Your new thermostat is so smart, it’s almost human.
■ Your body perceives temperature from a variety of
sources, not only from the air in the room, but also from
your surroundings—walls, windows and furnishings.
■
Human beings feel differences in temperature as slight
as one degree Centigrade.
■
Common household thermometers and standard ther-
mostats sense only air temperature, which may or may
not reflect how hot or cold the room actually feels to a
human being.
■
Your new thermostat reads the temperature of the wall
as well as the air—and responds to temperature
changes as little as one degree Centigrade—so room
temperature is more likely to
feel right to you and your
family.
