The Rain8 II 2-Way Model With the 2-way version of the Rain8, you can determine which irrigation zones are on and which are off. Designed for use with X10-compatible computer interfaces and other devices that can generate the X10 Status Request command. In addition to giving you the power to poll irrigation zones to determine their on/off status, it also allows your computer send a command to the module then check to see if the command was carried out. If not, the computer can automatically send the command again.
Other differences between the two-way and the one-way Rain8:
There are no limitations on the number of zones that may be active at one time.
Default run timers can be disabled if desired.
Responds the X10 "All Units Off" command.
Manual mode only, does not have the auto mode capability of the one-way Rain8.
The Rain8 or Rain8 II requires a TW523, PSC05 or Powerlinc power line interface module.
