Automatic foundation vents take the worry out of remembering to open and close vents as the weather changes so the home can be protected from decay. These vents will open and close automatically depending on the air temperature. This helps the appropriate amount of air to circulate under the structure. No electricity is needed.
For help in unusual situations, Elite will also offer the Power Temp-Vents to force ventilation to non-ventilated areas and is controlled by an electric humidistat or thermostat.
