Description:
This compact digital humidistat provides straightforward, plug-and-play control for both humidifiers and dehumidifiers, allowing automatic switching between humidification and dehumidification based on set values. It is designed for environments where stable humidity matters, such as grow rooms, storage spaces and home comfort systems, and it includes protections like compressor delay and sensor error alarms for added peace of mind.
Key Points
The controller operates without wiring, so setup is simply a matter of plugging your devices in and setting the target humidity. It can measure a very wide humidity span and will switch modes automatically between humidifying and dehumidifying according to the values you configure. ⚙️
Alarm functions notify you if humidity exceeds limits or if the sensor reports an error, reducing the need for constant monitoring. The unit also includes compressor delay protection to help extend the life of refrigeration equipment, and the humidity can be calibrated according to the manufacturer’s instructions. 💧
Note a possible limitation: this model does not include built-in Wi‑Fi or remote app control, so it may not be the best option if you require networked monitoring or logging.

Usage Recommendations
Use the controller to automate a humidifier and a dehumidifier or to operate a fan according to relative humidity thresholds. For example, set a target humidity and a differential value to avoid frequent switching, which also respects compressor delay protection. When installing, place the sensor away from direct airflow of devices to prevent skewed readings and allow the sensor to stabilise for accurate calibration.
If precise remote monitoring is required, consider pairing this unit with a separate data logger or a smart plug that records conditions, because the controller focuses on direct, local control rather than network features. According to the manufacturer, repeated condensations do not affect reliability, but periodic checks of the sensor and calibration are advisable for critical applications.
