TEMPERATURE AND HUMIDITY

The temperature and humidity section of the main dialog shows you:

The current indoor and outdoor temperature.

The current indoor and outdoor humidity levels.

Min and Max values for both indoor and outdoor temperature.

Min and Max values for both indoor and outdoor humidity.

To view or reset the min or max values for any of the temperature properties, please refer to the Min Max Values section.

To view or set alarm triggers for any of the temperature properties, please refer to the section on Setting Alarms.

DEWPOINT TEMPERATURE

WHAT IS THE “DEWPOINT”?

The dewpoint is the temperature where moisture in the air condenses into water. We commonly refer to the condensed water as dew, therefore the temperature at which the “dew” forms is called the dewpoint.

THE RELATIONSHIP BETWEEN DEWPOINT, TEMPERATURE AND RELATIVE HUMIDITY

When the dewpoint is near to the current temperature, we have very high humidity. If the dewpoint is equal to the current temp, that is a relative humidity of 100%. This means that the air is completely saturated with water vapor.

When the dew point remains constant and the temperature increases, relative humidity will decrease.

As the air temp goes down, the dewpoint tends to follow. A low dew point can go along with a high temperature only at extremely low relative humidity.

HOW DOES THE DEWPOINT AFFECT ME?

We tend to be more uncomfortable as the dew point increases. As the body’s temperature goes up, we begin to perspire and produce sweat to cool down. High humidity (and therefore a high dewpoint), will prevent the evaporation of sweat and reduces the body’s ability to cool itself, and we feel hot and uncomfortable.
