I installed two Netro Sprites to replace the previous controllers. The installation itself went fine, and I was able to verify that the first one waters the zones fine.

However, the second one does not water any zones. All the status indicators are fine, I hear the water getting turned on, and everything but no watering. What could be wrong? The wiring seems pretty simple. One common wire, 4 zone wires, and the power. All the wires are securely in. What are the ways to troubleshoot this?

Thanks in advance!

Your first Sprite should have a spot for a second common wire.  Maybe try hooking up your second set of zones to that first Sprite then plug in the rest of your sprinkler wires.  I replaced two old digital timers with 1 sprite.  Sorry but that’s my only suggestion good luck.
