- 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.
- With this controller and a precise ventilation rate, it is unlikely that you will need a costly and bulky dehumidifier because of radon system operation unless your air conditioner is oversize or cannot achieve a delta t of 18 degrees or better.
