in what world is a mere 10-14 years anywhere nesr acceptable? Mx parents home that was bzild in the 80s still has the original thermostats and I expect they will not replace them in theor lifetime. And this is not an exception, its the rule and should stay like that

How much functionality does that original thermostat have?
