Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options) BACnet points list

Updated 7 November 2026

Short answer

The DXR1.E10PL is a damper actuator with a built-in BACnet IP room controller and airflow sensor for VAV, VVT and fan-powered boxes. This entry is the HvacFnct31 object set: supply damper position, heating valve or 1-3 stage / modulating electric reheat outputs, supply air temperature and box differential pressure, KNX PL-Link room unit status, room operating mode, comfort and economy setpoints, an air quality setpoint, and the supply airflow setpoint, measured flow and min/max limits.

BMS integration notes: Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options)

Integration in brief

Command the room operating mode (MV 9) and the room setpoint (AV 54) at priority 15, then read room temperature, the heating/cooling state, supply airflow and the damper and heating positions.

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.

Enable & remote start

The doc says the room operating mode is normally controlled from the BMS and must be written at priority 15; scheduled or manual central commands also use priority 15.

Sensors & values from the BMS

With a KNX PL-Link room unit the room setpoint can be adjusted through AV 54; with a DXR1.M09PxZ plus QMX1.M34H combination AV 54 may only be monitored, not written.

Integration notes

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 OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options) and exports what it actually has to Excel — free.

Where is the official Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options) BACnet documentation?

The source is Zone Controller Actuator Variable Air Volume, Variable Volume Temperature, and Fan-Powered Box BACnet Objects (A6V14595742), revision 2025-05-29, published free by Siemens at https://sid.siemens.com/api/khub/documents/lI1Ts8xUke93FIiwBFgwSQ/content.

What are the minimum BACnet points to integrate the Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options)?

Start with MV 9 ROpMod (Room operating mode (protection/economy/comfort)); AV 54 SpTR (Room temperature setpoint, °F (priority 15)); AV 60 RTemp (Effective room temperature); MV 17 HCSta (Heating/cooling state); AV 100 VavSuAirFl (Measured supply airflow, cfm); AV 98 VavSuSpAirFl (Supply airflow setpoint, cfm); AO 0 VavSuPos (Supply damper position, %); AO 15 HclVlvPos (Hot water heating valve position, %).

How do I enable BMS control of the Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options)?

The doc says the room operating mode is normally controlled from the BMS and must be written at priority 15; scheduled or manual central commands also use priority 15.

Can the BMS supply sensor values to the Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options)?

With a KNX PL-Link room unit the room setpoint can be adjusted through AV 54; with a DXR1.M09PxZ plus QMX1.M34H combination AV 54 may only be monitored, not written.

How do I check these points on the real OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct31 (Supply air VAV with reheat options)?

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.
