How accurate is the Lyric thermostat?
The Lyric is designed to keep your home temperature within 1 degree (a 1 degree differential) of your desired temperature. Your Lyric uses both the ambient temperature of the air and the radiant temperature of the wall it is mounted on to determine the average temperature, then rounds up or down to the closest whole degree. Although it tracks the temperature internally in real time, the display is updated only every few minutes. This provides a more comfortable, consistent temperature along with a more stable display.
