As I have said before, I am not a pilot but have done a lot of lab work involving programming.
Any program has to "sanitize" inputs before they enter the main body of the program.
If my subject's temperature has been a steady 37degC for the last two hours and suddenly starts reading 30degC then there is something wrong with the probe or it's connection or attachment to the subject.
And the program has to respond in a sensible way, i.e. NOT turn up the thermostat to 40degC in an attempt to warm the subject, but have been told that such an sudden drop is impossible and give me an appropriate informative warning - "UNEXPECTED TEMP FALL - CHECK PROBE ATTACHMENT AND CONNECTION"
