SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW) BACnet points list

Updated 6 November 2026

Short answer

The SAUTER ASV3 is a compact VAV controller: damper actuator, differential pressure sensor and airflow/temperature control in one unit, with BACnet MS/TP. Its object list exposes the hardware I/O, airflow and temperature setpoints and limits, PID tuning, room-unit (HMI) display settings, occupancy and cool/heat mode, plus many internal calculation objects.

This page lists 247 BACnet objects for the SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW) — 79 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from SAUTER’s own free documentation, linked below.

BMS integration notes: SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW)

Integration in brief

Command occupancy (BV 1) and cool/heat mode (BV 2), set the cooling and heating setpoints (AV 33, AV 37) or the airflow limits, and read the current airflow, damper position and room temperature. Damper and airflow overrides (BV 5 with AV 6, BV 6 with AV 12) are available for balancing.

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	VAV box Occupied/ unoccupied	Occupied/unoccupied: 1 = occupied	Write
BV 2	Cool/Heat mode	0 = cooling, 1 = heating	Write
AV 33	Cooling setpoint	Room cooling setpoint	Write
AV 37	Heating set point	Room heating setpoint	Write
AV 4	Current VAV airflow	Measured VAV airflow	Read
AV 5	VAV demand airflow	Airflow demand	Write
AV 61	Current VAV position feedback (0- 100)	Damper position feedback, 0-100 %	Read
AV 23	HMI Temperature sensor	Room temperature from the HMI room unit	Read
BV 10	No Airflow in main duct	Duct airflow alarm, 1 = no airflow	Read

Enable & remote start

Occupancy is BV 1 (VAV box Occupied/unoccupied); Cool/Heat mode is BV 2. Overrides: Override airflow control (BV 5) with Forced airflow control (AV 6), Damper override (BV 6) with AV 12.

Network setup

BACnet MS/TP: MAC address on DIP switch SW8 (switches 1-7, binary); baud on SW4 S1/S2: 9600 (off/off), 19200 (on/off), 38400 (off/on), 76800 (on/on).
SW4 S3 is the MS/TP end-of-line terminating resistor (factory off).
Device instance is set from the BMS, the PC tool or an EY-RU305F700xW room unit; AV 0 shows it (default 1000, the PC tool value must be divided by 10).
Sauter suggests no more than 22 controllers per MS/TP segment.

Watch out for

Many objects, mostly from AV 57 and BV 46 upward, are marked Internal use or Arithmetic Operation (calculation buffers); do not write them.
Airflow units follow Airflow display unit select (AV 29).
Cooling and heating airflow limits (AV 7-10) and setpoint limits are stored settings; do not write them cyclically.

Integration notes

From section 8, BACnet Objects List, tables 1-3 (manual pages 30-45).
Objects printed as "Not use" (18 objects) are left out. Objects marked "Internal Use" or "Arithmetic Operation" are kept but are not meant for BMS use.
Access follows the Read/Write column; rows with "-" or no entry are listed as read-only.
AV 47 and AV 90 print "0" in the unit column; it is left blank here. Several names are placeholders (AV-103, BV-35) with the meaning in the description.
The note under table 2: AV present values map to Modbus holding registers 40001-40500 as 10x integers; defaults in brackets are fixed and only change in DDC programming.

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 ASV3 VAV Compact Controller (ASV305BF7xxxW) 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 SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW)

How many BACnet points does the SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW) have?

This list has 247 BACnet objects: 6 analog inputs, 2 analog outputs, 112 analog values, 2 binary inputs, 4 binary outputs, 121 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW) BACnet points are writable?

79 of the 247 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 SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW) BACnet documentation?

The source is Manual SAUTER ASV3, published free by SAUTER at https://www.sauter-controls.com/wp-content/uploads/2021/08/Manual-SAUTER-ASV3.pdf.

What are the minimum BACnet points to integrate the SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW)?

Start with BV 1 VAV box Occupied/ unoccupied (Occupied/unoccupied: 1 = occupied); BV 2 Cool/Heat mode (0 = cooling, 1 = heating); AV 33 Cooling setpoint (Room cooling setpoint); AV 37 Heating set point (Room heating setpoint); AV 4 Current VAV airflow (Measured VAV airflow); AV 5 VAV demand airflow (Airflow demand); AV 61 Current VAV position feedback (0- 100) (Damper position feedback, 0-100 %); AV 23 HMI Temperature sensor (Room temperature from the HMI room unit); BV 10 No Airflow in main duct (Duct airflow alarm, 1 = no airflow).

How do I enable BMS control of the SAUTER ASV3 VAV Compact Controller (ASV305BF7xxxW)?

Occupancy is BV 1 (VAV box Occupied/unoccupied); Cool/Heat mode is BV 2. Overrides: Override airflow control (BV 5) with Forced airflow control (AV 6), Damper override (BV 6) with AV 12.

How do I check these points on the real ASV3 VAV Compact Controller (ASV305BF7xxxW)?

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.
