Impossibility to change Temp range

[ClementR44]

Hi,

I am currently working with python example on Python 3.7 on Windows, and I cannot figure how to change the temperature range in the generic.xml. While i keep uncommented the temperature settings lines, mi log file says
DEBUG [IRImager.cpp:295] @ 0.197513s :No temperature range configuration specified. Setting default values tMin: -20 , tMax: 100
But if I uncomment the designated lines, and change the min/max value from their default setting, I get no return from the camera and the error at the end of the log file :
ERROR [IRImager.cpp:444] @ 1464.24s :Error setting temperature range and frame rate. Check videoformatindex for validity.

I also tried to change the videoformatindex parameter but can't figure out what is supposed to indicate valid temperature range.
How can I fix this ?
Thanks,
