Belimo ZoneEase VAV zone control actuator (BACnet MS/TP) BACnet points list

Updated 6 November 2026

Short answer

ZoneEase VAV is a VAV damper actuator with a built-in differential pressure sensor and zone control applications (cooling, changeover, electric or hydronic reheat, parallel or series fan, CO2 and plain VAV). It runs on BACnet MS/TP. The BMS mostly sets the system mode, room setpoint, airflow limits and the heating/cooling changeover, and reads room temperature, airflow and status.

This page lists 97 BACnet objects for the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP) — 58 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 ZoneEase VAV zone control actuator (BACnet MS/TP)

Integration in brief

Pick the application in MV 2 during commissioning, then run the zone from the BMS with MV 1 SystemMode, AV 108 room setpoint and BV 1 changeover (where the application uses it). Read room temperature, airflow and damper position, and watch the status MIs. If a bus fail action is set, keep writing within the watchdog time.

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

MV 1 SystemMode switches the zone between Off, Active, Eco and Boost. In the VAV application (#9 in MV 2) the BMS sets the airflow directly with AV 102-104. MO 1 Override can force the damper or a fixed airflow, temperature or CO2 setpoint (types 8-13 use AO 10).

Heartbeat & communication loss

AV 130 BusWatchdog, 5-3600 s, default 120 s. If no write arrives within the timeout the actuator runs MV 130 BusFailAction (default None).

Sensors & values from the BMS

BV 1 BMS Changeover tells the zone whether the AHU supplies cool or warm air (all applications except #2, #8 and #9). Room temperature, humidity and CO2 come from the connected room operating unit or analog input, not from the BMS.

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 ZoneEase VAV zone control actuator (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP)

How many BACnet points does the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP) have?

This list has 97 BACnet objects: 16 analog inputs, 1 analog output, 47 analog values, 7 binary inputs, 12 binary values, 4 multi-state inputs, 1 multi-state output, 9 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Belimo ZoneEase VAV zone control actuator (BACnet MS/TP) BACnet points are writable?

58 of the 97 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 ZoneEase VAV zone control actuator (BACnet MS/TP) BACnet documentation?

The source is BACnet Interface description, ZoneEase VAV (VAV zone control actuator) (V1.7), revision 2025-05, published free by Belimo at https://www.belimo.com/mam/general-documents/system_integration/BACnet/belimo_BACnet_Interface-description_ZoneEase-VAV_V1_7_en-gb.pdf.

What are the minimum BACnet points to integrate the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP)?

Start with MV 1 SystemMode (Off / Active / Eco / Boost); AV 108 SpRmT_C (Room temperature setpoint, °C); BV 1 BMS Changeover (Heating or cooling air from the AHU); AI 20 RmT_C (Room temperature, °C); AI 12 AbsAirFlow_m3h (Measured airflow, m³/h); AI 1 RelPosDmp (Damper position, %); MI 101 StatusSystem (System health: sensor and config faults); MI 106 StatusActuator (Actuator status and errors).

How do I enable BMS control of the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP)?

MV 1 SystemMode switches the zone between Off, Active, Eco and Boost. In the VAV application (#9 in MV 2) the BMS sets the airflow directly with AV 102-104. MO 1 Override can force the damper or a fixed airflow, temperature or CO2 setpoint (types 8-13 use AO 10).

Does the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?

AV 130 BusWatchdog, 5-3600 s, default 120 s. If no write arrives within the timeout the actuator runs MV 130 BusFailAction (default None).

Can the BMS supply sensor values to the Belimo ZoneEase VAV zone control actuator (BACnet MS/TP)?

BV 1 BMS Changeover tells the zone whether the AHU supplies cool or warm air (all applications except #2, #8 and #9). Room temperature, humidity and CO2 come from the connected room operating unit or analog input, not from the BMS.

How do I check these points on the real ZoneEase VAV zone control actuator (BACnet MS/TP)?

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.
