Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus) BACnet points list

Updated 12 November 2026

Short answer

The Zoning RTU table covers a rooftop unit run by a Verasys zoning system. Through the SBH it exposes 111 objects in the 70,000 range: occupancy and unit enable, cooling and heating stage commands, enables and status, fan and economizer, discharge and duct pressure setpoints, network-written outdoor and zone values, temperatures and alarms.

This page lists 111 BACnet objects for the Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus) — 46 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Johnson Controls’s own free documentation, linked below.

BMS integration notes: Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus)

Integration in brief

Integrate through the Verasys Smart Building Hub: enable BACnet routing on the SBH, and the supervisor then sees each system bus device behind the SBH's MS/TP network. Map the enable and occupancy commands, the main setpoints and the status and alarm points.

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.

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 Verasys Zoning RTU (rooftop unit on the Verasys system bus) 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 Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus)

How many BACnet points does the Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus) have?

This list has 111 BACnet objects: 60 analog values, 51 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus) BACnet points are writable?

46 of the 111 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 Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus) BACnet documentation?

The source is Verasys BACnet over IP Integration User Guide (LIT-12013287), revision 2024-03-11, published free by Johnson Controls at https://docs.johnsoncontrols.com/bas/api/khub/maps/bQUUXbLn_sJI5F5XzKax0Q/attachments/ETDjFYqCzPvla4mPr0wdlw-bQUUXbLn_sJI5F5XzKax0Q/content.

What are the minimum BACnet points to integrate the Johnson Controls Verasys Zoning RTU (rooftop unit on the Verasys system bus)?

Start with MV 70101 UNIT-EN (Unit enable); MV 70001 OCC-MODE (Occupancy mode); AV 70023 DAT-SP (Discharge air temperature setpoint); AV 70211 DUCT-P-SP (Duct static pressure setpoint); AV 70203 DA-T (Discharge air temperature); AV 70200 RAT (Return air temperature); AV 70201 OAT (Outdoor air temperature); MV 70207 FAN-STS (Supply fan status); MV 70005 SYS-MODE (System mode); MV 70102 SAT-SNSR-FAULT (Supply air sensor fault).

How do I check these points on the real Verasys Zoning RTU (rooftop unit on the Verasys system bus)?

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.
