Humidity Controller Dual Relay LED Display Digital Humidity Regulator for Greenhouse US Plug

This humidity controller provides reliable, automated humidity management for a wide range of applications. It uses relay outputs to drive external devices and automatically switches between humidification and dehumidification based on set target values and hysteresis differences to keep conditions stable. Key benefits Dual relay outputs let you connect a humidifier and a dehumidifier at the same time and let the controller switch automatically to maintain the target humidity. Precise control by setting a target humidity and a difference value so equipment runs only when needed, reducing cycling and power waste. capacity and broad compatibility: 1500W output load and 10A relay control humidifiers, dehumidifiers, fans, and ventilation systems. Built for safer operation: visual and audible and low humidity alerts, sensor failure alarm, and compressor delay guard protect equipment and processes. Reduced overload and heat: heavy duty 16AWG power cord and conservative relay rating help minimize heat generation under load. Features and performance Relay outputs for independent humidifying and dehumidifying circuits; automatic mode switching based on setpoint and differential. Large LED screens display measured humidity and set humidity simultaneously for quick monitoring. Easy operation with a plug and play design and 3 simple operating buttons. 5.9ft power cord for flexible placement and a hanging sign design for straightforward mounting. Compressor delay guard prevents short cycling of refrigeration equipment and extends compressor life. Sensor failure alarm warns of probe problems so you can troubleshoot before conditions drift. Compatibility and use Controls appliances up to 1500W and devices driven by a 10A relay. Compatible with most humidifiers, dehumidifiers, inline fans, and ventilation systems used in environmental control applications. Durable 16AWG power cord reduces voltage drop and heat at typical operating currents. Practical scenarios Greenhouse climate control: Maintain seedling and plant health by automatically switching between humidification and ventilation to hold a stable relative humidity setpoint. Mushroom cultivation or germination room: Keep strict humidity ranges with audible and visual alarms and compressor delay protection to avoid equipment damage from rapid cycling. Reptile or hatching enclosures: Use dual outputs to connect a humidifier and a ventilation fan so the controller can respond to rising or falling humidity without manual intervention. What you get A straightforward humidity controller with dual relay outputs, large display, audible and visual alarms, compressor delay guard, 16AWG power cord, and a 5.9ft lead for flexible installation and reliable environmental control.
