Pre-Installation Checklist
- Power Off: Ensure power to your existing sprinkler controller is completely turned off at the breaker.
- Document Wiring: Before disconnecting any wires, take clear photos of your current controller's wiring. This will serve as a crucial reference for connecting wires to your new Skydrop controller. Note which wire corresponds to each zone number and common (C) terminal.

Wiring Your Skydrop Controller
The Skydrop controller features a user-friendly wiring system that does not require a screwdriver for zone connections.

- Feed Wires: Carefully feed your sprinkler zone wires and the common (C) wire through the opening at the bottom of the mounting bracket.
- Connect Wires: Insert each stripped wire end into its corresponding terminal on the mounting bracket. The common wire typically goes into the 'C' terminal, and zone wires go into numbered terminals (1-8). Refer to your pre-installation photos.
- Connect AC Power: Plug the AC power adapter's small connector into the designated port on the mounting bracket.
- Attach Head Unit: Align the Skydrop head unit with the mounting bracket and firmly snap it into place.
