Carrier VVT Zone II BACnet points list
Updated 4 November 2026
The VVT Zone II is Carrier's zone damper controller for VVT systems. It talks BACnet MS/TP (9600 to 76.8 kbps) or BACnet ARC156 on its BACnet port, with the address set on two rotary switches. Zones normally exchange data with their VVT Master and air source through Carrier linkage; a third-party BMS reads and writes the points below. Points cover setpoints, space and supply temperatures, damper position, occupancy, terminal mode and alarms.
This page lists 62 BACnet objects for the Carrier VVT Zone II — 23 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Carrier’s own free documentation, linked below.

BMS integration notes: Carrier VVT Zone II
Give the controller a unique MS/TP address on the rotary switches (the factory 00 must be changed) and match the network baud. To run occupancy from a third-party BMS, disable Occupancy Schedules and write BAS On/Off (keypad_ovrde). Write setpoints directly; send a network space temperature to system_spt if the zone has no local sensor.
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
BAS On/Off (keypad_ovrde, MSV:1001) gives a third-party BMS control of occupancy: 1 = Inactive, 2 = Occupied, 3 = Unoccupied. Occupancy Schedules must be set to Disable for it to work, and setting Occupied or Unoccupied turns Optimal Start off. Shutdown (BV:9001) stops the zone. Heat Enable (BV:1012) locks out zone heating.
Heartbeat & communication loss
No general heartbeat. A slave zone raises the Airside Linkage alarm (air_linkage_fail) if it gets no linkage data for 5 minutes.
Sensors & values from the BMS
A network space temperature must be written to system_spt (AV:1902) every 1 to 5 minutes or on a 0.1 °F change. Network RH, CO2, OAT and setpoint adjust go to system_rh, system_iaq, system_oat and system_stpt_adj. -999 means no network value. If no valid space temperature is available the zone raises the Space Temp Sensor alarm and stops local heating and cooling.
Network setup
- MS/TP address is set on the Tens and Ones rotary switches; the factory 00 must be changed. The controller reads the address at power-up.
- MS/TP runs at 9600, 19.2k, 38.4k or 76.8 kbps (DIP switches 1-2); ARC156 runs at 156 kbps via the ARC156/MS/TP jumper.
- A VVT Master can take up to 32 slave zones; an MS/TP network is limited to 60 controllers. Linked controllers on one MS/TP network must be addressed in sequence with the master at the highest address.
Watch out for
- A network schedule downloaded from i-Vu overwrites a local schedule.
- Air Source points read nothing on a stand-alone zone (no linkage).
- Several configuration rows in the guide have no object ID and cannot be read over BACnet.

Integration notes
- The points list also prints 11 rows with no BACnet object ID (the damper min/max positions, lux_bn, min_stpt_sep, occ_spt_alrm_hyst, dcv_enable, rh_enable). They are left out here.
- Space Temp Source (spt_status, MSV:2003) is split across a page break in the guide; its states are joined from both pages.
- System points (system_spt, system_rh, system_iaq, system_oat, system_stpt_adj) default to -999, meaning no network value.
- Air Source points (link_*) and Airside Linkage Status only carry data when the zone is linked to a Carrier air source.
- Units are shown in imperial as printed; '°^F' setpoint offsets are written here as delta °F.
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 VVT Zone II and exports what it actually has to Excel — free. New to BACnet?

Questions about the Carrier VVT Zone II
How many BACnet points does the Carrier VVT Zone II have?
This list has 62 BACnet objects: 35 analog values, 1 binary input, 19 binary values, 7 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier VVT Zone II BACnet points are writable?
23 of the 62 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 Carrier VVT Zone II BACnet documentation?
The source is VVT Zone II Controller Installation and Start-up Guide (Appendix D: BACnet points list) (11-808-603-01), revision 2025-11-12, published free by Carrier at https://www.shareddocs.com/hvac/docs/1000/Public/0A/11-808-603-01.pdf.
What are the minimum BACnet points to integrate the Carrier VVT Zone II?
Start with MV 1001 keypad_ovrde (BAS occupancy command: 2 = occupied, 3 = unoccupied); BV 9001 shutdown (Network shutdown command); AV 3001 occ_cl_stpt (Occupied cooling setpoint); AV 3002 occ_ht_stpt (Occupied heating setpoint); MV 2006 terminal_status (Current zone mode (heating, cooling, vent...)); BV 2008 occ_status (Confirms occupied/unoccupied); AV 2007 space_temp (Space temperature the zone controls to); AV 1013 dpr_pos (Zone damper position, %); BV 7001 spt_fail (No valid space temperature; local heat/cool off); BV 7030 air_linkage_fail (No linkage data from the air source for 5 min).
How do I enable BMS control of the Carrier VVT Zone II?
BAS On/Off (keypad_ovrde, MSV:1001) gives a third-party BMS control of occupancy: 1 = Inactive, 2 = Occupied, 3 = Unoccupied. Occupancy Schedules must be set to Disable for it to work, and setting Occupied or Unoccupied turns Optimal Start off. Shutdown (BV:9001) stops the zone. Heat Enable (BV:1012) locks out zone heating.
Does the Carrier VVT Zone II need a BACnet heartbeat or have a communication timeout?
No general heartbeat. A slave zone raises the Airside Linkage alarm (air_linkage_fail) if it gets no linkage data for 5 minutes.
Can the BMS supply sensor values to the Carrier VVT Zone II?
A network space temperature must be written to system_spt (AV:1902) every 1 to 5 minutes or on a 0.1 °F change. Network RH, CO2, OAT and setpoint adjust go to system_rh, system_iaq, system_oat and system_stpt_adj. -999 means no network value. If no valid space temperature is available the zone raises the Space Temp Sensor alarm and stops local heating and cooling.
How do I check these points on the real VVT Zone II?
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.
