Faran analogue hygrostat – humidity controller

Faran Analogue Hygrostat is a reliable analogue controller for automatic humidity management in grow rooms, greenhouses, nurseries and other climate-controlled spaces. The device monitors relative air humidity and automatically switches a humidifier on or off to maintain the set level, without complex settings or an internet connection.

Faran Analogue Hygrostat is a practical solution for automatically maintaining optimum humidity in plant-growing spaces. Instead of constantly monitoring and switching on the humidifier manually, the device controls relative humidity and manages the connected humidifier according to the preset value.

Thanks to the analogue control, setup is quick and intuitive. No apps, Wi-Fi connection or digital programming are needed – simply set the desired humidity level with the rotary potentiometer and the hygrostat automatically takes care of the rest.

The device is designed to work with humidifiers such as Faran HR15, Faran HR50 and other standard humidifiers controlled by switching the power supply on and off. When the set humidity is reached, the hygrostat cuts power to the humidifier; when it drops below the set value, it switches it on again.

For best results, the manufacturer recommends installation at plant canopy height and away from the humidifier's direct airflow, to avoid inaccurate readings.

📋 Instructions for use

1. Mount the hygrostat on a wall at plant level.
2. Avoid mounting directly next to the humidifier or in the direct path of the water mist.
3. Connect the humidifier to the hygrostat.
4. Set the desired relative humidity using the rotary control.
5. Leave the system running for several hours and check the humidity with a thermo-hygrometer.
6. If necessary, fine-tune the setting until the desired level is reached.

⚠️ Important: For the most accurate readings, place the hygrostat away from the humidifier’s direct airflow, heaters and ventilation openings. This gives a true humidity reading in the plant zone and more precise climate control.
