11-15c is preferred? Yet living in a house with average temp under 18c is harmful to health according to studies and the average recommended temp is 20c according to what I am reading across multiple governments worldwide.
So please, could you cite your source that 'dying of cold' is the preferred temp of humans?
Looks like you replied to the wrong person. This should have been for the person above them who claims that windows obeys settings that are set properly.
Not the person who realises that's a crock of s#!t
