Can I run multiple zones simultaneously?
Yes. OpenSprinkler firmware allows each zone to be set in ‘parallel’ mode, by turning off it’s ‘sequential’ flag. A parallel zone can run at the same time with other zones. The maximum number of simultaneous zones depend heavily on the power capacity of your adapter, and how much current each solenoid valve draws. We’ve tested running 4 to 8 zones simultaneously in lab settings, but the actual number of simultaneous zones has to be determined on a case by case basis.
