3. Disconnecting the Controller Module:
- Once the housing is open, perform a visual inspection for any signs of water damage or corrosion.
- The timer module is connected via a 16 to 20 pin ribbon cable. Gently pull this cable out to disconnect the module.
- Remove the timer module itself. Note that the two snap-in hinges remain with the gray case.
3. Removing the Terminal Wiring Board:
- Before removing the terminal board, it is critical to turn off power to the unit at your circuit breaker panel.
- Identify the four Phillips head screws that secure the terminal wiring board. Use a Phillips screwdriver to loosen and remove these screws.
- Important: Take a digital photo or label all wire connections before disconnecting them to ensure correct reinstallation.
- Carefully disconnect the 24 Volt AC (VAC) connections. To isolate these wires, you can either:
- Apply electrical tape to the copper ends.
- Use electrical nuts to cap the ends.
Operating the Controller
The Irritrol Rain Dial RD1200-EXT-R features an intuitive interface for programming and managing your irrigation schedules. Refer to the quick reference card or the full user guide for detailed programming steps.
Basic Operation:

- Adjusting Run Times: Set specific run times for each station within your programs.
- Seasonal Adjustments: Leverage the Climate Logic readiness to automatically adjust watering based on local weather conditions, optimizing water usage.
- Manual Operation: The controller supports manual operation for immediate watering needs.
