EasyIO FW-08V VAV Controller (pre-built VAV application) BACnet points list
Updated 6 November 2026
The EasyIO FW-08V ships with one pre-built VAV application that is set up for cooling-only, staged electric reheat, hot water reheat, parallel fan, series fan or VVT damper boxes by configuration objects. It runs standalone or on BACnet IP over Ethernet or Wi-Fi. The object list covers occupied, standby and unoccupied setpoints, box flow settings, PID tuning, network inputs from the AHU/RTU, measured values, damper and reheat commands, status flags and alarms.
This page lists 100 BACnet objects for the EasyIO FW-08V VAV Controller (pre-built VAV application) — 79 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from EasyIO’s own free documentation, linked below.

BMS integration notes: EasyIO FW-08V VAV Controller (pre-built VAV application)
Join the FW-08V to the BACnet IP network over Ethernet or Wi-Fi, set the Config_* objects for the box type and airflow limits, then command OccupancyCommand (BV 1) and the occupied setpoints and read room temperature, airflow, damper position and the alarm flags.
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 |
|---|---|---|---|
| BV 1 | OccupancyCommand | Occupied/unoccupied command | Write |
| BV 10 | HeatLockoutCmnd | Global heat disable from the BMS | Write |
| AV 3 | OccCoolSp | Occupied cooling setpoint, °F | Write |

| AV 70 | RoomTemp | Room temperature, °F | Read |

| BV 52 | OccupancyStatus | Occupancy status | Read |
| BV 58 | LowCfmAlarm | Airflow below setpoint for 30 min | Read |
Enable & remote start
OccupancyCommand (BV 1) sets occupied or unoccupied. HeatLockoutCmnd (BV 10) disables heat globally (for example on outdoor temperature or no boiler) and MorningWarmUpCmnd (BV 6) starts morning warm-up from the central AHU/RTU.
Sensors & values from the BMS
OaTempIn (AV 10) takes outdoor temperature from the network for display only; NetDuctInletIn (AV 37) takes the duct inlet temperature from the AHU/RTU.
Network setup
- Set Config_MaxFlowSp, Config_MinFlowSp, Config_MaxHeatFlowSp and Config_Box_KFactor (AV 24-28) for the box.
- Config_P2P_BaseAddress (AV 42) groups VAV boxes that share an AHU for peer-to-peer data.
- BalFlowCommand (AV 36) and Config_BalCfmMaxFlow / Config_BalCfmMinFlow (AV 53/54) are used for air balancing.
Watch out for
- Config_* objects are setup values; don't write them cyclically.
- Leaving BalFlowCommand away from 1 (Auto) keeps the box in balancing mode and sets ManualFlowAlarm (BV 59).

Integration notes
- Objects are from the "BACnet Objects" list on pages 48-52 of the guide; the device object (EasyIoUnivVAV, device 14) is not listed as a point.
- The same objects cover every application type; Config_* objects pick the box type (VVT damper, floating actuators, parallel fan mode, local sensors).
- Values in brackets in the guide are metric conversions; the US units are shown here.
- The guide is published by EasyIO on the Johnson Controls documentation site.
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 EasyIO FW-08V VAV Controller (pre-built VAV application) 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 EasyIO FW-08V VAV Controller (pre-built VAV application)
How many BACnet points does the EasyIO FW-08V VAV Controller (pre-built VAV application) have?
This list has 100 BACnet objects: 68 analog values, 32 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which EasyIO FW-08V VAV Controller (pre-built VAV application) BACnet points are writable?
79 of the 100 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 EasyIO FW-08V VAV Controller (pre-built VAV application) BACnet documentation?
The source is FW-08V - VAV Application Guide v1.3 (v1.3), published free by EasyIO at https://docs.johnsoncontrols.com/bas/api/khub/documents/VlM5w6lLIWgV3sp5iwjhIg/content.
What are the minimum BACnet points to integrate the EasyIO FW-08V VAV Controller (pre-built VAV application)?
Start with BV 1 OccupancyCommand (Occupied/unoccupied command); BV 10 HeatLockoutCmnd (Global heat disable from the BMS); AV 3 OccCoolSp (Occupied cooling setpoint, °F); AV 4 OccHeatSp (Occupied heating setpoint, °F); AV 70 RoomTemp (Room temperature, °F); AV 78 BoxFlow (Measured box airflow, cfm); AV 79 EffectiveFlowSp (Active airflow setpoint, cfm); AV 100 Damper (Damper position, %); BV 52 OccupancyStatus (Occupancy status); BV 58 LowCfmAlarm (Airflow below setpoint for 30 min).
How do I enable BMS control of the EasyIO FW-08V VAV Controller (pre-built VAV application)?
OccupancyCommand (BV 1) sets occupied or unoccupied. HeatLockoutCmnd (BV 10) disables heat globally (for example on outdoor temperature or no boiler) and MorningWarmUpCmnd (BV 6) starts morning warm-up from the central AHU/RTU.
Can the BMS supply sensor values to the EasyIO FW-08V VAV Controller (pre-built VAV application)?
OaTempIn (AV 10) takes outdoor temperature from the network for display only; NetDuctInletIn (AV 37) takes the duct inlet temperature from the AHU/RTU.
How do I check these points on the real EasyIO FW-08V VAV Controller (pre-built VAV application)?
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.
