5. Setup and Installation
Follow these steps for proper installation of your SUNVIE transformer.
5.1 Mounting the Transformer
Choose a suitable location for mounting the transformer, ideally near a 120V AC power outlet and within reach of your landscape lighting cables. Ensure the location allows for proper ventilation and is protected from direct water accumulation.

Transformer dimensions and mounting points for wall installation.
- Mark the desired mounting points on the wall using the transformer's mounting holes as a template.
- Drill pilot holes if necessary and insert wall anchors.
- Secure the metal mounting bracket (if included) to the wall using the provided screws.
- Hang the transformer onto the secured metal bracket.
5.2 Wiring the Landscape Lights
The transformer features 4 terminal output ends (two 12V and two 14V) and a common (COM) terminal. The 14V output is useful for longer cable runs to compensate for voltage drop.

Detailed view of the terminal block for connecting low voltage wires.
- Strip approximately 1/2 inch of insulation from the ends of your low voltage landscape lighting wire.
- Connect one wire from your lighting system to a 12V or 14V terminal and the other wire to a COM (common) terminal. Ensure a secure connection by tightening the screw terminals.
- Repeat for additional lighting zones if desired, using the remaining terminals.
- Ensure all connections are tight and free from loose strands to prevent short circuits.
5.3 Connecting the Photocell Sensor
The removable photocell sensor allows for automatic dusk-to-dawn operation.

The photocell sensor and its connection point. Ensure the sensor is placed away from artificial light sources.
- Align the sensor connectors of the photocell sensor with the corresponding port on the transformer.
- Twist to securely tighten the threads.
- Remove the protective cover from the photocell sensor to allow it to function properly.
- Mount the photocell sensor in a location that receives natural daylight and is not affected by artificial light sources (e.g., porch lights, streetlights) to ensure accurate operation.

6. Operating Modes
The SUNVIE transformer offers five distinct operating modes to suit your lighting needs. Use the control panel buttons (MENU, UP, DOWN, ENTER) to navigate and set your preferred mode.

The intuitive control panel for easy operation and mode selection.
6.1 Manual ON/OFF Mode
In this mode, the landscape lights will remain continuously ON or OFF, regardless of daylight conditions or set times. This is ideal for manual control when specific lighting is needed.

6.2 Automatic ON/OFF (Dusk to Dawn) Mode
Utilizes the photocell sensor to automatically turn lights ON at dusk and OFF at dawn. This provides hands-free operation and energy savings.

6.3 Photocell ON/Timer OFF Mode
Lights turn ON automatically at dusk via the photocell sensor and then turn OFF after a set number of hours (e.g., 4H, 6H, 8H, 10H). This is ideal for evening illumination for a specific duration.

6.4 Timer ON/OFF Mode
Allows you to set specific ON and OFF times for your landscape lights. This provides precise control over your lighting schedule.

6.5 Test Mode
A short test mode to quickly check if your lights are properly connected and functioning. The lights will turn on for a brief period and then turn off.

7. Maintenance
To ensure optimal performance and longevity of your SUNVIE transformer, follow these maintenance guidelines:
- Regular Cleaning: Periodically wipe down the exterior of the transformer with a soft, damp cloth to remove dust and debris. Ensure the photocell sensor is clean and unobstructed.
- Inspect Connections: Annually check all wire connections to ensure they are secure and free from corrosion. Tighten any loose terminals.
- Check for Damage: Inspect the power cord, sensor cord, and transformer casing for any signs of wear, cracks, or damage. If damage is found, replace the unit or contact customer support.
- Weather Protection: While the transformer is waterproof, avoid submerging it in water. Ensure it is mounted in a location that allows for proper drainage and prevents standing water.
8. Troubleshooting
If you encounter issues with your transformer, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
