Optional Dehumidistat An optional dehumidistat can be connected to the furnace to help eliminate excessive moisture during the heating season. When the dehumidistat senses moisture in excess of the control setpoint, the blower will be overridden into high speed. This will increase the ventilation airflow and create a dehumidification affect. Typical settings are between 30-40 during the winter and OFF for all other seasons.
