Because it’s mass produced consumer goods operating on a “below x temperature turn on heat/turn off AC” and “above y temperature turn off heat/turn on AC”. Old ones are just bimetallic strips where you change the trigger position with a slider, and modern ones use commodity grade temperature sensors, and neither is guaranteed to be placed particularly far from the vent.
I have not seen any thermostats in Europe with decimal degrees. But I also don’t think a thermostat is necessarily accurate to that level anyway.
I have always wondered why electronic thermostats use 0.5°C increments and the answer seems to be Fahrenheit compatibility.
Thanks for confirming they exist. I have never seen one that precise.
lol you don’t think it’s accurate to a degree Fahrenheit? Why wouldn’t it be?
