Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) BACnet points list
Updated 12 November 2026
This is the ComfortLink 6.x generation of the WeatherExpert 48/50N. BACnet MS/TP comes from a UPC Open controller in its own enclosure below the main control box, which reads the ComfortLink board over CCN. The list has 351 objects (AVs, BVs and one multistate value): occupancy, supply air and static pressure setpoints, air temperatures, pressures and flows, up to four compressors per circuit, heat, economizer, Motormaster and VFD values, Humidi-MiZer, airside linkage values, thermostat inputs, alarm flags and spare user values.
This page lists 351 BACnet objects for the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) — 129 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 WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)
The BMS talks BACnet MS/TP to the UPC Open, which reads and writes the ComfortLink control over CCN. Clear Local Machine Disable, set the CCN schedule number for the occupancy source you want, then write occupancy and (for VAV) the supply air and duct static setpoints; read HVAC mode, temperatures, fan speed and alarm state. Values the BMS feeds in are forces that clear if not refreshed.
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 |
|---|---|---|---|
| BV 2008 | occ_status_1 | Occupied? (0 = no, 1 = yes); writable | Write |
| AV 3007 | sa_temp_stpt_1 | Supply air setpoint (VAV units) | Write |
| AV 3050 | sa_static_stpt_1 | Duct static pressure setpoint (VAV units) | Write |
| AV 1022 | hvac_mode_1 | HVAC mode as a number | Read |
| AV 2050 | sf_vfd_output_1 | Supply fan VFD speed, % | Read |
| AV 43 | ctrltemp_1 | Control temperature (RAT, SPT or zone) | Read |
| AV 10 | sat_1 | Supply air temperature leaving the fan | Read |
| BV 9 | alm_1 | Unit alarm state | Read |
| BV 105 | comm_lost_alm_1 | UPC lost CCN communication with the unit | Read |
Enable & remote start
The unit ships with Local Machine Disable (Service Test > STOP, BV 59 unitstop_1) set to Yes; set it to No before the unit runs. Occupancy follows the ComfortLink CCN schedule number (SCH.N): 0 = always occupied, 1 = local schedule, 65-99 = a CCN schedule. The points list makes Occupied? (BV 2008) writable, but the manual does not describe how a write interacts with SCH.N; test it on site.
Heartbeat & communication loss
The manual says forces at CCN priority 7 clear unless rewritten in time: outside air temperature, outside RH, outside air quality and static pressure reset after 30 minutes, return air and space temperature after 3 minutes.
Sensors & values from the BMS
Space Temperature (AV 137), Return Air Temperature (AV 135), Outside Air Temperature (AV 1003), Outside Air RH (AV 119), IAQ (AV 1009) and OAQ (AV 113) are writable. Refresh them within the force timeouts (3 min for space and return temperature, 30 min for outdoor values).
Network setup
- Set the MAC address on the UPC Open's Tens and Ones rotary switches; the controller reads switches, DIP switches and jumpers only at power-up.
- Device instance = network number (default 16101) followed by the MAC address, e.g. MAC 20 gives 1610120.
- BAS port: DS3 enable, DS4 E1-485, DS5-DS8 set to MSTP; baud on DS1-DS2 (9600, 19.2k, 38.4k or 76.8k, Carrier default 76.8k); 8N1 fixed. EIA-485 jumpers to EIA-485 and 2W.
- Fit a BT485 terminator on the first and last controller of the MS/TP segment.
- The UPC Open and the ComfortLink board must use the same CCN element and bus numbers (factory 1 and 0).
Watch out for
- Points depend on unit options (heat type, economizer, Humidi-MiZer, VFDs, airflow monitoring, controls expansion boards); objects for options not fitted carry no useful data.
- Thermostat inputs (Y1, Y2, W1, W2, G) and switch inputs are writable BVs (CCN forces).
- The user-defined analog and binary values are spare objects with no unit function.

Integration notes
- Form 48/50N-6T (4-18) for ComfortLink 6.x units. All 164 objects of the ComfortLink 11.x list (48-50N-8T) are also here; this older list adds 187 more, mostly individual alarm flags, linkage values and service data.
- Object names end in _1. Descriptions are the printed point descriptions, with the CCN point name added where two rows share a description.
- Econ3 Act. Unavailable? is printed as BV60 (no colon) and kept as BV 60. The Linkage Collector row (link_collector_1) prints no object ID and is left out. Cir B Discharge Pressure (AV 1605) is printed twice and kept once.
- Air Source Mode is printed as MSV:2005 (mapped as MV 2005).
- Units printed as dF are shown as °F; °^F as Δ°F (temperature differences). Ranges and defaults are left out.
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 WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) 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 WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)
How many BACnet points does the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) have?
This list has 351 BACnet objects: 227 analog values, 123 binary values, 1 multi-state value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) BACnet points are writable?
129 of the 351 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 WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) BACnet documentation?
The source is WeatherExpert 48/50N2,N3,N4,N5,N6,N7,N8,N9 Packaged Rooftop Cooling Units with Gas Heat, Optional Electric Heat, or Hydronic Heat and ComfortLink Controls Version 6.x - Controls, Start-Up, Operation, Service and Troubleshooting (Appendix F: BACnet Communication Option, Network Points List) (48/50N-6T), revision 4-18, published free by Carrier at https://www.shareddocs.com/hvac/docs/1005/Public/0C/48_50N-6T.pdf.
What are the minimum BACnet points to integrate the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)?
Start with BV 2008 occ_status_1 (Occupied? (0 = no, 1 = yes); writable); AV 3007 sa_temp_stpt_1 (Supply air setpoint (VAV units)); AV 3050 sa_static_stpt_1 (Duct static pressure setpoint (VAV units)); AV 1022 hvac_mode_1 (HVAC mode as a number); AV 2050 sf_vfd_output_1 (Supply fan VFD speed, %); AV 43 ctrltemp_1 (Control temperature (RAT, SPT or zone)); AV 10 sat_1 (Supply air temperature leaving the fan); BV 9 alm_1 (Unit alarm state); BV 105 comm_lost_alm_1 (UPC lost CCN communication with the unit).
How do I enable BMS control of the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)?
The unit ships with Local Machine Disable (Service Test > STOP, BV 59 unitstop_1) set to Yes; set it to No before the unit runs. Occupancy follows the ComfortLink CCN schedule number (SCH.N): 0 = always occupied, 1 = local schedule, 65-99 = a CCN schedule. The points list makes Occupied? (BV 2008) writable, but the manual does not describe how a write interacts with SCH.N; test it on site.
Does the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option) need a BACnet heartbeat or have a communication timeout?
The manual says forces at CCN priority 7 clear unless rewritten in time: outside air temperature, outside RH, outside air quality and static pressure reset after 30 minutes, return air and space temperature after 3 minutes.
Can the BMS supply sensor values to the Carrier WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)?
Space Temperature (AV 137), Return Air Temperature (AV 135), Outside Air Temperature (AV 1003), Outside Air RH (AV 119), IAQ (AV 1009) and OAQ (AV 113) are writable. Refresh them within the force timeouts (3 min for space and return temperature, 30 min for outdoor values).
How do I check these points on the real WeatherExpert 48/50N2-N9 Rooftop (ComfortLink 6.x, UPC Open BACnet option)?
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.
