SmartVentilation's Indoor Humidity / Temperature Controller With Manual Radon Level Control

A dual purpose controller. Automatically maintain acceptable indoor relative humidity and allow easy, manual adjustment of radon level / ventilation rate. Creating a controller that would allow us to adjust the radon level by adjusting airflow rate of the Daisy and Red/Black Zephyr so that the adjustment would not drift, but would remain precisely correct for years. And we managed to do it. Tamper resistance was important. All it takes is a jeweler's screwdriver to turn a small screw, clockwise to lower average radon level,  Our plan was that our fans would also be speed controllable by electronic signal from indoor air quality conditions instruments.. The Daisy and the Red/Black Zephyr may be proportionately controlled by our CO2 controller, micro pressure controller, and proportional , relative humidity controller The instrument monitors indoor relative humidity minute-by-minute and takes immediate action to prevent high indoor relative humidity and risk of mold.
