Trane чиллер коды ошибок

398 BAS Communication Lost. The BAS was setup as “installed” at the MP and the Comm 3 LLID lost communications with the BAS for 15 contiguous minutes after it had been established. Refer to Section on Setpoint Arbitration to determine how setpoints and operating modes may be effected by the comm loss. The chiller follows the value of the Tracer Default Run Command which can be previously written by Tracer and stored nonvolatilely by the MP (either use local or shutdown). 390 BAS Failed to Establish. The BAS was setup as “installed” and the BAS did not communicate with the MP within 15 minutes after power-up. Refer to Section on Setpoint Arbitration to determine how setpoints and operating modes may be effected. Note: The original requirement for this was 2 minutes, but was implemented at 15 minutes for RTAC 2E6 Check Clock. The real time clock had detected loss of its oscillator at some time in the past. This diagnostic can be effectively cleared only by writing a new value to the chiller’s time clock using the TechView or DynaView’s «set chiller time» functions. 8A Chilled Water Flow (Entering) The entering evaporator water temp fell below the leaving evaporator water temp. by more than 2°F for 100 °F-sec. For RTAC this diagnostic cannot reliably indicate loss of flow, but can warn of improper flow direction through the evaporator, misbound temperature sensors, or other system problems. 5EF Comm Loss: Chilled Water Flow Switch.

Trane troubleshooting codes –

Trane ac error code E1

Meaning: This indicates that there could be Indoor PCB problem

Trace AC Error code EC

Meaning: Refrigerant leak detection malfunction (Applies to Trane inverter air Conditioner Only)

Trace AC Error code P3 (indoor unit)

Meaning: Compressor current protection (The unit’s protection system has detected that the compressor could be drawing excessive current).

Recommended troubleshooting: Reset power to your system and check if the code disappears after this.

Trace AC Error code L3

Meaning: Outdoor fan 1 protection error.

Trane ac error code E3

Meaning: Error code E3 typically indicates low pressure protection.

Suggested action: Check that the system has been installed properly (pipes sized and also routed correctly). Also verify that the indoor & outdoor units have required clearances. If this does not help, check if refrigerant charge is enough (proper refrigerant charge needs to be maintained). If installation and refrigerant charge are correct, it could be that one/more EEVs is stuck. Check and repair.

Trane air conditioner error code 106

Meaning: Air handler might not be sensing power perhaps due to a tripped circuit breaker, power cutoff, failure switch, fried fuse, or board issue.

Suggested Troubleshooting: Use a multimeter to test the unit’s power supply system and repair as necessary.

Trane ac unit error codes – frequently asked questions (FAQs)

How do I reset my Trane air conditioner?

To have your Trane air conditioner reset (and clear an error code), all you need to do is simply reset the circuit breaker.

We suggest you wait a couple of minutes before restarting the unit.
What does E7 mean on Trane mini split?

The error code E7 typically points to a mode fault between indoor and outdoor unit. You can try turning power off (at the circuit breaker) to see if this will get rid of the issue.

What does H3 mean on Trane mini split?

Trane mini split error codes H3 may indicate compressor overheating protection (meaning that something could have caused the compressor to overheat (for example, a faulty condenser fan or Dust and debris build up on/around compressor).

Six types of modules are use and throughout this publication will be referred to by their abbreviations. Trane chillers are relied upon for both comfort and process applications in every corner of the world.

Trane products within the EcoWise portfolio are designed to help lower environmental impact with next-generation, low global warming potential (GWP) refrigerants and high-efficiency operation. Slave chiller MBB loses communication with master chiller MBB. Dual chiller control disabled. Wiring error , faulty wiring, failed master chiller MBB module, power loss at Master chiller.

Chiller runs as a stand-alone machine. Note any codes listed on the chiller (most of the newer chiller units have diagnostic codes or alarm codes to view).

Master and slave chiller have the same CCN address. Look up the reason in the equipment’s troubleshooting manual. Make sure the company can obtain that for you, even if you know the chiller.

EWP relay follows the AUTO mode of the chiller. Whenever the chiller has no diagnostics and is in the AUTO mode, regardless of where the auto command is coming from, the normally open relay is energized. When the chiller exits the AUTO mode, the relay is timed to open in an adjustable (using TU) to minutes. FAULT CODES FAULTY PROBES AND SENSORS.
