We have a 7820A GC / 5975 MSD GC/MS system that had been idle for several months. Upon restarting it, the Aux Thermal 1 (transfer line heater) setting was yellow, and scrolling over, it showed an allowed T range of 0 to 0. In configuration, Thermal Au 1 was listed as "unknown" while other thermals aux were "not installed." It kind of looks like the software is not identifying the heater. Any advice on how to proceed? Thanks
