Product HighlightsWorking in conjunction with an Aprilaire® damper, the Ventilation Controller makes decisions regarding when – and how long – to ventilate through continuous monitoring of indoor relative humidity, outdoor temperature, and user-adjusted timer settings. The Aprilaire® Ventilation Controller will not open the damper to the outside air if there is a chance of raising the humidity inside the house to high levels.
