6.52.3 Refrigerator Command - JLT Request

Justification: Dometic NRX refrigerators currently support night, eco and freezer modes. We are working to connect these refrigerators to RV-C and we want to give our customer’s multiplex systems / user APPs / Winnebago Connect, etc. the ability to set all of the modes that are available on the refrigerator’s HMI (Human Machine Interface).

Not an objection but a comment. This was an example we gave 20-odd years ago of what would be an appropriate amendment to the spec. In those early days we often debated about how many bits to dedicate to a field and where the line should be drawn between proprietary data and operational data. The idea of an "eco" mode for refrigerators was one of our canonical examples that has been used many times to illustrate these points. I've probably used it a dozen times in meetings and seminars over the last two decades. Now we're going to need a new example! Someone else might ask for a line or two describing what "eco" and "freezer" mean, but I don't see too much possibility of confusion in the context of a reefer.

Thanks Martin -- I'm new to this, so if you think more clarity would be helpful, I will take a look. However, it sounds like you don't think it's needed in the context of a refrigerator, so I will wait to see if anyone else requests it.
