A unique water conservation feature is the default or maximum run time values. In event of a lost X10 OFF command, the run time is determined by this default setting. Each zone has its own default value.

The default values may be any value between 0 and 250 minutes. In most cases this value would be slightly larger than the greatest run time that would ever be considered for this particular zone. The example shown, zone 1 is set to 3 minutes because it is used in a green house, controlling a misting head that never runs longer than 2 minutes. Entering a 0 disables that particular zone.

This lets you assign an individual X10 code to each sprinkler valve. You have the option of using any of the usual X10 house codes and either 1 - 8 or 9 - 16 unit codes. In the example shown here, sending X10 code E-1 ON will turn the zone 1 sprinkler valve on. Send it an E-1 OFF and the sprinkler valve turns off.

Once you have configured your Rain8 with the desired X10 addresses and default run times you can turn your attention to everyday operation.

The most effective means of generating the necessary X10 ON & OFF commands is a PC with home automation software running on it. All aspects of irrigation may be controlled over the Internet if desired or locally if preferred.
