That extreme settings on a thermostat won’t cause faster heating or cooling.
The other side of this frequent conversation is my husband, who happens to be among the most intelligent and erudite people I’ve ever known. He simply can’t comprehend how a thermostat works. If a room’s too hot during summer, he’ll set the temperature to some arctic level and expect instant magic. He does the same in winter; he puts the thermostat at a tropical setting and thinks the room will heat more quickly.
We’ve discussed this matter SO many times, more times than I can even recall. He always laughs at himself, good-naturedly, and says that he finally understands…that is, of course, until the next time.
