Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) BACnet points list
Updated 28 October 2026
These Belimo valve actuators have an Ethernet port with a web server and BACnet IP. The BMS writes a 0-100 % setpoint to AO 1 and reads position, two sensor inputs and status. The setpoint can instead come from an analog signal on S1, chosen with SpSource.
This page lists 13 BACnet objects for the Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) — 5 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Belimo’s own free documentation, linked below.

BMS integration notes: Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP)
Set MV 122 SpSource to Bus and command AO 1 SpRel over BACnet IP. Read AI 1 position and BI 101 summary status. Sensor types are set over BACnet but must be confirmed on the web server.
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 |
|---|---|---|---|
| AO 1 | SpRel | Valve setpoint, 0-100 % | Command |
| MV 122 | SpSource | Must be Bus for AO 1 to take effect | Write |
| AI 1 | RelPos | Valve position feedback | Read |
| BI 101 | SummaryStatus | Overall OK / not OK alarm | Read |
Enable & remote start
MV 122 SpSource selects the setpoint: Bus uses AO 1, Analog uses the (0)2-10 V signal on S1 while BACnet stays available for monitoring. Analog setpoint needs Sensortype 1 = Active, confirmed on the web server. MO 1 Override can force Open, Close or MotStop.
Network setup
- BACnet IP (Annex J), with foreign device registration supported.
- Device instance, object name and location are writable; no default instance is stated.
Watch out for
- Out-of-range analog writes are clamped to the range limits without an error.
- Writes to read-only analog value objects are overwritten by the application without an error.
- Max 5 active COV subscriptions, lifetime up to 8 hours.
- No segmentation support.

Integration notes
- The PICS lists state texts without numbers; numbers here follow the printed order, starting at 1.
- Sensor type changes made over BACnet must be confirmed on the actuator web server.
- Sensor values are raw: 0/1 for a switch, ohm for a passive sensor, mV for an active sensor.
- Foreign device registration is supported for BACnet IP across subnets.
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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) and exports what it actually has to Excel — free.

Questions about the Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP)
How many BACnet points does the Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) have?
This list has 13 BACnet objects: 5 analog inputs, 1 analog output, 1 binary input, 2 multi-state inputs, 1 multi-state output, 3 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) BACnet points are writable?
5 of the 13 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 Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP) BACnet documentation?
The source is Protocol Implementation Conformance Statement IoT Product Range (T5-PICS IoT Product Range v1.0), revision 2017-10, published free by Belimo at https://www.belimo.com/mam/general-documents/system_integration/BACnet/belimo_BACnet_Interface-description_IoT_product_range_en-gb.pdf.
What are the minimum BACnet points to integrate the Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP)?
Start with AO 1 SpRel (Valve setpoint, 0-100 %); MV 122 SpSource (Must be Bus for AO 1 to take effect); AI 1 RelPos (Valve position feedback); BI 101 SummaryStatus (Overall OK / not OK alarm).
How do I enable BMS control of the Belimo IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP)?
MV 122 SpSource selects the setpoint: Bus uses AO 1, Analog uses the (0)2-10 V signal on S1 while BACnet stays available for monitoring. Analog setpoint needs Sensortype 1 = Active, confirmed on the web server. MO 1 Override can force Open, Close or MotStop.
How do I check these points on the real IoT Valve Actuators VxM24A-LP1 / VxR24A-LP1 (BACnet IP)?
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.
