Ventilation control kit (Includes Control, Damper And Transformer) Installed as part of your home's heating and cooling system, the Aprilaire Ventilation Controller makes decisions regarding when and how long to ventilate. It does this through continuous monitoring of indoor relative humidity, outdoor temperature, and user-friendly adjustable timer settings.
Indoor relative humidity is monitored to help prevent high humidity conditions inside homes. The Aprilaire Ventilation Controller will not open the damper to outside air if there is a chance of raising the humidity inside the house to high levels. The Aprilaire Ventilation Controller is designed to prevent indoor relative humidity levels from increasing beyond 60% due to ventilation.
If the outdoor air temperature is below 0 degrees F or above 100 degrees F, the motorized, normally-closed damper to the outside wall will not open.
