Hello,
I purchased the device based on the following on the web page. Clearly states operating temperature down to -40C. This device meets my needs but I live in Canada and I need it to operate in an unheated shed where temperatures can get to -30C or even lower.
Fortunately I read the specification sheet that comes with the device, it says operating temperature to -20C. Then I see another reference that indicates 0C to +40.
This is a critical specification for use in Canada. Which one is correct?
