Hi,

I have 7 zones in my system but I could only find 6-zone wire at my local Home Depot. So, I bought 4-zone wire and ran two strands to my garage for the controller. My question is: Should I connect the two white "common" wires from each strand together and then to each valve, or should I connect one wire's common to, say, four valves and the other wire's common to the other three valves? Does it matter?

Thanks!
