Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) BACnet points list
Updated 6 November 2026
The USE-BACnet option gives Thermokon's sensor families a BACnet MS/TP interface. The description lists 107 objects: measured values (temperature, humidity and derived values, CO2, VOC, differential pressure and airflow, illuminance, atmospheric pressure, extra inputs), offsets, upper/lower scaling limits, channel assignment, airflow formula settings, service counters and LCD/traffic-light settings.
This page lists 107 BACnet objects for the Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) — 84 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 USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...)
Read the measured values the sensor type provides (AI 0 temperature, AI 1 humidity, AI 5 CO2, AI 8 differential pressure, AI 9 airflow ...). Offsets, limits and channel settings are commissioning values.
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
- The description gives each object an ID, access and description but no object name; the description is used as the name here.
- Which values exist depends on the sensor type; the data sheet of each product says which are available.
- Units for temperatures, flows and pressures follow AV 38 (1 = SI, 2 = Imperial); SI units are shown.
- The document prints AV 70 twice as "Correction factor Illumination 1" and once as "Offset Illumination 2", and uses AV 82/AV 83 both as channel numbers and as CO2/VOC mix percentage and NTC BETA value; the later sections (consistent with section 1.6) are used here.
- RW* objects are read-only on LI65+, DPA+, LDF+ and RDF+, where the DIP switches set them.
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 USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) 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 Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...)
How many BACnet points does the Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) have?
This list has 107 BACnet objects: 22 analog inputs, 85 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) BACnet points are writable?
84 of the 107 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 Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...) BACnet documentation?
The source is Description for USE-BACnet MS/TP, revision Rev. F, 19.08.2021, published free by Thermokon at https://www.thermokon.de/downloads/Software/Schnittstellenbeschreibung/BACnet/USE-RS485_BACnet_Manual.zip.
What are the minimum BACnet points to integrate the Thermokon USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...)?
Start with AI 0 Temperature 1 (Temperature); AI 1 Relative humidity (Relative humidity); AI 5 CO2 (CO2, ppm); AI 6 VOC (VOC, %); AI 8 Differential pressure 1 (Differential pressure 1, Pa); AI 9 Volumetric flow 1 (Airflow 1 (unit per AV 41)).
How do I check these points on the real USE-BACnet MS/TP option for Thermokon sensors (FTA+, LK+, DPA+, LI65+ ...)?
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.
