This is time-consuming, but not difficult. We turn on a zone at the controller in the garage, and then walk around to see what zone is actually running. We do this for each zone, until we have a complete mapping from the old zone numbers to the new zone numbers.
Once we have this table, we can see that to restore the controller to its previous zone definition, we need to
- Switch the wires for 4 and 9
- Switch the wires for 5 and 8
- Move the wire from 6 to 7, the wire from 7 to 10, and 10 back to 6.
