Well with mine in the UK you get the bleep at 4 deg C with is 39.14 deg F. Now its been a while since last winter but I thing it bleeps again either 2 deg C or 0 deg C if I remember correctly.
I think is does say something in the handbook. You can change the temperature display from F to C or C to F if you want this?
