Abstract
A method of controlling indoor air humidity includes determining a dew point set point and determining a dew point of air from a space within a building. The method also includes, in response to determining that the dew point satisfies the dew point set point, determining a vent air dew point of air in an external environment surrounding the building. The method further includes, in response to determining that the vent air dew point is below the dew point set point by a dew point threshold, controlling a connecting member of a damper assembly to position a first damper of the damper assembly in an open position to draw in vent air from the external environment into the space, and to position a second damper of the damper assembly in a close position to substantially prevent recirculation of air through the dehumidifier.
