5. Installation
Follow these steps for proper installation of your landscape transformer:
- Choose a Location: Select a suitable outdoor location for mounting the transformer. It should be mounted on a vertical surface, such as a wall or post, between 12 inches (0.3m) and 48 inches (1.2m) from the ground. Ensure the location allows for easy access to the power outlet and the low voltage wiring.
- Mount the Transformer: Use appropriate screws (not included) to securely mount the transformer through its built-in hanging holes.
- Connect Low Voltage Wires: Connect the positive and negative wires from your 12V landscape lights to the terminal blocks on the transformer. Ensure a secure connection for each wire. The transformer provides two terminal output ends; choose one to connect your lights.
- Connect Photocell Sensor: Plug the photocell sensor into its designated port on the transformer. Position the sensor where it can accurately detect ambient light (dusk/dawn) without being obstructed or exposed to direct artificial light sources at night.
- Plug into Power: Once all low voltage connections are made and secured, plug the transformer's 3.3ft SJTW18AWG3/C power cord into a standard 120V AC outdoor-rated electrical outlet.

6.1 Setting the Clock
Press the 'CLOCK' button to enter clock setting mode. Use the arrow buttons to adjust the hour and minute, then press 'CLOCK' again to confirm.
6.2 Selecting Operating Modes
Press the 'MENU' button repeatedly to cycle through the following operating modes:
- MANUAL ON/OFF: Lights can be manually turned on or off using the 'ON/OFF' button.
- Dusk on to Dawn off: The photocell sensor automatically turns lights on at dusk and off at dawn.
- Dusk on to Countdown off (after 2/3/4/6/8 hrs): Lights turn on at dusk and automatically turn off after a selected duration (2, 3, 4, 6, or 8 hours). Use the arrow buttons to select the desired countdown time.
- Dusk on to Timer off: Lights turn on at dusk and turn off at a specific time you set. Use the arrow buttons to set the desired turn-off time.
- Timer on to Timer off: Lights turn on and off at specific times you set, regardless of ambient light. Use the arrow buttons to set both the turn-on and turn-off times.

6.3 Memory Function
The transformer includes a memory function that retains your last selected mode and settings even after a power outage. This eliminates the need for frequent readjustment.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your DEWENWILS landscape transformer.
- 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 dusk/dawn detection.
- Connections: Annually inspect all low voltage wire connections to ensure they are tight and free from corrosion.
- Weather Protection: While weatherproof, avoid submerging the unit in water. Ensure the cover is securely closed if applicable.

8. Troubleshooting
If you encounter issues with your transformer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power to transformer, loose connections, photocell obstructed, incorrect mode, overloaded circuit. | Check power outlet. Ensure all wire connections are secure. Clear any obstructions from the photocell sensor. Verify the operating mode is correctly set. Reduce the total wattage of connected lights if exceeding 200W. |
| Lights stay on/off constantly. | Photocell sensor issue, incorrect mode, timer settings incorrect. | Ensure photocell is clean and not exposed to artificial light at night. Check that the correct operating mode (e.g., Dusk to Dawn) is selected. Verify timer settings are accurate. |
| Transformer displays "FAIL" or shuts off. | Overload or short circuit detected. | Disconnect all lights from the transformer. Check each light and wiring for shorts or damage. Reconnect lights one by one to identify the faulty component. Ensure total wattage does not exceed 200W. |
