Add a conditional range for Farenheit.

When the device is set to Farenheit, it is going to need a different range.
The 60-115 is a rounded conversion of the Celsius range, as a guess.
But the Celcius range is a bit suspect, I found a manual online that states
18-35, but the user who submitted the request was adament that it goes beyond
40 (there were other unknown dps reporting 18 and 40, so I thought the range
might be coming from them).
