You think I can not think the fact that this 40 year outdated dial temperature control that I have still works! I am not kidding you! This dial temperature control is 40 years outdated in addition to is a single that I had when I was growing up in our parents home. They gave it to me when they sold the home in addition to moved some years ago. I kept it in addition to used it with our very own central heating in addition to a/c plan unit. And I was thinking about it today that this thing is 4 decades outdated in addition to it still works as if it were brand current in addition to current! My central heating in addition to a/c plan is brand current in addition to current in addition to this outdated dial temperature control entirely works with it. I wonder if this dial temperature control will ever die? Well I can tell you that as long as the dial temperature control still works good as current I am going to keep it for life if I can. Because I absolutely am not a fan of new Heating in addition to A/C technology. I am not into the whole smart temperature control thing in addition to the whole smart heating in addition to a/c plan thing. I assume there are too many flaws that need to be ironed out yet that no a single talks about. I have had our experiences with smart temperature controls in addition to they are not good a singles at all. So I am ecstatic that this outdated dial temperature control is still alive in addition to kicking after all these years. It is the best.
