We have a Trane BCU (BMTW) installed around 2003 that enables the data pull from chillers to our BAS. BCU has an error code of 8 which means "Processor in reset or no functioning software. This code will remain present if the capacity module is not inserted or totally failed".
We cycled power to the BCU and also pulled and reinserted the capacity module but no luck. I was wondering if we replace the capacity module (BRD01669), will fix this issue. Also, will there be any version issues of installing a new capacity module into the older BCU.
Thanks for your help.
