Carrier Unit Ventilator Open BACnet points list
Updated 4 November 2026
The Unit Vent (OPN-UV) is Carrier's i-Vu Open controller for unit ventilators. DIP switches select BACnet MS/TP (the default), BACnet ARC156, Modbus or N2, and a LonWorks option card is available. The points list has about 70 objects: setpoints, space, supply and outdoor temperatures, valve and damper outputs, enables, alarms and the 'system' points a BAS writes in place of local sensors.
This page lists 71 BACnet objects for the Carrier Unit Ventilator Open — 32 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 Unit Ventilator Open
Set the Unit Vent for BACnet MS/TP with its DIP switches and rotary address. Disable the local Occupancy Schedules so the BAS can command occupancy through keypad_ovrde, then write setpoints directly. Space temperature, CO2, OAT and changeover water temperature from the BMS go into the system_* points at priority 16 and have to be refreshed within each point's window.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| MV 1001 | keypad_ovrde | BAS occupancy command: occupied/unoccupied | Write |
| BV 9001 | shutdown | Network shutdown command | Write |
| AV 3001 | occ_cl_stpt | Occupied cooling setpoint | Write |

| BV 2008 | occ_status | Confirms occupied/unoccupied | Read |
| AV 2007 | space_temp | Space temperature the unit controls to | Read |
| AV 1008 | sa_temp | Supply air temperature | Read |
| BV 7008 | sfan_fail_alarm | Supply fan failure alarm | Read |
| BV 7037 | llt_alarm | Freezestat (low limit) alarm | Read |
Enable & remote start
The unit runs occupied 24/7 until a schedule or the BAS takes over. Disable Occupancy Schedules (Configuration > Unit Configuration) so the BAS can control it, then write BAS On/Off keypad_ovrde (MSV:1001): 1=Inactive, 2=Occupied, 3=Unoccupied. The system-point table says the occupancy control configuration must be set to 3 (BAS On/Off). Shutdown (BV:9001) stops the unit; Cool Enable (BV:1011) and Heat Enable (BV:1012) lock out cooling or heating.
Heartbeat & communication loss
No general heartbeat. Each system point is only used while it is refreshed within its window: space temperature 1 min / 5 min, CO2 5 min / 10 min, OAT and water temperature 5 min / 60 min.
Sensors & values from the BMS
Write system_spt (AV:1902), system_iaq (AV:1903), system_oat (AV:1901), system_water_temp (AV:1905) and system_stpt_adj (AV:1913) at BACnet priority 16, no more than once a minute. The controller clears a system point after processing it, so read the matching control point instead (space_temp, iaq, oa_temp, chgovr_mode) at least 30 s after the write.
Network setup
- MS/TP MAC address is set on the Tens and Ones rotary switches (1-99); read only at power-up.
- Device instance defaults to 16101xx (xx = rotary address); it can be changed with an Equipment Touch.
- Baud on DIP switches 1-2 (9600/19.2k/38.4k/76.8k, 76.8k default); DIP 3 and 4 both Off for BACnet MS/TP; 8N1.
- Max Masters defaults to 127 and Max Info Frames to 10 (Equipment Touch). The controller counts as a full load on the MS/TP bus.
Watch out for
- System points must be written at priority 16; writes at any other priority are ignored.
- Never write a system point more than once per minute.
- Only controllers set as MS/TP masters answer Who-Is.
- Demand level points (cool_demand_level, heat_demand_level) are read-only in this list, although the guide says the unit accepts three demand levels from the network.

Integration notes
- System points (system_spt, system_iaq, system_oat, system_stpt_adj, system_water_temp) must be written at BACnet priority 16 and no more than once a minute; -999 means no network value.
- The guide's general system-point table also lists system_rh (AV:1904), system_oaq (AV:1908), oae (BV:1901), press_override (BV:1906) and fire_shutdown (BV:1907). They are not in the Unit Vent points list, so they are left out here.
- Four rows are printed with the display name 'Setpoint'; the descriptions here say which setpoint each object name is.
- System Mode (run_status) prints state 12 twice (IAQ Override and Pre-occ Purge); kept as printed.
- Defaults in the points list differ from the sequence text for the fan delays (Fan Off Delay 90 s vs 120 s, Fan On Delay 10 s vs 30 s); check on the controller.
- Each point also has a Modbus register in the same table (some later rows have none); only the BACnet side is captured here.
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 Unit Ventilator Open and exports what it actually has to Excel — free. New to BACnet?

Questions about the Carrier Unit Ventilator Open
How many BACnet points does the Carrier Unit Ventilator Open have?
This list has 71 BACnet objects: 39 analog values, 27 binary values, 5 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier Unit Ventilator Open BACnet points are writable?
32 of the 71 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 Unit Ventilator Open BACnet documentation?
The source is Unit Ventilator Integration Guide (Appendix A: Unit Vent Network Points List) (11-808-513-01), revision 2022-08-02, published free by Carrier at https://www.shareddocs.com/hvac/docs/1000/Public/0D/11-808-513-01.pdf.
What are the minimum BACnet points to integrate the Carrier Unit Ventilator Open?
Start with MV 1001 keypad_ovrde (BAS occupancy command: occupied/unoccupied); BV 9001 shutdown (Network shutdown command); AV 3001 occ_cl_stpt (Occupied cooling setpoint); AV 3002 occ_ht_stpt (Occupied heating setpoint); MV 2002 run_status (Current system mode); BV 2008 occ_status (Confirms occupied/unoccupied); AV 2007 space_temp (Space temperature the unit controls to); AV 1008 sa_temp (Supply air temperature); BV 7008 sfan_fail_alarm (Supply fan failure alarm); BV 7037 llt_alarm (Freezestat (low limit) alarm).
How do I enable BMS control of the Carrier Unit Ventilator Open?
The unit runs occupied 24/7 until a schedule or the BAS takes over. Disable Occupancy Schedules (Configuration > Unit Configuration) so the BAS can control it, then write BAS On/Off keypad_ovrde (MSV:1001): 1=Inactive, 2=Occupied, 3=Unoccupied. The system-point table says the occupancy control configuration must be set to 3 (BAS On/Off). Shutdown (BV:9001) stops the unit; Cool Enable (BV:1011) and Heat Enable (BV:1012) lock out cooling or heating.
Does the Carrier Unit Ventilator Open need a BACnet heartbeat or have a communication timeout?
No general heartbeat. Each system point is only used while it is refreshed within its window: space temperature 1 min / 5 min, CO2 5 min / 10 min, OAT and water temperature 5 min / 60 min.
Can the BMS supply sensor values to the Carrier Unit Ventilator Open?
Write system_spt (AV:1902), system_iaq (AV:1903), system_oat (AV:1901), system_water_temp (AV:1905) and system_stpt_adj (AV:1913) at BACnet priority 16, no more than once a minute. The controller clears a system point after processing it, so read the matching control point instead (space_temp, iaq, oa_temp, chgovr_mode) at least 30 s after the write.
How do I check these points on the real Unit Ventilator Open?
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.
