Trane chiller fault codes

Section 1: Diagnostic Reference Tables. TRANE Diagnostic Fault Codes. Another common light to be aware of on your Trane furnace is a light that flashes very rapidly.

This code is the exact opposite of the slow flashing light code , and means that your Trane furnace is turned on and that it is presently calling for heat. This code usually means a problem only when the furnace is constantly calling for heat and not responding to your thermostat’s signals. Connecting to AC Mains Table 4.

Motor connection † Earth (ground) the cable in accordance with the instructions provided † All frequency converters may be used with an isolated input source as well as with earth (ground) reference power lines. 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.

It means the equipment reporting does not match the equipment originally discovered. Access the Summary Table in the Diagnostic tab to get a list of discovered communicating components and their status. Thanks for fielding my question. They system will not cool or heat. However, it will heat from the coils if I call for emergency heat.

My fault codes are as follows: From AFC Board: red From EVC Board: red First, According to the manual, the red on the AFC board simply tells me to research the red from the EVC board. I have Trane chiller CGACC804RLNJJsecond stage compressor circuit drops off line, has no fault on controler, compressor safty circuit not trippe manual reset required. Determine which fault the chiller is off on by the red indicator light on the left side of the controller.
