Press the [INDEX] button repeatedly until DEWPOINT appears.
Note: The dew point is the temperature below which the water vapor in air, at a constant
barometric pressure, condenses into liquid water at the same rate at which it evaporates. ‘Dew’ is
the term used to describe the condensed water that forms on a solid surface. The dew point
temperature is calculated from the indoor temperature/humidity measured at the Main Unit.
