EBTRON IAQ-N200 wall-mount IAQ sensor BACnet points list
Updated 4 November 2026
The IAQ-N200 is an EBTRON wall-mount room sensor for relative humidity and temperature with an RS-485 port that runs BACnet MS/TP (or Modbus RTU when set by DIP switch). Its BACnet objects are a few Analog Inputs for the measurements plus Analog and Binary Values for baud rate and calibration.
This page lists 9 BACnet objects for the EBTRON IAQ-N200 wall-mount IAQ sensor — 7 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 IAQ-N200 wall-mount IAQ sensor
Set the MS/TP MAC address and baud rate on DIP switch SW1 before power-up, then read the measurement AIs. The AVs and BVs are only for calibration and setup.
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 | RH | Space relative humidity, % | Read |
| AI 2 | Temperature | Space temperature (°F unless set to °C) | Read |
Network setup
- MAC address defaults to 2; set 0-127 on SW1 switches 1-7 with power off.
- Device instance defaults to 2; DIP switch 8 on at power-up copies the MAC address into the instance, or write the Device Object_Identifier.
- MS/TP baud defaults to 76,800; 38,400, 19,200 or 9,600 can be set on SW1 switches 1-4 or through the Baud Rate AV.
Watch out for
- Writing gain/offset values changes the reading; the factory Gain/Offset Status BVs switch back to factory calibration.

Integration notes
- Points from Tables A2, A3-2 and A4 of the guide, which covers the IAQ-N100, IAQ-N200 and IAQ-N300 together.
- The AV and BV objects are calibration and setup values, not control points.
- Units are not printed per object; they are taken from the range and description columns.
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 IAQ-N200 wall-mount IAQ sensor and exports what it actually has to Excel — free. New to BACnet?

Questions about the EBTRON IAQ-N200 wall-mount IAQ sensor
How many BACnet points does the EBTRON IAQ-N200 wall-mount IAQ sensor have?
This list has 9 BACnet objects: 2 analog inputs, 5 analog values, 2 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which EBTRON IAQ-N200 wall-mount IAQ sensor BACnet points are writable?
7 of the 9 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 IAQ-N200 wall-mount IAQ sensor BACnet documentation?
The source is IAQ-Ny00-W Quick Installation Guide - Wall Mount Indoor Air Quality Sensors with RS-485 Network Output (Appendix A) (IG_IAQ-Ny00-W_R1B), revision 2016-05-12, published free by EBTRON at https://ebtron.com/wp-content/uploads/documents/IG_IAQ-Ny00-W.pdf.
What are the minimum BACnet points to integrate the EBTRON IAQ-N200 wall-mount IAQ sensor?
Start with AI 1 RH (Space relative humidity, %); AI 2 Temperature (Space temperature (°F unless set to °C)).
How do I check these points on the real IAQ-N200 wall-mount IAQ sensor?
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.
