Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) BACnet points list
Updated 6 November 2026
EZvav is Nailor's factory-mounted VAV controller family, BTL-listed BACnet application specific controllers on BACnet MS/TP (up to 76.8 kbaud). Device instance, MAC and baud are set from the STE-8001W36 wall sensor without software. The object list covers space temperature and setpoints, occupied and unoccupied cooling and heating setpoints, airflow limits and calibration, fan and reheat outputs, discharge air control, AHU request flags, occupancy mode and the cooling, heating and DAT loops.
This page lists 74 BACnet objects for the Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) — 36 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Nailor’s own free documentation, linked below.

BMS integration notes: Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36)
Set the device instance, MAC and baud from the STE-8001W36 COMM menu. Monitor AV 1 space temperature, AV 3/AV 4 active setpoints, AV 24 actual airflow and AV 50 damper position (BAC-8205-36); the occupied setpoints are AV 5/AV 6 and MSV 1 is the occupancy mode. BV 1-3 and BV 7 are requests to the air handler.
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.

Network setup
- Device instance (seven digits), MAC address and baud are entered from the STE-8001W36 sensor: CNFG > COMM > DID, MAC, BAUD.
- BACnet MS/TP at up to 76.8 kbaud on EIA-485.
Watch out for
- Changing airflow calibration objects (K factor, correction slope/offset) changes measured flow; leave them to the balancer.
- Multistate state texts are not printed in the manual; read them from the controller.

Integration notes
- The controllers are KMC SimplyVAV models sold under the Nailor EZvav name; the list matches KMC's SimplyVAV list apart from a few names (e.g. AV 2 STPT REFERENCE, AV 12 STBY DIFF, AI 3 SPACE SET POINT) and a few objects KMC adds (AV 51, AV 54).
- The manual gives object, name and description only. Access is inferred: setpoint and configuration AVs writable, inputs, outputs and calculated values read-only.
- Not every object exists on every model; AV 48-50 are BAC-8205-36 only.
- Multistate values are printed as MSV1-MSV6 and loops as LOOP1-LOOP3; they are listed as MV and LO objects.
- BV 3 is printed with the description 'Need For AHU' (same as BV 1) and MSV 6 as 'Multi-state Value #6'.
- Source: BACnet objects, manual pages 44-46 (74 objects).
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 EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) and exports what it actually has to Excel — free.

Questions about the Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36)
How many BACnet points does the Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) have?
This list has 74 BACnet objects: 5 analog inputs, 2 analog outputs, 40 analog values, 6 binary outputs, 14 binary values, 3 loops, 4 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) BACnet points are writable?
36 of the 74 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. The source has no read/write column, so this is inferred from object type.
Where is the official Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36) BACnet documentation?
The source is EZvav Digital Controls - Installation and Operation Manual (IOM-EZVAVINST), revision 2016-10 (cover dated 7-2016), published free by Nailor at https://nailor.com/sites/default/files/documents/EZVAVINST_2.pdf.
What are the minimum BACnet points to integrate the Nailor EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36)?
Start with MV 1 OCCUPIED MODE (Occupancy mode of the box); AV 5 OCC CL STPT (Occupied cooling setpoint); AV 6 OCC HT SPT (Occupied heating setpoint); AV 1 SPACE TEMP (Space temperature); AV 3 ACT COOL STPT (Cooling setpoint in use); AV 4 ACT HEAT STPT (Heating setpoint in use); AV 24 PRI ACTUAL FLOW (Measured primary airflow); AV 50 DAMPER POSITION (Damper position); BV 1 NEED AHU (Box needs the air handler running).
How do I check these points on the real EZvav Digital VAV Controls (BAC-8001-36 / 8005-36 / 8007-36 / 8205-36)?
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.
