The rooftop points a BMS uses
Trane's names tell you the access: BAS, Request, Command and AV/BV/MV Setpoint points are written; Status, Active, Local and Input points are read. Which points exist depends on how the unit is configured — a dual-setpoint sensor, an economizer, a second compressor.
| Object | Object name | Access | What it is |
|---|---|---|---|
| AV-10127 | Space Temperature Setpoint BAS | W | The space setpoint from the BMS (single-setpoint control). Write at a priority stronger than 14 |
| AV-10159 / AV-10160 | Occupied Cooling / Heating Setpoint BAS | W | Separate occupied cooling and heating setpoints (dual-setpoint control) |
| AV-10114 | Space Temperature BAS | W | Space temperature from the BMS, when the unit has no sensor of its own |
| AV-10113 | Outdoor Air Temperature BAS | W | Outdoor air temperature from the BMS |
| MV-10106 | Occupancy Request | W | 1 Occupied, 2 Unoccupied, 3 Occupied Bypass, 4 Occupied Standby, 5 Auto |
| MV-10104 | Heat Cool Mode Request | W | 1 Auto, 2 Heat, 4 Cool, 7 Off, 10 Fan Only and others |
| AV-10139 | Cooling Capacity Enable | W | Cooling capacity allowed, % — the demand limit for cooling |
| MV-11100 | Arbitration Method Request | W | 1 Enable External/BAS Control, 2 Standalone Control |
| BV-10110 | Reset Diagnostic | W | Resets diagnostics that may be reset |
| AV-11178 | Space Temperature Active | R | The space temperature the unit controls to |
| AV-11181 | Space Temperature Setpoint Active | R | The setpoint actually in use, after arbitration — compare it with what you wrote |
| AV-11128 / AV-11129 | Space Temp Cooling / Heating Setpoint Status | R | The cooling and heating setpoints in use |
| AI-10124 | Discharge Air Temperature Local | R | Discharge air temperature |
| AI-10118 | Outdoor Air Temperature Active | R | Outdoor air temperature in use |
| AI-10101 | Cooling Capacity Status | R | Cooling capacity running, % |
| MI-10101 | Heat Cool Mode Status | R | The mode it is in (same list as the request, plus Morning Warm-up, Economizer, Dehumidify…) |
| MV-11123 | Occupancy Status | R | The occupancy in force |
| BI-10226 / AV-11163 | Supply Fan Status / Supply Fan Speed Status | R | Supply fan on, and its estimated speed % |
| BI-11100 / BI-11103 | Compressor 1 / 2 Command Status | R | Compressor outputs |
| BI-10219 | Economizer Airside Status | R | Airside economizing active |
| BV-11100 | Alarm Indicator Status | R | The controller's alarm output |
| BV-11144 | Diagnostic: Filter Change Required | R | Dirty filter (with a clogged-filter switch installed); every diagnostic has its own point |
| AV-11169 / AV-11183 | Run Time - Compressor 1 (Hours) / Starts - Compressor 1 | R | Compressor run hours and starts |
The complete list — about 640 objects with their Modbus registers, availability conditions and defaults — is Trane's BAS-PTS001C-EN for Precedent and Axiom units; Voyager 3 has its own in BAS-SVP066B-EN, with the same object numbers for the points above.
