The Eva-Dry EDH-1 Hygrometer Humidity Reader is designed to work with your dehumidifier or humidifier to monitor the relative humidity (RH) of your room, control the power to the unit, and maintain the desired RH level.
To use, simply plug the EDH-1 Humidity Reader into your wall outlet, then plug your dehumidifier or humidifier into the outlet on the front of the EDH-1. Using the controls, set the desired RH level between 30%-90% and the mode to humidify or dehumidify. The EDH-1 will turn the unit on or off to maintain your desired RH level.
The EDH-1 is the perfect enhancement to Eva-Dry’s EDV-1100, EDV-2200, and EDV-2500 to customize your comfort experience.
