Trane

BACnetModbusREST

Trane builds commercial chillers, rooftop units, and the Tracer building-automation stack widely used in US institutional and commercial buildings. HVAC API's Trane integration is in beta: temperature and setpoint reads are stable; deeper Tracer telemetry is rolling out per device family.

Fault codes & error codes

12 codes documented for Trane. Confirm against your model's service manual — some codes vary between product lines (VRV vs. Sky Air vs. residential split, etc.).

Code	Category	Meaning	Suggested action	Severity	Help
12	Rooftop Unit	Inducer failed to prove — draft pressure faultAsk AI to troubleshoot →	Check inducer motor, pressure-prover tubing, and combustion air path.	critical	Ask AI →
15	Rooftop Unit	Ignition lockout — flame not establishedAsk AI to troubleshoot →	Verify gas pressure, spark ignitor gap, and flame-sensor microamp signal.	critical	Ask AI →
2	Rooftop Unit	High-pressure cutout tripAsk AI to troubleshoot →	Check condenser coil cleanliness, refrigerant overcharge, and HPS switch.	critical	Ask AI →
24	Chiller	Chilled-water low-temperature cutoutAsk AI to troubleshoot →	Verify leaving chilled-water temperature setpoint and antifreeze mix.	critical	Ask AI →
3	Rooftop Unit	Low-pressure cutout tripAsk AI to troubleshoot →	Check refrigerant charge and filter-drier; inspect LPS switch continuity.	critical	Ask AI →
4	Rooftop Unit	Compressor thermal overload openAsk AI to troubleshoot →	Allow cool-down; verify refrigerant charge and condenser airflow before restart.	critical	Ask AI →
10	Rooftop Unit	Evaporator coil freeze thermostat openAsk AI to troubleshoot →	Check airflow, return filter, and refrigerant charge; confirm freeze-stat setpoint.	warning	Ask AI →
105	Controller	Tracer SC communication error with field deviceAsk AI to troubleshoot →	Check LonTalk or BACnet wiring to the affected device; verify device address.	warning	Ask AI →
31	Chiller	Oil sump low temperature cutoutAsk AI to troubleshoot →	Check crankcase heater operation before next compressor start.	warning	Ask AI →
7	Rooftop Unit	Supply-air temperature sensor open or shortedAsk AI to troubleshoot →	Check SAT sensor resistance and harness connector at the RTM board.	warning	Ask AI →
8	Rooftop Unit	Outdoor-air temperature sensor open or shortedAsk AI to troubleshoot →	Check OAT sensor resistance and connector at the RTM board.	warning	Ask AI →
6	Rooftop Unit	Low-ambient lockout activeAsk AI to troubleshoot →	Unit locked out below minimum outdoor-air temperature; no action needed unless condition is incorrect.	info	Ask AI →
