Is that the ambient temperature display? Older models has it disabled by default.
Mine is just one of the options that come up when you go through the button pushes. Not sure how low it goes though, luckily it is going to rebound to near 30 tomorrow and up near 40 by Sat!!! Yippy
I'm glad my Mirage will probably never see temperatures that low (neither will I!). It's been pretty cold here the last few days though, enough to trigger the snowflake! (37F)
