Setup and Installation
- Choose a Mounting Location: Select a sturdy, vertical surface near a 120V AC outdoor power outlet. The transformer is designed for wall mounting and is heavy; ensure the mounting surface can support its weight. Consider using the provided bracket and securing it to a wall stud or using appropriate wall anchors.
- Mount the Transformer: Securely attach the transformer to the chosen location using appropriate screws and anchors. Ensure it is level and stable.
- Connect Low Voltage Wires: The transformer features two terminals for independent control of two lighting zones. Connect your low voltage landscape lighting wires to the designated terminals (Zone 1 and Zone 2). Ensure all connections are tight and secure. Do not exceed the total wattage capacity of 200W, and ensure each zone's load does not exceed 80% of the total capacity.
- Position the Photocell Sensor: The photocell sensor is removable and comes with a 6-foot UL cord. Position the sensor in an area that receives natural light, away from artificial light sources that might interfere with its operation (e.g., porch lights, streetlights). This ensures accurate dusk/dawn detection.
- Plug into Power: Once all connections are secure and verified, plug the transformer's 120V AC power cord into a grounded outdoor outlet.

Maintenance
- Cleaning: Periodically wipe the transformer's exterior with a soft, damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents.
- Photocell Sensor: Ensure the photocell sensor remains clean and unobstructed for accurate light detection. Clear any leaves, dirt, or snow that may cover it.
- Connections: Annually inspect all wiring connections to ensure they are tight and free from corrosion.
- Weather Protection: Although weatherproof, it is recommended to install the transformer in a location that offers some protection from direct, prolonged exposure to extreme weather conditions to extend its lifespan.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights are not turning on. | No power to transformer, loose connections, circuit breaker tripped, incorrect mode setting, faulty lights. | Check power outlet. Ensure all low voltage wires are securely connected. Reset the built-in circuit breaker (if tripped). Verify the operating mode and settings. Test individual lights. |
| Timer/Photocell not working correctly. | Incorrect time/date setting, photocell obstructed, photocell faulty, incorrect mode selected. | Re-set current time and day. Ensure photocell is clean and unobstructed. Verify the correct operating mode is selected for the desired function. |
| Circuit breaker trips frequently. | Overload (total wattage exceeds 200W), short circuit in wiring or lights. | Reduce the total wattage of connected lights to below 80% of 200W. Inspect wiring and light fixtures for any damage or short circuits. |
| Lights flicker or are dim. | Loose connections, insufficient wire gauge for distance, too many lights. | Check all connections. Ensure appropriate wire gauge is used for the length of the cable run. Reduce the number of lights if exceeding capacity. |
