Setting Temp Range - Carrier Transicold?

I know this is an old thread, but in case anyone else wants to know about this. I have a Carrier 2500A unit and there are some settings you can change and some you can't. Depends on setup by the owner.

There is a setting called an Intelliset called Range Protect will give you a range that only turns on the reefer if it falls outside a 35-60 degree temp. Like Goldilocks, not too cold, not too hot.

There is also a setting that gives you the ability to control what variance the reefer will turn in at like 3,5,7,10 degrees. It will turn on the reefer if the temp falls outside that specified range.
