looks like the perfect gooroos to ask. I am new to trane all around only installed/started 1 varitrac sys and am about to start up 2 tracker sys i just installed with 2 more on the way. my question is does trane offer anything for refrigeration such as to monitor a cooler. I know a typical mp503 can handle up to 4 inputs. Im looking at monitoring box temp, supply temp/but can you make the software acknowledge a defrost sequence so the alarms dont go crazy?
