I could not believe it when I realized this month that the dial control device I have that runs my central heating and ac system is over 30 years old! And it is still working just as great today as when I purchased it over 3 decades ago.
This is the sign of great craftsmanship and it also shows that a dial control device may in fact be the best control device around.
In my opinion I would say forget about all these stupid advanced forms of Heating and A/C technology that are all so complicated to older folks care like me. Things like smart control units and even the typical digital control units. They may look and be futuristic or modern or even look cool to young folks. But they would never last 30 years! As a matter of fact from what I know, both smart control units and the typical digital control units have a lifespan of around 10 years if you are fortunate. Because most die on you within 5 years and then it is time to buy a new one. With this outdated dial control device I bet it will easily last me the rest of my life and then still be alive even after I am long gone! That is what I truthfully think just based on the fact that it has lasted me over 30 years and still going just as strong this month as it was back then. It is honestly unbelievable when you think about it. I am just so happy that I made the choice to get this dial thermostat back then. I would not have had it any other way.
