5. Setup and Installation

Follow these steps for proper installation of your low voltage transformer:

1. Choose a Location: Select a suitable outdoor location near a 120V AC GFCI (Ground Fault Circuit Interrupter) outlet. The transformer should be mounted vertically on a wall or post, at least 1 foot (30 cm) above ground level. Ensure the photo sensor is not obstructed and receives ambient light.
2. Mount the Transformer: Use appropriate screws and anchors (not included) to securely mount the transformer to the chosen surface using the two hanging holes on the back.
3. Route the Low Voltage Cable: Lay out the 100FT 16 gauge lighting cable from the transformer to your landscape lighting fixtures. Ensure the cable is routed safely, avoiding areas where it could be cut or damaged. You can bury the cable a few inches deep or conceal it under mulch.
4. Connect Lighting Fixtures: Connect your low-voltage landscape lights to the 16 gauge cable. Most low-voltage lights use quick-connectors or require stripping the wire ends and securing them with wire nuts or terminal blocks. Ensure all connections are secure and waterproof.
5. Connect to Transformer: Strip approximately 1/2 inch of insulation from the ends of the 16 gauge lighting cable. Insert the bare wires into the output terminal on the bottom of the transformer and tighten the screws to secure the connection. Ensure no stray wire strands are touching.
6. Plug In: Once all connections are made and secured, plug the transformer's power cord into a 120V AC GFCI outlet.

4. Use the TIMER ON and TIMER OFF buttons to adjust the minutes.
5. Press CLOCK one more time to save the setting.

Operating Modes

The transformer offers six operating modes, selectable via the dial on the control panel:

• 1. ON: The transformer is continuously on. Lights will remain on regardless of time or light conditions.
• 2. OFF: The transformer is continuously off. Lights will remain off.
• 3. AUTO: This mode utilizes the photo sensor. Lights will turn on automatically at dusk and turn off at dawn.
• 4. TIMER ON / TIMER OFF (Clock Control):
  • Set the desired ON time using the TIMER ON button (hour and minute).
  • Set the desired OFF time using the TIMER OFF button (hour and minute).
  • The lights will turn on and off according to your set times.
• 5. DUSK + 4/6/8/10 Hours:
  • The photo sensor will detect dusk and turn the lights on.
  • The lights will then automatically turn off after 4, 6, 8, or 10 hours, depending on your selection on the dial.
• 6. PHOTO CELL TEST: This mode allows you to test the functionality of the photo sensor. The lights will turn on briefly to confirm the sensor is working.

To select a mode, rotate the dial on the control panel to the desired setting.

7. Maintenance

• Cleaning: Periodically wipe the transformer housing with a damp cloth to remove dirt and debris. Do not use abrasive cleaners or immerse the unit in water.
• Photo Sensor: Ensure the photo sensor is clean and free from obstructions (e.g., leaves, dirt) to guarantee accurate dusk-to-dawn operation. The sensor is replaceable if it becomes faulty.
• Cable Inspection: Regularly inspect the low-voltage cables for any signs of damage, cuts, or fraying. Repair or replace damaged sections immediately to prevent electrical hazards.
