Notice:
The perceived temperature is based on the common effects of temperature and humidity. Heat index
is only calculated when room temperature is at 27° (80° F) or higher. The displayed perceived temper-
ature is calculated solely from temperature and humidity and is measured by the outdoor sensor.
42 Dew point
Press the INDEX button several times until DEW POINT is displayed.
Note:
The dew point is the temperature below which the water vapor in air at constant barometric pressure
condenses into liquid water at the same rate at which it evaporates. The condensed water is called
dew when it forms on a solid surface. The dewpoint temperature is calculated from the indoor temper-
ature and humidity measured at the main unit.
