Although multiple controllers on one system aren't that uncommon in my area, I do not recommend them either. To many complications, variations and etc.. But if you still desire to go this route, this device here will simplify things.

Of coarse the real chalenge is finding a distributor that caries these! Good luck!

The Isolator webpage describes some of the interconnection problems with two timers. I would just use some homebrew circuitry with parts a Radio Shack would have in their stores, and be just as well off.

I thought I should post this as I am doing exactly what was mentioned earlier in this thread. Quite simply, isolators are way too complicated and unreliable to accomplish this. This can be accomplished via 24vac relays. Using a separate 24vac transformer, wire the two wires from the transformer to the two normally open relay contacts. wire the other two contacts to the master valve. Then using the master and common terminals of your controller, wire those to the relays, 1 per controller. Your controller is now only activating the relay solenoid. Actual current is coming from the transformer. My system has 17 controllers and the little board I made has 17 relays.

These were great, delicious, great texture. The palm sugar was a beast, I grated by hand and got a great workout. It was a solid disc from an Asian market. How do you manage yours? I tried chopping, using a metal mallet, dropping on concrete.. It di&d;#8217nt want to break up.
