Belimo 6-way PI zone valve (C6..QP..+BAC) BACnet points list
Updated 12 November 2026Unofficial source
This 6-way zone valve switches one coil between a heating and a cooling circuit and limits flow in each sequence. A single setpoint AO 1 covers both: 0-33 % runs sequence 1 from Vmax1 down to zero, 67-100 % runs sequence 2 from zero up to Vmax2, and the middle is a dead band. It reports position, calculated flow, the active sequence and an actuator status. It is a different product from the 6-way EPIV.
This page lists 20 BACnet objects for the Belimo 6-way PI zone valve (C6..QP..+BAC) — 6 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Belimo’s documentation hosted by Tameson, not by Belimo itself, so treat it as unofficial.

BMS integration notes: Belimo 6-way PI zone valve (C6..QP..+BAC)
Write MV 122 SpSource = Bus, set Vmax1 and Vmax2 once, then command AO 1 using the split range (0-33 % sequence 1, 67-100 % sequence 2). Read MI 1 for the active sequence, AI 19 for flow and BI 101 for alarms.
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 | Single setpoint for both heating/cooling sequences | Command |

Enable & remote start
Write MV 122 SpSource = 2 (Bus). With Analog (the default) the valve follows the 0-10 V signal on wire 3.
Network setup
- MS/TP only: baud 9600-115200, default 38400; address 0-127, default 1.
- Default device instance 1.
- Max 32 nodes without repeater; the 120 Ω terminating resistor must be fitted externally.
- Configured with the Belimo Assistant App.
Watch out for
- Writable objects with instance 90 and above are persistent; don't write them on a regular basis.
- Setpoints between 33 and 67 % are a dead band with no flow.
- Max 5 active COV subscriptions.

Integration notes
- Flow values are calculated, not measured by a sensor.
- MV 121 sets the unit for AI 19, AI 109 and AV 119; default l/h.
- Minimum Vmax depends on the valve size (19-28 % of Vnom).
- MV 100 ControlMode is read-only and fixed at FlowCtrl.
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 6-way PI zone valve (C6..QP..+BAC) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Belimo 6-way PI zone valve (C6..QP..+BAC)
How many BACnet points does the Belimo 6-way PI zone valve (C6..QP..+BAC) have?
This list has 20 BACnet objects: 7 analog inputs, 1 analog output, 5 analog values, 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 6-way PI zone valve (C6..QP..+BAC) BACnet points are writable?
6 of the 20 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 6-way PI zone valve (C6..QP..+BAC) BACnet documentation?
Belimo does not publish it on its own website. This list comes from BACnet PICS 6-way PI zone valve (C6..QP..-..+BAC), revision 2023-05, a copy hosted by Tameson at https://storage.tameson.com/asset/Products/Manuals/EN/v2w7s_md99_belimo_bacnet_interface-description_6way-pi-zone-valve_en.pdf. Ask Belimo or its representative for the current revision.
What are the minimum BACnet points to integrate the Belimo 6-way PI zone valve (C6..QP..+BAC)?
Start with AO 1 SpRel (Single setpoint for both heating/cooling sequences); MV 122 SpSource (Must be Bus for AO 1 to take effect); MI 1 ActSequence (Shows which sequence is active); AI 19 AbsFlow_UnitSel (Calculated flow); AI 1 RelPos (Valve position feedback); BI 101 SummaryStatus (Overall OK / not OK alarm).
How do I enable BMS control of the Belimo 6-way PI zone valve (C6..QP..+BAC)?
Write MV 122 SpSource = 2 (Bus). With Analog (the default) the valve follows the 0-10 V signal on wire 3.
How do I check these points on the real 6-way PI zone valve (C6..QP..+BAC)?
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.
