Avec l'arrivée des vacances, vous commencez à vous demander comment vous allez retrouver votre jardin et vos plantes d'intérieur à votre retour. Vous pensez bien à votre famille, vos voisins ou vos amis proches pour venir rendre visite à votre jardin en votre absence mais ils ne sont pas toujours disponibles et surtout vous préféreriez ne pas les ennuyer avec votre jardin.
Le Rain8II vous donne la solution!


Le rain8II est un module autonome dont on effectue la programmation via le port RS232. Une fois la programmation réalisée, il n'est plus nécessaire de le laisser connecté au PC. Le déclenchement du programme (ou d'une des séquences de programme) s'effectue via des ordres X10 envoyés sur le courant porteur. Pour ce faire, il est nécessaire d'interconnecter le module RAIN8II au courant via le XM10 (interface TTL <-> CP, inclu dans ce pack).

With this 2-way version, 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 to 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.

How it Works

To configure the Rain8II 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.

• 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.

Requirements and Specs
The Rain8II requires a X10 power line interface (included) . You will also need to purchase a 220v AC to 24v AC transformer (the Rain8 operates on 24 - 27 volt AC, 50 or 60 HZ).
