Blue DEF head heater light on dash

I have an intermittent blue DEF head heater light come on twice now in past 100 miles. I am in FL and dash show temp is 115 degrees so not sure why heater light came on any ideas.

No error codes just blue heater light twice but makes no sense. What does this light mean?

Mine comes on just about every time I start engine, hot or cold I mentioned that to Cummins when I was there 2 months ago and they said that was normal
