Anyone ever work with Trane Tracer Summit BCU? I am 1 year into doing industrial/commercial Hvac 5 years of Hvac experience. I am doing a PM on a building that uses Summit BAS. I am not a controls technician, so I haven’t gone too deep into the issue I am having, outside of normal troubleshooting. Each floor has multiple water source heat pumps. On the BCU, I get an event “comm failure”. I seem to have an intermittent issue on a few units. It will be down and then a few minutes later go back up. I found a forum that went into some detail about a similar issue a guy was having. Was hoping someone may be able to shed some light on the problem before having to contact trane. Not sure if these pictures help, but it’s from one of the water source heat pumps.
