If you have an old thermostat and need new equipment, it’s strongly advisable to get a thermostat with the new equipment; it’ll look nicer. Another time to get a thermostat is when you’re going for two-stage equipment and have a single-stage thermostat. You can use a single-stage thermostat with two-stage equipment, but a genuine two-stage operation is better, and you can get that with a two-stage thermostat.
However, if you’re operating two-stage equipment, you need a new thermostat. Conversely, if your thermostat doesn’t have the features you like, and you want features like, program mobility or internet operation, you’ll have to buy a new thermostat. If your thermostat’s old and out of calibration, it’s old enough to be an old electromechanical that you’ll have to buy a metal spring.
Can the New/Digital Ones Get Out of the Calibration?
What happens with the digital ones is that they outright fail. Their electronics will get to a point where they won’t operate properly. Their batteries became weak sometimes, which is a sign of deterioration. But, technically, they don’t fall too much out of calibration. They just quit.
Bottom Line
Most times, our attention is always on the equipment, not the thing that runs the equipment.
