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 dis-
played perceived temperature is calculated solely from tem-
perature and humidity and is measured by the outdoor
sensor.
27 Dew point
Press the INDEX button several times until DEW POINT is
displayed.
Note:
The dew point is the temperature below which the water va-
por in air at constant barometric pressure condenses into li-
quid water at the same rate at which it evaporates. The con-
densed water is called dew when it forms on a solid surface.
The dewpoint temperature is calculated from the indoor
temperature and humidity measured at the main unit.
