The Rain8 is a full featured, 8 zone irrigation controller that may be linked together to provide a maximum of 256 zones of operation. A must for automating lawn sprinkler systems.
A complete irrigation schedule can be triggered by the reception of a single X10 power line carrier command. With its dual mode capability, each individual zone can be controlled independently if the user prefers. Using a PC and software sold separately, all aspects of irrigation may be controlled locally or even over the Internet*.
How it Works
To configure the Rain8 8 Zone Irrigation Controller you connect it to your computer (Windows or Mac) and run the configuration utility application. This allows you to define the X10 address zone assignments and set the operational mode. For maximum flexibility, once programmed you can run the Rain8 8 Zone Irrigation Controller in two different operational modes:
Automatic Zone Programmed Mode
The Rain8 8 Zone Irrigation Controller can be used with nothing more than X10's Mini Timer. Anything that can generate a X10 command can trigger a complete irrigation sequence, cycling through all eight zones. When one zone times out, the next one starts. In this instance the time settings for each zone are stored internally. The Rain8 provides for two independent schedules, each with its own X10 trigger assignment and run times.
NOTE: The Auto mode is not implemented in the two-way Rain8II model.
Manual Computer Controlled Mode
This mode requires the use of a home automation program to generate X10 power line carrier signals to start and stop each zone. The actual timing controls, in this mode, are located in this PC program. This provides an easy means of adjusting run times for seasonal irrigation changes. As a safeguard, the user can set the maximum "valve on" time for each zone anywhere from 1 to 240 minutes. This guarantees that the sprinkler valve will turn off even in the absence of an X10 OFF command. As each sprinkler valve has its own default setting, this guarantees a minimum of wasted water in the advent of a lost X10 signal. Another safeguard to help in the conservation of water is the inter lock feature. Only one sprinkler valve is allowed on at a time.
