## Long description

GreenBlue GB390 is a battery-powered irrigation controller made for outdoor garden use. The unit features an IP55-rated enclosure that protects against dust and water jets, a built-in display for setting and monitoring programs, and adjustable irrigation frequency with watering intervals from 1 to 300 minutes. The controller is designed for straightforward installation and operation, powered by two 1.5V AA batteries for cordless placement where mains power is not available.
Advantages
The controller’s IP55 protection makes it suitable for exposed garden installations while the built-in display provides clear status and programming feedback without needing additional tools. A wide range of watering durations—from a minimum of 1 minute up to 300 minutes—allows precise control for small flower beds or longer soakings for larger planting areas. Battery power simplifies siting the device and reduces installation complexity.

Usage recommendations
