Johnson Controls Verasys Zone Equipment Controller (ZEC) BACnet points list

Updated 12 November 2026

Short answer

The Zone Equipment Controller runs one zone of a Verasys zoning system (zone damper or VAV box, optional reheat). Through the SBH it exposes 57 objects in the 90,000 range: zone and discharge temperatures, occupied/unoccupied/standby setpoints, airflow limits, damper limits, DCV settings, enables, occupancy mode and zone vote.

This page lists 57 BACnet objects for the Johnson Controls Verasys Zone Equipment Controller (ZEC) — 38 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 Zone Equipment Controller (ZEC)

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 Zone Equipment Controller (ZEC) and exports what it actually has to Excel — free.

Questions about the Johnson Controls Verasys Zone Equipment Controller (ZEC)

How many BACnet points does the Johnson Controls Verasys Zone Equipment Controller (ZEC) have?

This list has 57 BACnet objects: 37 analog values, 20 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls Verasys Zone Equipment Controller (ZEC) BACnet points are writable?

38 of the 57 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 Zone Equipment Controller (ZEC) 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 Zone Equipment Controller (ZEC)?

Start with MV 90032 UNIT-EN (Unit enable); MV 90037 OCC-MODE (Occupancy mode); AV 90006 CLGOCC-SP (Occupied cooling setpoint); AV 90007 HTGOCC-SP (Occupied heating setpoint); AV 90000 ZN-T (Zone temperature); AV 90051 FLOW (Airflow); AV 90052 FLOW-SP (Airflow setpoint); AV 90003 DA-T (Discharge air temperature); MV 90062 HTGCLG-MODE (Heating/cooling mode); MV 90060 ZN-VOTE (Zone vote).

How do I check these points on the real Verasys Zone Equipment Controller (ZEC)?

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.
