Claim 20:
21. The method of claim 18, comprising controlling humidity of the outdoor air provided from the ventilation unit to the structure, wherein controlling humidity of the outdoor air includes:
determining a dew point temperature of the outdoor air downstream of the dehumidifying coil;
comparing the determined dew point temperature to a target dew point temperature for the outdoor air downstream of the dehumidifying coil; and
reducing magnitude of a difference between the determined dew point temperature and the target dew point temperature by sending a control signal from an electronic expansion valve controller outside the housing of the ventilation unit to the first electronic expansion valve outside the housing of the ventilation unit to change a rate of refrigerant flow into the dehumidifying coil.
