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

The Irritrol RD600-EXT-R Rain Dial is an outdoor irrigation controller designed to manage up to six watering zones across your yard. It serves homeowners and property managers who need precise scheduling flexibility for varying landscape elements like lawns, gardens, and shrubs.

This unit features three independent programs, allowing you to create custom watering routines tailored to specific plant materials. It is also compatible with Contractor Residential Remote (CRR) series controls, enabling remote adjustments across your property without returning to the main box.

For added environmental management, the controller includes a dedicated terminal and bypass switch for connecting a rain sensor. It also provides a water well recovery option, which adds delays between station activations to let low yield wells recharge while giving you the option to keep the pump circuit on or off during that pause. Note that the listing indicates a six station capacity, which cannot be expanded if your landscape requires more zones.

Verdict: This controller is a solid choice for homeowners looking for dependable outdoor zone management and well protection. It provides flexible programming and remote readiness for medium sized properties.

A great fit if you:

• Need to manage up to six distinct lawn or garden zones using dedicated watering schedules tailored to specific plants.
• Rely on a water well system that requires pauses between station cycles to allow proper well recovery.
• Want the flexibility to connect a rain sensor or operate your outdoor system using a compatible remote.

Consider something else if you:

• Manage a larger property that requires more than six station connections.
• Prefer an all-in-one setup that includes the remote control unit directly in the initial purchase package.

Can I connect a rain sensor to this irrigation controller?
Yes. The unit features dedicated hookup terminals for a rain sensor as well as a built-in sensor bypass switch, allowing you to easily override the sensor when manual operation is necessary.

How does the water well recovery delay function?

What type of remote controls work with this model?
This outdoor unit is compatible with the Contractor Residential Remote (CRR) series of remotes. It is remote control ready, though the remote transmitter unit is not included in the standard package.
