E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) BACnet points list
Updated 12 November 2026Unofficial source
The EE800D is a room transmitter for CO2, relative humidity and temperature that works as a BACnet MS/TP smart sensor. Besides the measured values it calculates dew point, frost point, absolute humidity, mixing ratio, enthalpy and vapor pressure, each as its own Analog Input.
This page lists 10 BACnet objects for the E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of E+E Elektronik’s documentation hosted by Instrumart, not by E+E Elektronik itself, so treat it as unofficial.

BMS integration notes: E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP)
Set a unique device instance and MAC address, then poll the Analog Inputs. Most jobs only need temperature, humidity and averaged CO2.
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 | Read |
| AI 8 | CO2 | Room CO2, averaged | Read |
| AI 3 | Td | Dew point, calculated | Read |
Network setup
- Device instance (0-4194302) and device name are writable and kept in non-volatile memory; the default name is the model plus 8 unique characters.
- RS485 settings are one writable string property, default "38400-8n1"; baud 9600-115200, 8 data bits, no parity, 1 stop bit fixed.
- Max Master is writable, up to 127.
- ReinitializeDevice and DeviceCommunicationControl need the password printed in the PICS.
Watch out for
- Present_Value is only writable while Out_Of_Service is true; the value then defaults to 50.0.

Integration notes
- Object list from the PICS sections 11-12 (v1.2, dated 19.5.2015).
- The PICS says CO2raw is only for special applications that need a faster response.
- Units are selectable per object; the object description changes with the unit.
- All objects are read-only except Present_Value while Out_Of_Service is true.
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 EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP)
How many BACnet points does the E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) have?
This list has 10 BACnet objects: 10 analog inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) BACnet points are writable?
None of the listed objects are marked writable in the source documentation.
Where is the official E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP) BACnet documentation?
E+E Elektronik does not publish it on its own website. This list comes from BACnet PICS EE800D (PICS_EE800D v1.2), revision 19.5.2015, a copy hosted by Instrumart at https://www.instrumart.com/assets/ee-ee800-co2-temperature-rh-transmitter-bacnet-protocol-implementation.pdf. Ask E+E Elektronik or its representative for the current revision.
What are the minimum BACnet points to integrate the E+E Elektronik EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP)?
Start with AI 0 T (Room temperature); AI 1 RH (Relative humidity); AI 8 CO2 (Room CO2, averaged); AI 3 Td (Dew point, calculated).
How do I check these points on the real EE800D room CO2, humidity and temperature transmitter (BACnet MS/TP)?
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.
