Carrier 48/50LC 04-26 Rooftop (SystemVu) BACnet points list
Updated 4 November 2026
Short answer
SystemVu is the factory-installed unit control on Carrier's 48/50LC rooftops. It talks BACnet MS/TP (or CCN) on one RS-485 BMS port. The BACnet table holds about 790 analog, binary and multistate values: setpoints, sensor readings, network inputs, run hours and starts, alerts, and a large set of configuration values.
This page lists 787 BACnet objects for the Carrier 48/50LC 04-26 Rooftop (SystemVu) — 520 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 04-26 Rooftop (SystemVu)
Integration in brief
The SystemVu control has one RS-485 BMS port. Set BAS Protocol to BACnet on the unit display (Settings > Network Settings), set the MAC address and baud rate, power-cycle and connect to the MS/TP trunk. Run occupancy from a BACnet schedule or the BMS Occupancy Request point, write the occupied setpoints, and read the system mode, temperatures and the active fault count.
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
Set BAS Protocol Select to BACnet on the unit display (Settings > Network Settings > BAS Protocol; default None). With BACnet selected the local occupancy schedule is reset and scheduling comes from the BACnet side: a BACnet schedule, or the BMS Occupancy Request (MV 12; the display tables list Unocc, Occupied and Disabled). Unit Control Type (MV 2) decides whether the unit runs from thermostat inputs or a space sensor.
Heartbeat & communication loss
Network Input Timeout (AV 9089, default 30 min per the display tables) applies to the network input values. The guide does not say what the unit does when it expires, so keep any written network value refreshed well inside that time.
Sensors & values from the BMS
Writable network inputs exist for space temperature (Network Space Temp Value, AV 7006), outdoor air temperature (AV 7007), return air temperature (AV 7005), space RH (AV 376), outdoor RH (AV 7003), IAQ and OAQ CO2 (AV 7001, AV 7002) and OA cfm (AV 371). The guide doesn't explain how the unit picks a network value over a local sensor; check the sensor channel settings on the display. The 'BACnet device for ...' and 'Object instance for ...' AVs let the unit read a sensor from another BACnet device.
Network setup
- BACnet MS/TP only, on the single RS-485 BMS port that is also used for CCN. Defaults: MAC address 01, baud 76800 (BACNET BAUDRATE 4).
- i-Vu auto ID: with the auto ID scheme on, set the MAC and the device ID becomes the network number plus the MAC. With it off, set the MAC and write the device ID over BACnet; the controller keeps it.
- To set the device ID by hand, set BACnet ID to manual on the display and enter it there. The MAC range for each mode is in the guide's BACnet settings table.
- Power the controller down after changing the BACnet settings, then connect it to the MS/TP network.
Watch out for
- Instances are not sequential (AV 9089, BV 7048, MV 2002 and so on); map by instance, not by position in the table.
- Many configuration MVs and AVs are option codes or sensor channel numbers; read the current value and check the display before writing.
- The guide gives only a numeric range for MV 12 and the other multistates; confirm the state numbering on the unit before writing.
- BV 7048 shows the alarm relay; which alerts drive the relay is set under Unit Configurations > Alarm Relay.

Integration notes
- Taken from Appendix E of the guide (pp. 165-179: AV, BV and MSV tables). MSV objects are listed as MV.
- Each SystemVu rooftop guide prints a different object set; this one, for example, has the direct-drive IDF speed relay points (BV 446-448) that the others lack.
- The table also gives a CCN point name for most objects; only the BACnet side is captured here.
- Value ranges from the table are added to the descriptions in brackets. The BACnet table prints no multistate state texts; the display and CCN tables elsewhere in the guide list the options for many of them.
- The guide also lists about 14 string objects (software versions, model and serial numbers, device description), all with the ID String:0; they are left out because no usable instance is printed.
- Which objects exist depends on unit size, heat type and installed options (economizer, Humidi-MiZer, VFD fan, accessories). Many alert and fault flags (a_*, f_*) are printed as R/W and kept that way.
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 04-26 Rooftop (SystemVu) 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 04-26 Rooftop (SystemVu)
How many BACnet points does the Carrier 48/50LC 04-26 Rooftop (SystemVu) have?
This list has 787 BACnet objects: 456 analog values, 274 binary values, 57 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier 48/50LC 04-26 Rooftop (SystemVu) BACnet points are writable?
520 of the 787 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 04-26 Rooftop (SystemVu) BACnet documentation?
The source is 48/50LC 04-26 Single Package Rooftop Units with SystemVu Controls Version 7.X, Controls, Start-Up, Operation and Troubleshooting (Appendix E: BACnet Points List) (S-VU-LC-4-26-06T), revision 2024-02, published free by Carrier at https://brandportal.carrier.com/asset/4cca75f1-e40c-4439-aaee-26020fcf2db9/S-VU-LC-4-26-06T.pdf.
What are the minimum BACnet points to integrate the Carrier 48/50LC 04-26 Rooftop (SystemVu)?
Start with MV 12 bms_occ (Occupancy request from the BMS (unocc / occupied / disabled)); AV 288 ocsp (Occupied cooling setpoint); AV 289 ohsp (Occupied heating setpoint); BV 33 alarm_reset (Resets all current alarms); MV 2002 sys_mode (Current mode (off, cool, heat, vent, test)); AV 35 req_fan_spd (Indoor fan speed the control is calling for, %); AV 296 space_t (Space temperature); AV 1008 sa_temp (Supply air temperature); BV 7048 equip_alarm (Alarm output relay state); AV 335 num_active_faults (Count of active faults).
How do I enable BMS control of the Carrier 48/50LC 04-26 Rooftop (SystemVu)?
Set BAS Protocol Select to BACnet on the unit display (Settings > Network Settings > BAS Protocol; default None). With BACnet selected the local occupancy schedule is reset and scheduling comes from the BACnet side: a BACnet schedule, or the BMS Occupancy Request (MV 12; the display tables list Unocc, Occupied and Disabled). Unit Control Type (MV 2) decides whether the unit runs from thermostat inputs or a space sensor.
Does the Carrier 48/50LC 04-26 Rooftop (SystemVu) need a BACnet heartbeat or have a communication timeout?
Network Input Timeout (AV 9089, default 30 min per the display tables) applies to the network input values. The guide does not say what the unit does when it expires, so keep any written network value refreshed well inside that time.
Can the BMS supply sensor values to the Carrier 48/50LC 04-26 Rooftop (SystemVu)?
Writable network inputs exist for space temperature (Network Space Temp Value, AV 7006), outdoor air temperature (AV 7007), return air temperature (AV 7005), space RH (AV 376), outdoor RH (AV 7003), IAQ and OAQ CO2 (AV 7001, AV 7002) and OA cfm (AV 371). The guide doesn't explain how the unit picks a network value over a local sensor; check the sensor channel settings on the display. The 'BACnet device for ...' and 'Object instance for ...' AVs let the unit read a sensor from another BACnet device.
How do I check these points on the real 48/50LC 04-26 Rooftop (SystemVu)?
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.
