Thank you Reinhard, that is extremely helpful. I will set the threshold higher now I understand how it works.

I had some trouble with understanding, too. So I asked at GTAC... overtemp-threshold <%> relates to the temperature range specified in the product datasheet. For C2 it is: Standard Operating: 0° C to 50° C (32° F to 122° F) In general "range" = "temp max" - "temp min" "threshold" = "temp min" + "range"*"overtemp-threshold <%>" For Celsius and 50%: Range is from 0 to 50 degree C = 50 degrees Threshold = 0° C + 50*50% = 0° C + 25 = 25° C For Fahrenheit and 50% Range ist from 32° F to 122° F ? 90 degrees Threshold = 32° F + 90*50% = 32° F + 45 = 77° F (same as 25° C!) > The units obviously report on their actual temperature, so how does that > relate to the threshold percentage, and what would be a "safe" value to use? We selected 80%, since that's close to max and should not be exceeded (our point of view!). Kind regards Reinhard -- Dipl.-Ing.
