  An unpleasant smell near your Airflow Fan could be due to an empty condensate trap (U-bend), a condensate pipe that's not fully in the trap, or a blocked/frozen condensate pipe or trap. Try filling the condensate trap with water or pushing the pipe deeper into the trap. Also, check the condensate drain and clean it if needed.

  If cold outdoor air is entering your home via the Airflow Fan, several factors could be responsible. The air might be cooling down in the attic ducts, so check the duct insulation. Also, the heat exchanger might be frozen, in which case you should contact your supplier/installer to reduce the set point of the frost protection facility. Make sure that the filters and the heat exchanger are clean.
