Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps BACnet points list
Updated 7 November 2026
Short answer
The SMS is a plant controller for up to four modular R-290 air-source heat pumps; it talks to the heat pumps over BACnet IP and offers BACnet IP and Modbus TCP to the BMS through the Ethernet switch in its cabinet. The object list has 315 objects grouped by function: general system commands and status, schedules, two heating/cooling zones, customer and DHW pump sets, the heat pump manager, and one block per heat pump.
This page lists 315 BACnet objects for the Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps — 80 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 System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps
Integration in brief
Connect the BMS to the Ethernet switch in the SMS cabinet. Put the system in Auto operating type with the front button, then drive it with the On/Off input command (MV 502) and the heating/cooling selection (MV 521), adjust zone setpoints, and read system status, temperatures, heat pump status and the synthesis alarm.
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.

| MV 1052 | ch1_status_1 | Heat pump 1 status (running, failure, no comm...) | Read |
| BV 548 | alarm_synthesis_5 | General (synthesis) alarm | Read |
Enable & remote start
The system follows the On/Off input command only in the Auto operating type selected with the SMS front button (AV 501 reports it). In Auto the command can be Off, On or Based on Schedule. The network emergency stop shuts the system down in any operating type.
Sensors & values from the BMS
Zone relative humidity for dew point calculation (AV 264) can be written by the BMS when floor sensors are used.
Network setup
- The SMS has five Ethernet ports for the heat pumps (BACnet IP) and the BMS (BACnet IP, Modbus TCP).
- Each heat pump must be set to Network control mode, or the SMS raises a 'not in network mode' alarm and drops it from the sequence.
Watch out for
- Maintenance-mode BVs (e.g. BV 126-129) stop a heat pump or pump when set; do not leave them active.
- Several points are labelled 'Zone n°1 or No Zone'; on a single-zone plant only the zone 1 points apply.

Integration notes
- Source is the BACnet object spreadsheet (SMS_OPT275A_BACNET_COM) inside Carrier's "BMS Protocols" zip for option 275A; the zip's Modbus files are not used.
- State texts are taken from the description cells (e.g. 1 = OFF / 2 = ON / 3 = Based on Schedule); long descriptions are shortened.
- The heat pump n°1 to n°4 blocks are all printed in the sheet; blocks for heat pumps that are not installed stay unused.
- Zone 2, DHW, boiler and pump-set points only apply when those parts of the plant are configured.
- Integration notes also draw on the SMS IOM control manual (Carrier Europe document 10991, 12-2025).
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 System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps 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 System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps
How many BACnet points does the Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps have?
This list has 315 BACnet objects: 144 analog values, 137 binary values, 34 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps BACnet points are writable?
80 of the 315 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 System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps BACnet documentation?
The source is SMS OPT275A BMS Protocols (BACnet object list SMS_OPT275A_BACNET_COM.xlsx) (EN_SMS_OPT275A_BMS_Protocols), published free by Carrier at https://brandportal.carrier.com/asset/081c4b3d-90a3-48e5-a641-f9ee46d25993/EN_SMS_OPT275A_BMS_Protocols.zip.
What are the minimum BACnet points to integrate the Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps?
Start with MV 502 on_off_command_5 (On/off command: 1=Off, 2=On, 3=Based on schedule); MV 521 manual_hc_sel_5 (Heating/cooling selection (3 = auto changeover on OAT)); MV 200 z1_setpoint_input_2 (Zone 1 setpoint mode: Eco, Comfort or Auto); AV 226 z1_heat_comfort_setpoint_2 (Zone 1 comfort heating water setpoint); AV 216 z1_cool_comfort_setpoint_2 (Zone 1 comfort cooling water setpoint); BV 505 emergency_shutdown_5 (Emergency shutdown signal from the BMS); AV 501 manager_control_mode_5 (Front panel button: 1=Off, 2=On, 3=Auto); AV 1032 lwt_evap_temp_1 (Common leaving water temperature); MV 1052 ch1_status_1 (Heat pump 1 status (running, failure, no comm...)); BV 548 alarm_synthesis_5 (General (synthesis) alarm).
How do I enable BMS control of the Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps?
The system follows the On/Off input command only in the Auto operating type selected with the SMS front button (AV 501 reports it). In Auto the command can be Off, On or Based on Schedule. The network emergency stop shuts the system down in any operating type.
Can the BMS supply sensor values to the Carrier System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps?
Zone relative humidity for dew point calculation (AV 264) can be written by the BMS when floor sensors are used.
How do I check these points on the real System Management Sequencer (SMS) Option 275A for modular R-290 air-source heat pumps?
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.
