Carrier 48/50JC 04-06 Rooftop (SystemVu) BACnet points list

Updated 4 November 2026

Short answer

The 48/50JC small rooftops use the SystemVu unit control, which talks BACnet MS/TP (or CCN) on one RS-485 BMS port. The BACnet table holds about 720 analog, binary and multistate values covering setpoints, sensors, network inputs, runtimes, alerts and configuration.

This page lists 722 BACnet objects for the Carrier 48/50JC 04-06 Rooftop (SystemVu) — 487 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 48/50JC 04-06 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.

Object ID lookup: Carrier 48/50JC 04-06 Rooftop point IDs by name

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 48/50JC 04-06 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 48/50JC 04-06 Rooftop (SystemVu)

How many BACnet points does the Carrier 48/50JC 04-06 Rooftop (SystemVu) have?

This list has 722 BACnet objects: 426 analog values, 233 binary values, 63 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Carrier 48/50JC 04-06 Rooftop (SystemVu) BACnet points are writable?

487 of the 722 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 48/50JC 04-06 Rooftop (SystemVu) BACnet documentation?

The source is 48/50JC 04-06 Ultra High Efficiency Single Package Rooftop Units with SystemVu Controls Version 4.X, Controls, Start-Up, Operation and Troubleshooting (Appendix E: BACnet Points List) (48-50JC-4-6-05T), revision 2025-07, published free by Carrier at https://brandportal.carrier.com/asset/649f4f97-c004-4502-b520-8344d32ee884/48-50JC-4-6-05T.pdf.

What are the minimum BACnet points to integrate the Carrier 48/50JC 04-06 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 48/50JC 04-06 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 48/50JC 04-06 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 48/50JC 04-06 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 48/50JC 04-06 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.
