The Aprilaire 62 humidistat includes a built in blower activation switch. It also has a digital display on the front cover to show you how humid it is in your home. Comes with outdoor air sensor. Can be retrofit installed on any humidifier with a 24 volt AC control system to make it AutoTrac style. Includes installation instructions. This system will automatically lower and raise the humidity setpoint as the outdoor air temperature changes. Humidistat must be mounted to the return air duct ahead of the humidifier.
The control automatically adjusts your home’s relative humidity (RH) based on the outdoor temperature. You will receive the optimum amount of humidity so that your home and its furnishings are protected from the damaging effects of excess condensation or low humidity during the heating season.
Simple operation with few adjustments. The control eliminates the need to manually adjust when outdoor temperature changes. It also eliminates the need to turn the dial setting to OFF during the summer season.
