Belimo Energy Valve V3 BACnet points list
Updated 6 November 2026
The Energy Valve V3 is a pressure-independent characterized control valve with a flow sensor and two temperature sensors, so it reports flow, delta T, power and heating/cooling energy. It talks BACnet MS/TP or BACnet IP. AO 1 is a % setpoint read as position, flow or power depending on ControlMode (MV 100); the setpoint only follows the bus when SpSource (MV 122) is Bus.
This page lists 62 BACnet objects for the Belimo Energy Valve V3 — 17 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 Energy Valve V3
Set MV 122 SpSource to Bus, pick the control mode in MV 100 (flow control by default) and the flow or power limits, then command AO 1 SpRel. Read flow, temperatures, delta T, power and energy, and watch BI 101 SummaryStatus and AI 100 ErrorState for faults.
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
Write MV 122 SpSource = 2 (Bus); the default Analog (1) follows the 0-10 V signal on wire 3. MO 1 Override can force close, open, nominal or max flow/power or motor stop and falls back to None after 2 hours.
Network setup
- Default device instance 1 (writable, 0-4194302).
- MS/TP: baud 9600-76800, default 38400; address 0-127, default 1; max 32 nodes without repeater; 120 ohm terminator.
- BACnet IP: UDP port 47808 by default; foreign device registration supported.
- Configure through the valve's built-in web server.
Watch out for
- Writable objects with instance 90 or above are stored persistently and should not be written cyclically.
- While air bubbles are detected the valve runs in position control regardless of MV 100.
- Max 5 active COV subscriptions, lifetime up to 12 hours.

Integration notes
- This is the older V3 object map; Energy Valve V4 uses a different, larger list.
- Flow, power and energy are each published in several units (l/min, m³/h, gpm, l/s, l/h; kW, kBTU/h, ton; kWh, MJ, kBTU, ton·h).
- AI 100 ErrorState bits: 0 sensor T1, 1 sensor T2, 2 flow sensor, 3 actuator cannot move, 4 flow with closed valve, 5 air bubbles, 6 flow not reached, 7 power not realized, 8 gear disengaged, 9 reverse flow, 10 MP communication faulty, 11 freeze warning.
- Value ranges may be limited further by the valve size (DN); see the product datasheet.
- Binary objects print state texts as 1/2 (No/Yes, OK/Not OK, None/Reset); kept as printed. BV 100 is printed with read access.
- Names printed with superscripts are written out here (AbsFlow_m3h for 'AbsFlow_m³h', V'max for V' with subscript max).
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 Energy Valve V3 and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Belimo Energy Valve V3
How many BACnet points does the Belimo Energy Valve V3 have?
This list has 62 BACnet objects: 34 analog inputs, 1 analog output, 14 analog values, 2 binary inputs, 1 binary value, 6 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 Energy Valve V3 BACnet points are writable?
17 of the 62 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 Energy Valve V3 BACnet documentation?
The source is BACnet interface description, Energy Valve V3, revision 2026-07, published free by Belimo at https://www.belimo.com/mam/general-documents/system_integration/BACnet/belimo_BACnet_Interface-description_Energy-Valve_V3_en-gb.pdf.
What are the minimum BACnet points to integrate the Belimo Energy Valve V3?
Start with AO 1 SpRel (Setpoint: position, flow or power per control mode); MV 122 SpSource (Must be Bus for AO 1 to take effect); MV 100 ControlMode (Position, flow or power control); AI 11 AbsFlow_lmin (Measured flow, l/min); AI 22 DeltaT_K (Coil delta T, K); AI 30 AbsPower_kW (Thermal power, kW); AI 31 E_Cooling_kWh (Cooling energy meter, kWh); AI 32 E_Heating_kWh (Heating energy meter, kWh); BI 101 SummaryStatus (Overall OK / not OK); AI 100 ErrorState (Bit-coded error flags).
How do I enable BMS control of the Belimo Energy Valve V3?
Write MV 122 SpSource = 2 (Bus); the default Analog (1) follows the 0-10 V signal on wire 3. MO 1 Override can force close, open, nominal or max flow/power or motor stop and falls back to None after 2 hours.
How do I check these points on the real Energy Valve V3?
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.
