Product Details

Description

The Lennox Aprilaire 56 Automatic Humidifier Control is a sophisticated digital humidistat designed to maintain optimal indoor air quality by managing your whole-home humidification system. This automatic regulator intelligently adjusts the moisture levels in your home based on external conditions, utilizing an outdoor temperature sensor to prevent window condensation during cold snaps while ensuring consistent comfort. Ideal for central HVAC systems, this control unit monitors indoor relative humidity and activates the humidifier only when necessary. By automating the humidification process, it helps protect wood flooring, cabinetry, and sensitive electronics from the damaging effects of dry air. Whether you are upgrading your current HVAC controls or replacing an older manual humidistat, this digital controller provides precise, reliable management of your indoor environment.
