Hi. I will be hooking up my 9-zone (+1 master valve) irrigation system to a 16-zone Iro soon. I have:
- wire for master valve
- wire for each zone (1-9)
- a single common wire
- two wires from external rain sensor
Looking at this diagram, it’s pretty clear where everything goes except for the common wire. Can I plug in my single common wire to the left common terminal (while still using zones 1-9), or will I have to put a pigtail on my common wire so that I can connect my single common wire to both common terminals on the Iro?
