View Full Version : Costco Trane TCI Issues
05-24-2008, 10:57 AM
Hey everyone, I'm new to forum, I mostly do refrigeration , ice makers. Checked out a Costco AC the other day. It has Trane TCI3 boards in them. I never found the controller downstairs that runs them. (tracer, tracker? who knows). They have a computer in the office that was giving an alarm for compressor/ fan failure. The temps were OK in the spaces.
Looking at the units, I didn't see any current transducers, pressure transducers or any controls except for standard high, low pressure. Where do I get info on these Voyager units controls? The 5 units in alarm weren't running high pressures, low pressures and would bring on all stages in test. Also, how do I reset the alarms? Can I get software /hardware for my laptop to connect with the system?
I deal with Comtrol, CPC, Novar, controllers everyday but this is the first I've seen the HVAC version. Thanks for any help. Dexter

If they have a computer in the office with Summit on it then just use that. You can reset alarms, look at the units, etc..
You can buy tracer summit for your laptop, but for it to be a good investment i would think you would need lots of jobs out there that you look at with a Trane BCU. For you to buy it just for this one job would be a waste.
The Costco for the most part are a national account for trane. They have a single office that takes care of all the stores. Was that way last time i did one but maybe not ever store is under their control

Hey scrooloose, Thanks for reply. The manager told me you couldn't reset alarms with his computer until after midnight.(don't know why). If the software is high, forget it. These are occasional repairs. I still don't know what the alarm actually was or what control generated it. I'll still need some info on how the Voyager and TCI board interact. I'll probably need to get on the managers computer and play.

Well the TCI board just passes info to the summit system. Any alarms that is generated at the RTU is passed down to the BCU. So as far as what control generated it would be the actual RTU.
The comps might not have been locked out at the time you were there. You would have to check the alarm log and see if the units returned to normal after the trip. Cycling power or possibly even putting them in test will reset the alarms and let you run them.
The fan failure is a little dp that is mounted on the side of the fan housing. Only about the size of a quarter.
Post the model number of the unit and someone here can probably post a pdf for you.

Thanks for replies. The units I'm working on are Voyager YCD301c4lgba models. I've put my email in my profile in case anybody has any info on hand. We don't do a lot of Trane work so we don't get much factory support. If all the fails are coming from the unit, then I'll be able to find the problem with standard troubleshooting. Next time at the store I'll try to find out what hardware is there and play with the software.

Thanks for info on the Trane Voyager and Tracer setup. I still need all the help I can get but I'll be able to get the initial run of units up OK. If we get into the system more I'll buy the software for the Summit .
