AAON Stratus Unit Manager (Stratus controls) BACnet points list

Updated 12 November 2026

Short answer

Stratus is AAON's newest unit control platform; the Stratus Unit Manager connects to a BACnet MS/TP trunk or to Ethernet for BACnet IP. Its BACnet map is compact: 57 analog values (temperatures, humidity, airflow, fan and refrigeration modulation, active setpoints, plus writable setpoints at AV 10003-10009), 43 binary values for status, sensor and safety alarms, 4 multistate values for application, mode and occupancy, an occupancy schedule object and a schedule-driven binary input.

This page lists 106 BACnet objects for the AAON Stratus Unit Manager (Stratus controls) — 9 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from AAON’s own free documentation, linked below.

BMS integration notes: AAON Stratus Unit Manager (Stratus controls)

Integration in brief

Connect the Unit Manager to MS/TP or Ethernet (BACnet IP) and set the baud rate, MAC address and a unique device ID (and BBMD for IP) in Unit Settings. The BAS forces occupancy with MV 10001 or writes the Occupied Schedule, adjusts the occupied and unoccupied setpoints at AV 10004-10007 and can override the supply air setpoint with AV 10003. Read the mode, occupancy and alarm BVs.

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 10001 Force Occupancy (Auto, Force Occupied, Force Unoccupied) or the Occupied Schedule object (Schedule 2, which writes BI 1) set occupancy. BV 10002 can disable economizer operation (inverted logic).

Heartbeat & communication loss

AV 10003 Supply Air Setpoint Override must be written at least every five minutes or it is treated as invalid and the normal control mode takes over the supply air setpoint.

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 Stratus Unit Manager (Stratus controls) 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 AAON Stratus Unit Manager (Stratus controls)

How many BACnet points does the AAON Stratus Unit Manager (Stratus controls) have?

This list has 106 BACnet objects: 57 analog values, 1 binary input, 43 binary values, 1 schedule, 4 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which AAON Stratus Unit Manager (Stratus controls) BACnet points are writable?

9 of the 106 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 AAON Stratus Unit Manager (Stratus controls) BACnet documentation?

The source is Stratus BACnet Points Guide (Rev. A), revision 2026-11, published free by AAON at https://www.aaon.com/hubfs/Controls%20Literature/Stratus%20BACnet%20Points%20Guide%20Rev.%20A.pdf.

What are the minimum BACnet points to integrate the AAON Stratus Unit Manager (Stratus controls)?

Start with MV 10001 Force Occupancy (Occupancy: auto, force occupied or unoccupied); AV 10005 Occupied Cooling Setpoint (Occupied cooling setpoint, °F); AV 10004 Occupied Heating Setpoint (Occupied heating setpoint, °F); AV 10003 Supply Air Setpoint Override (Supply air setpoint override; rewrite every 5 min); MV 2 HVAC Unit Operating Mode (Current HVAC mode); BV 16 Occupied (Occupied status); AV 1 Mode Based Controlled Temperature (Temperature of the controlled point); AV 2 Supply Air Temperature (Supply air temperature); BV 43 Unit Cannot Run Alarm (Something is blocking unit operation).

How do I enable BMS control of the AAON Stratus Unit Manager (Stratus controls)?

MV 10001 Force Occupancy (Auto, Force Occupied, Force Unoccupied) or the Occupied Schedule object (Schedule 2, which writes BI 1) set occupancy. BV 10002 can disable economizer operation (inverted logic).

Does the AAON Stratus Unit Manager (Stratus controls) need a BACnet heartbeat or have a communication timeout?

AV 10003 Supply Air Setpoint Override must be written at least every five minutes or it is treated as invalid and the normal control mode takes over the supply air setpoint.

How do I check these points on the real Stratus Unit Manager (Stratus controls)?

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.
