K-rain BLUE-2 - 2 Bluetooth Battery Powered | 1-Station Waterproof Timer

Product Details

The K-Rain BLUE-2 is a professional-grade, 2-station irrigation controller designed for environments where AC power is unavailable or too costly to install. This rugged, battery-operated timer is fully managed via a smartphone or tablet using the free K-Rain BLUE App, eliminating the need to climb into muddy valve boxes for programming. Built for the toughest conditions, the BLUE-2 is IP68 certified—meaning it is 100% waterproof and fully submersible. It is the ideal solution for highway medians, roundabouts, remote gardens, and multi-housing developments where traditional wiring is impractical.

Key Features:

• Bluetooth Smart Technology: Program, start, or suspend your watering schedules from up to 35 feet away using your iOS or Android device.
• IP68 Waterproof Rating: Fully submersible and dust-tight, allowing for direct installation inside the valve box without fear of water damage.
• Cloud-Based Management: Features a virtual backup that stores your programs and preferences in the cloud for easy restoration if a device is replaced.
• Geo-Location & CrewView™: See every controller on a map and allow your field team to view site programs remotely for total fleet visibility.
• Flexible Scheduling: Offers 6 independent programs with 8 start times per program, along with seasonal adjust (10% to 200%) to conserve water.

Installation & Maintenance Tips:

• Solenoid Check: Ensure your valves are equipped with 9V DC latching solenoids; standard 24V AC solenoids will not function with this controller.
• Start-Up Procedure: Some DC solenoids default to the "open" position. After installation, use the app to "Test All Stations" for 2 seconds to ensure all plungers are seated and valves are closed.
• Battery Life: Check the battery status icon in the app regularly. Replace the 9V battery at the start of every season to ensure uninterrupted operation.
• Security: Add a passcode lock to each controller via the app to prevent unauthorized access or programming changes in public areas.

Common Uses/Applications:

• Public Medians & Roundabouts: Eliminates the need for expensive trenching and road crossings for power lines.
• Remote Agricultural Zones: Manages localized irrigation in fields or nurseries without a central power grid.
• Home Hardscaping: Ideal for adding zones to an existing yard when the main controller has no available stations or wire runs are blocked by patios.

Common Questions:

Q: Can I use this with a rain sensor?

A: Yes. The BLUE-2 is rain and rain/freeze sensor ready. Simply cut the yellow wire loop and connect your normally closed (NC) sensor.

Q: What happens if I forget my passcode?

A: You must disconnect the battery and create a short circuit on the battery terminals for 10 seconds to factory reset the module.

Q: How many controllers can I manage?

A: The K-Rain app allows you to manage hundreds of controllers from a single interface, making it perfect for commercial property managers.
