I have a RM HD-12, which has been running 9 zones. There are 2 cables running from the HD-12 to the valve boxes - one with 7 wires and one with 5 wires. Those 12 wires consisted of the 9 zones, 2 white common wires and 1 unused. There is no master valve.
Recently, my irrigation contractor added a 10th zone to my lot. As I understand things, he freed up 1 of the 2 common wires by adding a common shunt wire in the valve box. Inside the HD-12, one white wire is connected to one of the two Common terminals. The other white wire is now connected in the HD-12 as Zone 9, and the former Zone 9 wire has been moved to terminal #10 in the HD-12 to become Zone 10.
My question is this. The Zone lists in my Programs now start with Zone 10 listed first, followed by Zones 1 through 9 listed in numerical order. When the Program is run, Zone 10 runs first, followed by Zones 1 through 9 in order. Why is Zone 10 listed and running first? It is my shrub/drip zone, which I would like to run last.
