How it Works

To configure the Rain8 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 in two different operational modes:

Automatic Zone Programmed Mode

Any of the X10 controllers 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.

Manual Computer Controlled Mode

This mode requires the use of a home automation program (such as HAL) 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 in this mode.
