Trane Bacnet Card Needed For Chiller Needed
We have an outdoor air-cooled chiller:
# RTAA070AY01A3DOM
# U97G038XX
Does anyone know the proper Trane Part Number for an add-on Bacnet Interface card that we could add to this chiller?
It currently has a Comm3 interface to a Tracer100 panel that we want to get rid of.
We are getting conflicting "opinions" on whether the card is available or not and need to order it immediately, if available.

This chiller would be a UCP1, there's no BACnet interface available for this chiller, neither is LON for that matter. You'll need a BMTW BCU to serve you info.

for a bacnet solution the only option with Trane is a BCU - pretty expensive for one unit. you're better off trying to retrofit with LON cards but even that is tough I think after the fact...

I had a similar problem, check-out Tranes literature for a BCI-I, which does a single unit and is about 75% then cheaper BCU. The job I was working on didn't go forward, so I never got to see if they are ok.

Jogas, you can only use a BCI-C on the CGAM or RTAC chillers
