Setup and Installation
- Mounting: Securely mount the transformer to a wall or suitable vertical surface using appropriate hardware. Ensure it is in a location that allows for proper ventilation and access.
- Power Connection: Plug the transformer into a standard 120V AC outlet.
- Wiring Landscape Lights:
- Strip approximately 1/2 inch of insulation from the ends of your landscape lighting wires.
- Open the clamp-type terminal blocks by pressing down on the lever.
- Insert the stripped wire fully into the desired common (COM1 or COM2) and voltage tap (12V or 15V) terminals.
- Release the lever to secure the wire. Ensure all connections are tight.
- Timer/Photocell Setup:
- The unit includes a timer receptacle and a photocell plug. The digital timer (included) can be plugged into the timer receptacle.
- If using an external photocell (sold separately), remove the jumper from the photocell plug and insert the photocell.

Setting the Timer
- Initial Setup: Follow the timer's specific instructions to set the current time, date, and your geographical location. This allows the timer to accurately calculate local dusk and dawn times.
- Programming On/Off Cycles: Program the desired ON and OFF times for your lighting. The astronomic feature will adjust these times daily based on the changing dusk/dawn schedule.
- Manual Override: Most digital timers include a manual override function to temporarily turn lights on or off outside of programmed schedules.
Refer to the separate instruction sheet provided with the digital timer for detailed programming steps.
Maintenance
- Regular Inspection: Periodically inspect the transformer and wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: Keep the transformer enclosure clean and free of debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure that the transformer's ventilation openings are not obstructed to prevent overheating.
- Circuit Breaker: If the circuit breaker trips, disconnect some lights or check for short circuits before resetting.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights not turning on | No power to transformer | Check power outlet and circuit breaker. |
| Lights not turning on | Faulty wiring connection | Inspect all wire connections at the terminal blocks. Ensure wires are fully inserted and clamped. |
| Lights not turning on | Digital timer not programmed correctly | Review timer instructions and reprogram. |
| Lights flickering or dim | Voltage drop due to long wire runs or too many fixtures | Use the 15V tap for longer runs or reduce the number of fixtures. Ensure appropriate wire gauge is used. |
| Circuit breaker trips | Overload or short circuit | Disconnect some lights. Inspect wiring for shorts. Reset the circuit breaker. |
