Bermad GreenApp-402, Single station Bluetooth controller on 3-way base

The Bermad GreenApp-402 is a smart, compact, battery-operated Bluetooth irrigation controller designed for standalone valve control in remote or off-grid irrigation systems. Integrated with a 3-way latching solenoid actuator and hydraulic pilot valve, it provides precise valve control with minimal power consumption—making it ideal for locations with no wired power or signal infrastructure.

With a user-friendly Android and iOS app, the GreenApp-402 allows intuitive wireless programming and management from your smartphone or tablet at distances of up to 30 meters. The controller consumes power only during position switching, enabling up to three years of operation from two standard AA alkaline batteries. Its IP68-rated casing ensures dependable performance in dusty, wet, or dirt-laden environments.

The pre-assembled 3-way solenoid base includes a manual override and universal mounting bracket for fast and easy installation on any standard hydraulic control valve or solenoid manifold.
