Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) BACnet points list
Updated 4 November 2026
The VAV-RTU Open is the factory controller on the 48/50LC B VAV rooftops. It runs as a BACnet MS/TP master, either as the air source for a Carrier VAV zoning system (Airside Linkage) or standalone under a third-party BMS. The points list has about 190 objects: sensor inputs, setpoints, supply-air and static-pressure control, service tests, runtimes and alarms.
This page lists 191 BACnet objects for the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) — 87 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 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open)
Set SW3 to BACnet MS/TP and the baud rate, set the address on SW1/SW2 and cycle power. For standalone use under a third-party BMS, command occupancy with BAS On / Off (MV 1001), write the occupied setpoints and the supply-air and static-pressure setpoints, and read the system mode, fan state, supply air temperature and alarms.
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, MV 1001) is the network occupancy input for third-party systems: 1 = Inactive (default), 2 = Occupied (occupied heating and cooling setpoints apply), 3 = Unoccupied (unoccupied setpoints apply). A BACnet schedule from i-Vu or the remote occupancy input can also set occupancy. Shutdown (BV 9001) is a writable shutdown point.
Sensors & values from the BMS
The System points take network values: System Space Temperature (AV 1902), System Space RH (AV 1904), System Space AQ (AV 1903), System Outdoor Air Temperature (AV 1901), System Outdoor AQ (AV 1908) and System Return Air Temperature (AV 1920). The table prints -999 as their default value. The guide gives no refresh time.
Network setup
- SW3 DIP switches set the protocol (BACnet MS/TP master) and baud rate (9600, 19200, 38400 or 76800); SW1 and SW2 set the MS/TP address (01-99). Cycle power after changing them.
- In a Carrier VAV system the zone controllers and the VAV-RTU Open are linked through a VAV Master zone controller, which must have the highest address on the MS/TP network.
- A Field Assistant laptop connects at the J12 local access port; the System Touch wall display connects to the MS/TP network.
Watch out for
- Economizer Exists (BV 99001) is set at the factory and is not field configurable.
- Several alarm BVs share a display name with the analog value they belong to (e.g. 'Compressor 1 Runtime' is both AV 2017 and BV 7014); go by the object name.
- The Service Test and Factory Test points (BV 81000-81008, BV 91001-91008, AV 91001-91002) drive outputs directly; leave them alone in normal operation.

Integration notes
- Taken from Appendix D, Table C 'VAV-RTU Open Protocol Maps' (pp. 49-52). MSV objects are listed as MV.
- Point display names are as printed; four setpoints are all named 'Setpoint' in the table, so the description says which one (from the BACnet object name).
- Default values printed in the table are added to the descriptions. Multistate state texts are taken from the units column where printed.
- The System Mode states are printed with '8=Shutdow'; kept as printed.
- A different controller from the SystemVu control used on the 48/50LC 04-26 units and from the RTU Open controller, which have their own lists.
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 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open)
How many BACnet points does the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) have?
This list has 191 BACnet objects: 6 analog inputs, 72 analog values, 5 binary inputs, 86 binary values, 22 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) BACnet points are writable?
87 of the 191 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 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open) BACnet documentation?
The source is 48/50LCB07-26 with VAV-RTU Open Controller, Controls, Start-Up, Operation and Troubleshooting (Appendix D: BACnet Points List) (48-50LCB-7-26-04T), revision 2022-05, published free by Carrier at https://brandportal.carrier.com/asset/1d59de26-3b17-4555-8d1e-6f6126a95717/48-50LCB-7-26-04T.pdf.
What are the minimum BACnet points to integrate the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open)?
Start with MV 1001 keypad_ovrde (BAS occupancy: 1=Inactive, 2=Occupied, 3=Unoccupied); AV 3001 occ_cl_stpt (Occupied cooling setpoint); AV 3002 occ_ht_stpt (Occupied heating setpoint); AV 3029 sat_cl_stpt (Supply air setpoint for cooling (default 53 °F)); AV 3030 sa_static_stpt (Duct static pressure setpoint); MV 2002 run_status (Current system mode); BV 2001 sfan (Supply fan relay on/off); AV 1008 sa_temp (Supply air temperature); AV 2028 static_press (Duct static pressure); BV 7024 safety_alarm (Safety chain alarm).
How do I enable BMS control of the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open)?
BAS On / Off (keypad_ovrde, MV 1001) is the network occupancy input for third-party systems: 1 = Inactive (default), 2 = Occupied (occupied heating and cooling setpoints apply), 3 = Unoccupied (unoccupied setpoints apply). A BACnet schedule from i-Vu or the remote occupancy input can also set occupancy. Shutdown (BV 9001) is a writable shutdown point.
Can the BMS supply sensor values to the Carrier 48/50LC B 07-26 VAV Rooftop (VAV-RTU Open)?
The System points take network values: System Space Temperature (AV 1902), System Space RH (AV 1904), System Space AQ (AV 1903), System Outdoor Air Temperature (AV 1901), System Outdoor AQ (AV 1908) and System Return Air Temperature (AV 1920). The table prints -999 as their default value. The guide gives no refresh time.
How do I check these points on the real 48/50LC B 07-26 VAV Rooftop (VAV-RTU 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.
