Feature: 1. Double Relay Output: This humidity controller has two relay outputs and can be connected to both a humidifier and a dehumidifier simultaneously. Control humidity by setting target values and differential thresholds, enabling automatic switching between humidification and dehumidification modes to maintain desired humidity levels. 2. Easy to Use: Features large dual LED displays showing both measured and set humidity values at the same time. Simple plug-and-play design with three intuitive operation buttons. Includes a 5.9 ft (1.8 m) power cord for added flexibility and a hanging slot for convenient mounting. 3. Reliable and Safe: Provides visual and audible alerts for high and low humidity conditions, sensor failure warning, and compressor delay protection. Uses a 16 AWG power cord and 10 A relays to reduce overload risk and minimize heat generation. 4. Precise Control: Equipped with a high-quality humidity sensor for accurate monitoring and regulation within a range of 5–99% RH, with ±3% RH accuracy and 0.1% RH resolution. Includes humidity calibration functionality for enhanced precision. 5. Versatile Applications: Supports up to 1500 W load capacity, compatible with humidifiers, dehumidifiers, fans, and ventilation systems. Suitable for greenhouses, grow tents, mushroom cultivation, hatcheries, reptile enclosures, germination chambers, and home use.
