6. Setup and Installation

6.1 Mounting the Transformer

The transformer is designed for secure wall mounting. Use the provided mounting hole template and screws for installation.

1. Choose a suitable outdoor location near a 120V AC GFCI-protected outlet. Ensure the transformer is mounted in a location that protects it from direct water spray and allows for easy access to controls and wiring.
2. Use the provided mounting hole template to mark the drilling points on the desired mounting surface.
3. Drill pilot holes at the marked locations.
4. Securely attach the transformer to the wall using the provided mounting screws.

This image illustrates the physical dimensions (9" H x 5" L x 4.4" W) of the transformer, a mounting hole template for easy installation, and the included 6ft SJTW 18AWG power cord.

6.2 Wiring the Landscape Lights

The transformer features finger-safe, compression-style terminals for connecting low-voltage landscape wiring. These terminals can accept up to four 10AWG wires.

1. Before making any connections, ensure the transformer is unplugged from the 120V AC power outlet.
2. Strip approximately 1/2 inch (1.27 cm) of insulation from the ends of your low-voltage landscape lighting wires.
3. Connect the common wires from your lighting system to the 'COM' terminals.
4. Connect the positive wires from your lighting system to either the '12V' or '15V' terminals. For longer wire runs (typically over 100 feet), using the '15V' terminals is recommended to compensate for voltage drop and maintain optimal light brightness.
5. Ensure all connections are tight and secure within the terminals.
6. Once all wiring is complete, plug the transformer's power cord into a GFCI-protected 120V AC outlet.

7. Operating Instructions

The transformer features an intuitive digital control panel for setting various operating modes.

This image provides a detailed view of the transformer's intuitive control panel, including the digital display and 'UP'/'DOWN' buttons for selecting modes like 'Always On', 'Auto On/Off (Dusk-to-Dawn)', and 'Countdown Timer'.

7.1 Mode Selection

Press the "UP" or "DOWN" button repeatedly to cycle through the available operating modes, which will be displayed on the digital screen:

• 0 (Always On): The connected landscape lights will remain on continuously, regardless of ambient light conditions.
• A (Auto On/Off - Dusk-to-Dawn): The built-in photocell sensor will automatically turn the lights on at sunset and off at sunrise. This mode is ideal for automatic, hands-free operation.
• D (Manual On/Off): This mode allows for manual control of the lights using the ON/OFF button on the control panel.
• 1 through 9 (Countdown Timer): In this mode, the lights will turn on at dusk (triggered by the photocell) and automatically turn off after the set number of hours (from 1 to 9 hours). Select the desired duration by pressing the UP/DOWN buttons.
• OFF: The connected landscape lights will remain off.

The transformer is shown in an outdoor setting with landscape lights, demonstrating how the photocell sensor automatically activates the lights at dusk and deactivates them at sunrise.

7.2 Memory Function

The transformer is equipped with a memory function. In the event of a power outage, the unit will retain its last selected operating mode. No resetting is required once power is restored.

8. Maintenance

The treewell landscape transformer is constructed from durable stainless steel, requiring minimal maintenance to ensure long-term performance.

• Regular Inspection: Periodically inspect the transformer, its power cord, and all connected wiring for any signs of damage, wear, or corrosion. Address any issues promptly.
• Cleaning: Clean the exterior of the transformer with a soft, damp cloth as needed to remove dirt or debris. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the stainless steel finish.
• Photocell Sensor: Ensure the photocell sensor (located on the front panel) is kept clean and free from obstructions such as dirt, leaves, or snow. An obstructed sensor can interfere with proper dusk-to-dawn operation.

9. Troubleshooting

If you encounter issues with your treewell landscape transformer, refer to the following troubleshooting guide:

• Lights not turning on:
  • Ensure the transformer's power cord is securely plugged into a working 120V AC GFCI-protected outlet.
  • Verify that the selected operating mode is not set to 'OFF'.
  • Inspect all low-voltage wiring connections at the transformer terminals and at each light fixture for looseness or damage.
  • Check if the internal circuit breaker has tripped. If so, reset it after identifying and resolving any overload or short-circuit in the lighting system.
  • If using 'Auto' or 'Countdown Timer' modes, ensure the photocell sensor is clean and exposed to ambient light.
• Lights staying on/off at incorrect times:
  • If using 'Auto' or 'Countdown Timer' modes, ensure the photocell sensor is clean and not obstructed by objects, dirt, or shadows that might mimic dusk/dawn conditions.
  • Verify that the correct operating mode is selected on the control panel.
• Lights flickering or dim:
  • Check for loose or corroded wiring connections at the transformer and light fixtures.
  • Ensure the total wattage of all connected lights does not exceed the transformer's 300W capacity. Remove some lights if overloaded.
  • For longer wire runs, ensure you are utilizing the 15V output terminals to compensate for voltage drop.
  • Verify that the light bulbs are compatible with low-voltage systems and are in good working condition.
