4. Setup and Installation
4.1 Mounting the Controller
Choose a suitable indoor location away from direct sunlight, heat sources, and moisture. Use the provided mounting hardware to secure the controller to a wall.
4.2 Wiring the Controller
Follow these steps for proper wiring:
- Power Connection: Connect the 24V AC output from the transformer to the terminals labeled "24VAC" on the controller.
- Valve Wiring: Connect one wire from each solenoid valve to its corresponding station terminal (e.g., "1", "2", "3", etc.). Connect the common wire from all solenoids to the "C" (Common) terminal.
- Sensor Connection (Optional): If using a rain or soil sensor, connect it to the "SEN" terminals.

5.2 Programming Watering Schedules
The Eco Logic controller offers two independent programs (Program A and Program B). Each program can have up to 4 start times.
- Setting Start Times: Navigate to "Start Times" on the display and use the buttons to set the desired start times for each program.
- Setting Run Times: Navigate to "Run Times" and set the duration for each station within the program. Each station can run for up to 4 hours.
- Water Days: Select specific days of the week, odd/even days, or interval watering based on your irrigation needs.
5.3 QuickCheck Technology
The integrated QuickCheck technology allows for simple diagnosis of potential wiring faults in the irrigation field. It helps detect and troubleshoot issues efficiently by indicating which station might have a problem.
5.4 Short-Circuit Protection
The system detects wiring faults and, in case of a short circuit, prevents damage to the system at the affected station bridge without affecting the overall operation of the irrigation system. This protects your controller and connected components.
5.5 Seasonal Adjustment / Suspend Watering
The automatic off-season watering suspension feature allows you to program the system to pause watering for up to 7 days. This is useful for seasonal changes, during rainy periods, or when irrigation is not needed.
6. Maintenance
To ensure optimal performance and longevity of your irrigation programmer, follow these maintenance guidelines:
- Regularly check wiring connections for corrosion or damage. Ensure all terminals are securely fastened.
- Keep the controller clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure the power supply is stable and free from fluctuations.
- There are no user-serviceable parts inside the controller. Do not attempt to open the casing beyond accessing the wiring terminals.
7. Troubleshooting
If you encounter issues with your irrigation programmer, refer to the table below for common problems and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power from transformer; faulty transformer; loose connection | Check power outlet; verify transformer output; secure connections. |
| Specific zone not watering | Faulty solenoid; wiring issue to the valve; program error for that zone | Use QuickCheck to diagnose wiring; check solenoid for functionality; verify program settings for the specific zone. |
| System short circuit detected | Wiring fault in a station or common wire | Identify and repair the wiring fault using QuickCheck. Isolate the problematic station. |
| Difficulty programming | User unfamiliarity with interface or sequence | Refer to the "Operating Instructions" section (Section 5) and follow the steps carefully. Practice setting programs. |
