have just installed the 3. Zones 1-5 work great. When I removed the old head, it looks like zone 7 has two wires and the second zone 7 went to zone 10. My question is: based on the photo is my zone 8 actually a common wire?
Looking at the picture, it looks like on the
- bottom: two speaker looking wires goes to a rain sensor, the red goes to a Master Valve (or pump), and the white is common
- top: 1-11 with two wires (zones?) hooked into 7. It seems the black terminals indicate common, but nothing seems to be attached
