Claim 8:
9. A control system, comprising:
a sensor configured to measure a dew point of air;
a dehumidifier assembly, including an air driver;
a damper assembly fluidly coupled to the dehumidifier assembly, the damper assembly comprising:
a first damper that controls an exchange of air with an external environment surrounding a building;
a second damper that controls a recirculation of conditioned air from a space within the building; and
a connecting member coupled to both the first damper and the second damper and configured to move the first damper and the second damper; and

a controller communicably coupled to the sensor, the dehumidifier assembly, and the damper assembly, the controller configured to:
receive a dew point set point;
determine a dew point of the conditioned air from the space within the building from the sensor;
in response to determining that the dew point satisfies the dew point set point, determine a vent air dew point of air in the external environment surrounding the building; and
in response to determining that the vent air dew point is below the dew point set point by a dew point threshold:
controlling the connecting member to position the first damper in an open position to exhaust the conditioned air to a vent exhaust opening fluidly coupled to the external environment, and to position the second damper of the damper assembly in a closed position to substantially prevent recirculation of the conditioned air to the space within the building; and
controlling the air driver to exhaust the conditioned air from the space to the external environment; and

in response to determining that the vent air dew point satisfies the dew point set point or is within the dew point threshold of the dew point set point:
controlling the connecting member to position the first damper in the closed position to substantially prevent exhausting the conditioned air to the vent exhaust opening and positioning the second damper in the open position to recirculate the conditioned air to the space within the building; and
activating the dehumidifier assembly to reduce a moisture level of the conditioned air within the space within the building.
