5. Setup and Installation

5.1 Mounting the Transformer

Choose a suitable outdoor location for mounting. The location should be near a 120VAC GFCI-protected outlet and allow for the low voltage cables to reach your lighting fixtures.
Ensure the mounting surface is sturdy and can support the weight of the transformer.
Use the provided mounting screws to securely attach the transformer to the wall. The transformer features two mounting holes for easy installation.

5.2 Wiring the Landscape Lights

Ensure the transformer is unplugged from the 120VAC outlet.
Route your low voltage landscape lighting cables to the transformer.
Connect the low voltage cables to the 12VAC output terminals located at the bottom of the transformer. This model features two output zones (12V COM and 12V).
Ensure all connections are tight and secure.

6.1 Selecting Operating Modes

Press the UP or DOWN button to cycle through the available modes:

Photocell ON, Timer OFF (1-9 hours): The lights will turn ON at dusk and automatically turn OFF after the selected duration (1 to 9 hours). The display will show a number from 1 to 9.
Dusk to Dawn (DUSK): The lights will turn ON at dusk and remain ON until dawn. The display will show 'D'.
Always ON (ON): The lights will remain ON continuously. The display will show 'ON'.
Always OFF (OFF): The lights will remain OFF continuously. The display will show 'OFF'.

7. Maintenance

The Tiffcofio Low Voltage Landscape Transformer requires minimal maintenance.

Cleaning: Periodically wipe the exterior of the transformer with a soft, damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents.
Photocell Sensor: Ensure the photocell sensor is clean and unobstructed for accurate light detection.
Connections: Annually inspect all wiring connections to ensure they remain tight and free from corrosion.
Waterproof Integrity: While designed to be waterproof, avoid directing high-pressure water jets directly at the unit.

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 the transformer. Circuit breaker tripped. Incorrect mode selected. Faulty wiring connection. Photocell obstructed or in bright light.	Check the 120VAC outlet and ensure the transformer is plugged in. Reset the internal circuit breaker (refer to Image 5.2) or the household circuit breaker. Verify the operating mode is not 'OFF'. Inspect low voltage wiring for loose connections or damage. Clear any obstructions from the photocell sensor.
Lights stay ON continuously.	'Always ON' mode selected. Photocell sensor malfunction.	Change the operating mode to a timer or 'Dusk to Dawn' setting. Contact customer support if the photocell is suspected to be faulty.
Lights flicker or are dim.	Overloaded circuit. Loose wiring connections. Too many lights connected.	Reduce the total wattage of connected lights to below 100W. Check and tighten all wiring connections. Ensure the total cable length and gauge are appropriate for the load.
