Breakthrough Technology Senses Temperature More Like You Do
Your Deluxe Programmable 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.
• Humans feel differences in temperature as slight as two degrees Fahrenheit.
• Common household thermometers and standard thermostats sense only air
temperature, which might or might not reflect how hot or cold the room actually
feels to a human being.
• Your new thermostat reads both the temperature of the wall and the air—and
responds to temperature changes as little as one degree Fahrenheit—so room
temperature is more likely to feel right to you and your family.
