E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201) BACnet points list
Updated 4 November 2026
The TES201, HTS201 and CDS201 are room sensors that report their measurements as BACnet MS/TP Analog Input objects. Which inputs exist depends on the model: temperature only, temperature plus humidity and dew point, or all of those plus CO2 (averaged and raw).
This page lists 6 BACnet objects for the E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from E+E Elektronik’s own free documentation, linked below.

BMS integration notes: E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201)
Give the sensor a unique device instance and MAC address, then poll or subscribe to the Analog Inputs for the model's measurements. Write a COV_Increment if you want COV notifications; it is off by default.
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 0 | T | Room temperature | Read |
| AI 1 | RH | Relative humidity (HTS201, CDS201) | Read |
| AI 3 | CO2 | Room CO2, averaged (CDS201) | Read |
Network setup
- Device object instance and name are writable and stored in non-volatile memory.
- ReinitializeDevice is protected by a password given in the PICS.
Watch out for
- COV reporting stays disabled until COV_Increment is set to a real number.
- Reliability turns to NO SENSOR if the measuring element is damaged or missing.

Integration notes
- Object list from the BACnet PICS 'Room Sensor RS485' (25.06.2021), sections 11-12. All objects are read-only except Present_Value while Out_Of_Service is true.
- Temperature and dew point can be switched to °F or K; the object description changes with the unit (for example 'Temperature [deg. C]').
- COV_Increment defaults to NaN, which disables COV reporting until a value is written.
- The manual lists the device object name as model + 8 unique characters (e.g. HTS201_XXXXXXXX); it is writable.
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 Room Sensor RS485 BACnet (TES201, HTS201, CDS201) and exports what it actually has to Excel — free.

Questions about the E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201)
How many BACnet points does the E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201) have?
This list has 6 BACnet objects: 5 analog inputs, 1 device. The exact set on a given unit depends on its firmware, installed options and configuration.
Which E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201) BACnet points are writable?
None of the listed objects are marked writable in the source documentation.
Where is the official E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201) BACnet documentation?
The source is BACnet PICS Room Sensor RS485, revision 25.06.2021, published free by E+E Elektronik at https://downloads.epluse.com/fileadmin/data/product/PICS/PICS_RoomSensor.pdf.
What are the minimum BACnet points to integrate the E+E Elektronik Room Sensor RS485 BACnet (TES201, HTS201, CDS201)?
Start with AI 0 T (Room temperature); AI 1 RH (Relative humidity (HTS201, CDS201)); AI 3 CO2 (Room CO2, averaged (CDS201)).
How do I check these points on the real Room Sensor RS485 BACnet (TES201, HTS201, CDS201)?
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.
