Johnson Controls VZC100 Verasys Zone Coordinator BACnet points list

Updated 12 November 2026

Short answer

The VZC100 coordinates a Verasys zoning system: it collects heating and cooling requests from the zones and resets the rooftop unit's discharge air and duct static pressure. Through the SBH it exposes 30 objects: changeover and reset settings, setpoints, enable and mode commands, request counts and the zoning system state.

This page lists 30 BACnet objects for the Johnson Controls VZC100 Verasys Zone Coordinator — 23 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 VZC100 Verasys Zone Coordinator

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 VZC100 Verasys Zone Coordinator and exports what it actually has to Excel — free. New to BACnet?

Questions about the Johnson Controls VZC100 Verasys Zone Coordinator

How many BACnet points does the Johnson Controls VZC100 Verasys Zone Coordinator have?

This list has 30 BACnet objects: 16 analog values, 14 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls VZC100 Verasys Zone Coordinator BACnet points are writable?

23 of the 30 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 VZC100 Verasys Zone Coordinator 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 VZC100 Verasys Zone Coordinator?

Start with MV 23475 UNIT_EN (Unit enable); MV 23476 CONTROL-MODE (Control mode); AV 23474 DAT-SP (Discharge air temperature setpoint); AV 23468 DUCT-P-SP (Duct static pressure setpoint); AV 23470 CLGOCC-SP (Occupied cooling setpoint); AV 23471 HTGOCC-SP (Occupied heating setpoint); AV 23488 TOT-CLG-REQ (Total cooling requests from zones); AV 23487 TOT-HEAT-REQ (Total heating requests from zones); MV 23492 ZN-SYS-STATE (Zoning system state).

How do I check these points on the real VZC100 Verasys Zone Coordinator?

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.
