Observed: colors at controller aren't identical to colors at values in every case. I remember that the installers shorted us cable and I had to augment with a new length whose colors were different. Aberrant in particular: red, green and grey. Therefore, somewhere these connect and some mappings are done, but it's no longer possible to discern.
The Orbit controller offered 12 zones.
| Zone | Wire color | Description |
|---|---|---|
| 0 | white | Common wire—goes to every valve |
| 1 | red | Front parkway and central lawn sprinklers |
| 2 | purple | South (garage) and front parkway (mailbox) |
| 3 | green | North: back lawn, side and front lawn (north of steps) |
| 4 | black | Lawn under deck |
| 5 | grey | Back bottom |
| 6 | blue | Big front plantings microsprays |
| 7 | yellow | South microsprays |
| 8 | orange | Back planter, back hedge and back down-hill microsprays |
| 9 | brown | Back yard bottom (unirrigated) |
