Thanks for the Log. At this point Jared or someone will need to take a look as I'm not sure what's happening.
However I don't think you understand how cooling works. If you set the temp at -20C the camera is trying to get to -20C. Your camera has a max delta T of about -40C, meaning that no matter what the air temp the camera can get -40C max below that air temp. So if it is 25C air temp, the coldest the camera will be able to get to is -15C.
So if you set -10C in 5min in the profile, that means the camera will try to get to -10C in 5min regardless of what the air temp is. It does NOT mean -10C from the ambient air temp.
