Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct33 (with fan state, room units and sensors) 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 HvacFnct33 object set: supply damper, hot water valve (3-position, PWM or 0-10 V) and 1-3 stage or modulating electric reheat outputs, box differential pressure, air quality and humidity inputs, fan state inputs, KNX PL-Link room unit and sensor values, room operating mode, comfort/economy/protection setpoints, air quality setpoints, and the supply airflow setpoint, measured flow and limits.

BMS integration notes: Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct33 (with fan state, room units and sensors)

Integration in brief

Command the room operating mode (MV 9) and the room setpoint (AV 50) at priority 15, then read room temperature, heating/cooling state, supply airflow, fan state 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

Room temperature, humidity and air quality come from a KNX PL-Link room unit or sensor, or from wired inputs; the effective values are AV 57 (temperature), AV 55 (humidity) and AV 56 (air quality).

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 - HvacFnct33 (with fan state, room units and sensors) and exports what it actually has to Excel — free.

What are the minimum BACnet points to integrate the Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct33 (with fan state, room units and sensors)?

Start with MV 9 ROpMod (Room operating mode (protection/economy/comfort)); AV 50 SpTR (Room temperature setpoint, °F (priority 15)); AV 57 RTemp (Effective room temperature); MV 17 HCSta (Heating/cooling state); BI 4 FanSta (Fan state (on/off)); AV 97 VavSuAirFl (Measured supply airflow, cfm); AV 95 VavSuSpAirFl (Supply airflow setpoint, cfm); AO 0 VavSuPos (Supply damper position, %); AO 11 HclVlvPos (Hot water heating valve position, %).

How do I enable BMS control of the Siemens OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct33 (with fan state, room units and sensors)?

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 - HvacFnct33 (with fan state, room units and sensors)?

Room temperature, humidity and air quality come from a KNX PL-Link room unit or sensor, or from wired inputs; the effective values are AV 57 (temperature), AV 55 (humidity) and AV 56 (air quality).

How do I check these points on the real OpenAir Zone Controller Actuator DXR1.E10PL - HvacFnct33 (with fan state, room units and sensors)?

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.
