Setup
1. Mounting the Transformer
Select a suitable location for mounting the transformer. It must be mounted vertically at least 1 foot (30 cm) above ground level, with the arrows on the unit pointing upwards. Use the provided mounting hole template to mark the drilling points. Secure the transformer to a wall or sturdy surface using the included screws and anchors.

2. Wiring Connections
Ensure the transformer is unplugged from the power outlet before making any connections. The transformer features multi-tap voltage terminals for connecting your landscape lighting wires.
- Identify the common (COM), 12V, and 15V terminals.
- Connect your landscape lighting wires to the appropriate terminals. The 15V terminal is recommended for longer wire runs to compensate for voltage drop.
- The compression-style terminals can accept a maximum of four 10AWG wires. Ensure all connections are secure and tight.
- Verify that no insulation is placed under the terminal plate to prevent fire hazards.

Operating Instructions
The transformer features an intuitive digital display and control buttons for easy operation.
Mode Selection
Use the "UP" (▲) and "DOWN" (▼) buttons to cycle through the available operating modes. The current mode will be displayed on the digital screen.
- 0 = Always On: Lights remain on continuously.
- A = Auto On/Off ("Dusk-to-Dawn"): The built-in photocell sensor automatically turns lights on at dusk and off at dawn.
- 1-9 = Countdown Timer: Lights turn on at dusk and automatically turn off after the set number of hours (1 to 9 hours).
- OFF = Manual Off: Lights remain off.

Photocell Sensor Operation
When in "Auto On/Off" mode, the integrated photocell sensor detects ambient light levels. It will automatically activate your landscape lights when it gets dark and deactivate them when daylight returns.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power to transformer, incorrect mode setting, tripped circuit breaker, faulty wiring, obstructed photocell. | Check power outlet, verify mode (0, A, or 1-9), reset circuit breaker, inspect wiring connections, clear photocell. |
| Lights stay on continuously. | Incorrect mode setting, faulty photocell. | Ensure mode is set to "A" (Auto On/Off) or a countdown timer (1-9). Check photocell for obstructions or damage. |
| Lights flicker or are dim. | Overload, loose connections, voltage drop on long runs. | Reduce total wattage of lights, tighten all wiring connections, use 15V output for longer runs. |
| Circuit breaker trips repeatedly. | Overload, short-circuit in wiring or lights. | Reduce total wattage of lights to below 150W. Inspect all wiring and light fixtures for short circuits. |
