Supply air maximum relative humidity limitation

To prevent the risk of wet ducts, the relative humidity is limited to a value, defined by parameter SAH-01. Depending on the maximum relative humidity setpoint and the P-band SAH-02 the internal maximum relative humidity control signal varies from 0 to 100%, as shown in the next figure.
