Then you need to travel to a location where it's colder than where you're currently situated....

Seriously though, don't you have another thread where you're discussing that topic?

As I said in that thread, BYTES and WORDS in PBP aren't signed so comparisons like If myValue < 0 won't work because myValue (if it's a BYTE or WORD) will always be considered to be either zero or larger than 0.

Apart from that I'm not up to speed with what you're doing, how you're measuring the thermistor, what values you're getting for different temperature etc.
