches, and the Device Offset ID if needed. Read the sensor AIs and the occupancy, setpoint and fan-stage objects and feed them to the room controller in the BMS; write the LED and icon objects to show states back to the user.
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 |
|---|---|---|---|
| BV 100 | Occupancy | Room occupied (button), also writable from the BMS | Write |
| AV 103 | Setpoint | Room setpoint set on the unit | Write |
| MV 104 | Fan Stage | Fan stage selected on the unit | Read |
| AI 500 | Temperature | Room temperature | Read |
| AI 501 | Relative Humidity | Room humidity (rH variants) | Read |
| AI 505 | CO2 | Room CO2 (CO2 variants) | Read |
| BI 514 | Digital Input | Window or other contact, 1 = closed | Read |
Network setup
- MAC address 1-127 and baud rate (9600-115200) are set on DIP switches; 8N1.
- Device instance = Device Offset ID (AV 4180) + MAC address.
- Most settings (setpoint range, fan options, offsets, LCD behaviour) are written as a config file with uConfig via BACnet file transfer (FILE 0).
Watch out for
- LED objects are not stored; write them again after the device restarts.
- Changing the unit system to imperial does not rescale the measured-value limits; adjust them by hand.

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- Object list from the 'Description of RS485 BACnet Interface NOVOS 3 / NOVOS 5' manual, rev D, pages 4-9. Object names are printed in square brackets in the manual; the brackets are dropped here.
- Which AI objects are present depends on the sensor variant (Temp, CO2 Temp, CO2 Temp_rH, CO2+VOC Temp, CO2+VOC Temp_rH).
- The icon objects (BV 16-27) apply to the NOVOS 5 LCD; the LED objects (MV 426-427) to units with an LED button.
- Temperatures switch to °F when the unit system is set to imperial in uConfig.
- The manual has no access column; R/W here is inferred from the descriptions.
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 NOVOS 3 / NOVOS 5 RS485 BACnet room operating units and exports what it actually has to Excel — free.

Questions about the Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units
How many BACnet points does the Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units have?
This list has 32 BACnet objects: 8 analog inputs, 2 analog values, 1 binary input, 13 binary values, 1 device, 1 file, 1 multi-state output, 5 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units BACnet points are writable?
21 of the 32 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 Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units BACnet documentation?
The source is Description of RS485 BACnet Interface NOVOS 3 / NOVOS 5, revision Rev. D, 18.06.2026, published free by Thermokon at https://www.thermokon.de/direct/alterra-base/mimes/get/3f7260a25eb0435a3.
What are the minimum BACnet points to integrate the Thermokon NOVOS 3 / NOVOS 5 RS485 BACnet room operating units?
Start with BV 100 Occupancy (Room occupied (button), also writable from the BMS); AV 103 Setpoint (Room setpoint set on the unit); MV 104 Fan Stage (Fan stage selected on the unit); AI 500 Temperature (Room temperature); AI 501 Relative Humidity (Room humidity (rH variants)); AI 505 CO2 (Room CO2 (CO2 variants)); BI 514 Digital Input (Window or other contact, 1 = closed).
How do I check these points on the real NOVOS 3 / NOVOS 5 RS485 BACnet room operating units?
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.
