EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) BACnet points list
Updated 7 November 2026
The HTN104 is an EBTRON thermal dispersion airflow and temperature transmitter with a BACnet MS/TP port. Its PICS object table lists three analog inputs (airflow, pressure, temperature) and four analog values (free area, baud rate, airflow and temperature traverse).
This page lists 7 BACnet objects for the EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) — 2 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from EBTRON’s own free documentation, linked below.

BMS integration notes: EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x)
Read airflow (AI 1), temperature (AI 3) and pressure (AI 2). Set the duct free area (AV 1) so the airflow reading is right.
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 | Airflow | Airflow (FPM, CFM, MPS or LPS) | Read |
| AI 3 | Temperature | Air temperature | Read |
| AI 2 | Pressure | Pressure (iWC or Pa) | Read |
Network setup
- BACnet MS/TP master at 9600, 19200, 38400 or 76800 baud (AV 2).
- No segmentation support.

Integration notes
- The object list comes from Table 1 of the 2011 PICS; units of the analog inputs are selectable (writable Units property).
- Access: Present Value is writable for AV 1 Free Area and AV 2 Baud Rate; the other objects are read-only (AI Present Value only when out of service).
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 HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) and exports what it actually has to Excel — free.

Questions about the EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x)
How many BACnet points does the EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) have?
This list has 7 BACnet objects: 3 analog inputs, 4 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) BACnet points are writable?
2 of the 7 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 EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x) BACnet documentation?
The source is HTN104 BACnet Protocol Implementation Conformance Statement (PIC_HTN104_1.x_R1C), revision 2011-03-24, published free by EBTRON at https://ebtron.com/wp-content/uploads/HTN104-1.x-BACnet-PICS.pdf.
What are the minimum BACnet points to integrate the EBTRON HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x)?
Start with AI 1 Airflow (Airflow (FPM, CFM, MPS or LPS)); AI 3 Temperature (Air temperature); AI 2 Pressure (Pressure (iWC or Pa)).
How do I check these points on the real HTN104 Thermal Dispersion Airflow / Temperature Transmitter (firmware 1.x)?
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.
