Irritrol RD600-EXT-R Rain Dial 6-Station Outdoor Irrigation Controller

Introducing the Irritrol RD600-EXT-R Rain Dial 6-Station Outdoor Controller, a compact hub built to manage diverse landscapes. Part of the Rain Dial R series, this unit supports six zones and is designed for outdoor use, delivering reliable scheduling across lawns, garden beds, and mixed plantings.

Flexible programming for diverse plant material

Three independent programs give you the ability to tailor watering times for different zones and plant types. Set varying run times and days to match seasonal needs, calibrating irrigation to your landscape’s rhythm.

• Think of separate schedules for turf, shrubs, and irrigation-friendly beds.
• Switch between programs to accommodate changing weather and plant growth.
• Schedule wind-down or fade-in starts to reduce water stress on sensitive species.

Remote control and sensor readiness

• Remote control readiness compatible with the CRR contractor residential remote series for convenient adjustments.
• Rain sensor ready with a bypass switch and a dedicated terminal for sensor hookup, helping you integrate rainfall data into your plan.

Smart water management and pump coordination

• Water well recovery with a delay between stations option to optimize pump cycling and water use.
• Optional pump circuit control that can be turned on or off during each station’s run to fit well or reservoir constraints.

What this means in practice is a versatile controller that supports careful zoning, sensor-aware watering, and practical automation for a variety of landscapes. While results depend on setup, you can explore more precise irrigation without sacrificing simplicity.
