The temp printed on it is the temp at which it should start to open (=/- a few degrees. Fully open at about 10 to 12C deg above that.
Thanks for posting this.
This is also a good test for new ones. I’ve seen someone do this test for new ones and for his choice to the ones he wanted to use. Just because there New doesn’t mean the all don’t open up at the same temp.
