Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP) BACnet points list

Updated 6 November 2026

Short answer

The TEC2647Z-3 is the zone controller of the Johnson Controls TEC zoning system for constant volume, pressure-dependent rooftop units. It modulates the zone damper, can drive analog or on/off reheat, and sends weighted heating and cooling demand to its rooftop controller over BACnet MS/TP. A supervisory controller can monitor it, schedule each zone, or take full control, depending on Cfg Network Handle.

BMS integration notes: Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)

Integration in brief

Give each zone controller and rooftop controller a unique MS/TP address, add them to the supervisory controller, then choose the network handle. With Default Zone Handle the supervisor only monitors; with 2 it can schedule each zone through GUI Occupancy (MV 9); with 3 it takes full control.

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

Cfg Network Handle (MV 7) sets how much control the supervisory controller has: 1 = Default Zone Handle (monitor only, zones follow the rooftop schedule), 2 = Default Minus Occupancy (each zone can be scheduled through GUI Occupancy, MV 9), 3 = Full Release (the supervisor takes full control). The handle can only be written from the supervisory controller, not the zone menu.

Sensors & values from the BMS

To feed room temperature from the BMS, set GUI Room Temp Override (BV 10) to Override and write GUI Room Temperature (AV 21). GUI Outdoor Temperature (AV 22) is writable.

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 TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)

How many BACnet points does the Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP) have?

This list has 51 BACnet objects: 1 analog input, 25 analog values, 2 binary inputs, 12 binary values, 11 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP) BACnet points are writable?

32 of the 51 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 TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP) BACnet documentation?

The source is TEC Zoning Control System for Stand-Alone and BACnet MS/TP Networked Applications Technical Bulletin (TEC2647Z-3, TEC2647Z-3+PIR, TEC2664Z-3) (LIT-12011682), revision 2011-05-13, published free by Johnson Controls at https://docs.johnsoncontrols.com/bas/api/khub/documents/y0yBSZRkp~9t9PGRQ94OSw/content.

What are the minimum BACnet points to integrate the Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)?

Start with MV 9 GUI Occupancy (Occupancy command (needs network handle 2 or 3)); MV 7 Cfg Network Handle (1 monitor only, 2 zone occupancy, 3 full release); AV 11 GUI Occupied Heat Spt (Occupied heating setpoint, °F); AV 12 GUI Occupied Cool Spt (Occupied cooling setpoint, °F); MV 11 GUI Effective Occupancy (Occupancy in effect); AV 21 GUI Room Temperature (Zone temperature, °F); AI 1 GUI Damper Position (Zone damper position, %); AV 19 GUI PI Heat Weighted Demand (Heating demand sent to the rooftop, %); AV 20 GUI PI Cool Weighted Demand (Cooling demand sent to the rooftop, %).

How do I enable BMS control of the Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)?

Cfg Network Handle (MV 7) sets how much control the supervisory controller has: 1 = Default Zone Handle (monitor only, zones follow the rooftop schedule), 2 = Default Minus Occupancy (each zone can be scheduled through GUI Occupancy, MV 9), 3 = Full Release (the supervisor takes full control). The handle can only be written from the supervisory controller, not the zone menu.

Can the BMS supply sensor values to the Johnson Controls TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)?

To feed room temperature from the BMS, set GUI Room Temp Override (BV 10) to Override and write GUI Room Temperature (AV 21). GUI Outdoor Temperature (AV 22) is writable.

How do I check these points on the real TEC2647Z-3 / TEC2647Z-3+PIR Zone Controller (TEC Zoning System, BACnet MS/TP)?

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.
