Not true for at least 1 version of mechanical and 1 (probably many)
versions of electronic thermostats, which have means of compensating for
overshoot, and therefore switch at differing points under differing
conditions. Said adjustments are often out of whack if ignorant persons
mess with a thermostat they don't understand the subtleties of, or
install a new one without reading the directions. Thus the automatic
adjustment that someone else mentioned for a newer electronic 'stat.
