If a Trane Chiller compressor generates more than three identical faults within an hour, it will be placed in the ‘Offline’ state, considered locked out, and will require a power-cycle to reset.
What happens when my Trane Thermafit TACW Chiller is in Alarm Avoidance?
When a Trane Chiller is in Alarm Avoidance mode, no immediate action may be needed, and the alarm can be deleted from the list. If the system is loading, it will stop loading. The system demand will be reduced by 0.5% per second until the demand reaches 10% or the compressors reach surge speed. If the alarm persists and compressors are at surge speed, the controller will enter ‘Stage-out’ state, turning off compressors every 2 minutes until only one remains operational. The chiller may be turned off, shutting down all compressors. The fault will automatically reset after a set time (default is 3 minutes), returning the system to ‘Idle’ state.
What to do if Trane Thermafit TACW fault cannot be reset automatically?
If a fault on your Trane Chiller cannot be reset automatically, the compressor state is set to 'Offline'. The compressor will require a hard reset (Power-Cycle) to reset the fault. After a successful power-cycle, the compressor should return to the 'Idle' state and be ready to start again.
