For the heck of it, i connected it up to the sprinkers and tried. I didn’t work. When i did a manual override on any of the 3 zones, the animation for each zone worked but they were not powered. I tested each zone with the volt meter and they did nothing.
I am running out of ideas.
Check your resistor arrays RN2 and RN3: make sure you’ve soldered the 220 ohm x 4 ones to them. If you accidentally soldered the 10K x 4 resistor arrays to RN2 and RN3, your valves will not be activated because the triac will not be able to turn on with such a large gate resistor.
