The AprilAire Model 62 Low Voltage 9-Wire Automatic Humidifier Control (Humidistat) with Digital Display works with your AprilAire Whole Home Steam Humidifier to accurately maintain the relative humidity in your home.

This Humidistat may also be used in Manual Mode if you prefer to adjust the humidity setting yourself.Blue LED backlit LCD display shows RH% and the set point when adjusting it up or down. Features integrated Blower Activation function that maximizes humidifier run time by running with the heat and fan cycles of an HVAC system, or, if additional time is needed, it can bring the HVAC fan on itself. Model 62 offers fully electronic control that is accurate to within +/-3% RH, and it is compatible with AprilAire Whole House Steam Humidifiers in the 800 Series.LED Indicator lights provide visual feedback when the humidifier is on and when service is needed. When in Manual Mode, the digital display conveniently shows a letter "M" as a reminder. This Humidifier Control must be mounted on the return air duct. For proper operation, the Humidifier Control must be at least 6 inches upstream of any of the following: Humidifier, Humidifier Bypass Ductwork (if applicable), and/or Fresh Air Intake Ductwork (if applicable). Requires a sheet metal duct hole opening of 3/4 inches in diameter for the RH sensor. Model 62 also includes a gasket to help reduce air leakage between the duct and the control housing.
