2. Safety Information
Please read and understand all instructions before installing or operating this transformer. Failure to follow these instructions may result in electric shock, fire, or other hazards.
- Electrical Safety: Always disconnect power at the circuit breaker before installing or servicing the transformer. Ensure the transformer is connected to a Ground Fault Circuit Interrupter (GFCI) protected outlet.
- Outdoor Use: This transformer is designed for outdoor use. Ensure all connections are waterproof and protected from moisture.
- Mounting: Mount the transformer at least 1 foot (30 cm) above ground level to prevent water damage.
- Wiring: Use only low voltage landscape lighting cable (e.g., 12-gauge, 14-gauge, or 16-gauge) suitable for direct burial or outdoor use. Do not exceed the maximum wattage capacity of the transformer (400W or 500W). Optimal use should not exceed 90% of the maximum power.
- Overload Protection: The transformer includes built-in circuit protection. In case of a short circuit or overload, the power will automatically cut off to protect your lights.
- Photocell Sensor: Ensure the photocell sensor is not obstructed by objects or light sources that could interfere with its operation.
3. Product Features
The HIBOITEC Low Voltage Landscape Transformer is equipped with several features to enhance your outdoor lighting experience:
- Dusk-to-Dawn Photocell Sensor: Features a removable and replaceable photocell sensor that automatically turns lights on at dusk and off at sunrise, optimizing energy consumption. The upgraded sensor provides zero-delay current output upon detecting darkness.
- Overload Protection: Built-in anti-high voltage automatic circuit breaker protects your lighting system by cutting power during short circuits or overloads.
- Memory Function: Retains your last set mode even after a power outage, eliminating the need for frequent readjustment.
- Multiple Timing Functions: Offers various modes including Automatic ON/OFF, Dusk ON/Timer OFF, Timer ON/OFF (ON and OFF at set times), and Test mode.
- Weatherproof & Durable: Constructed with a high-quality metal shell (Heavy Duty 304 Stainless Steel) that is windproof, waterproof, dustproof, corrosion-resistant, and anti-rust, ensuring a long service life.

4. Setup and Installation
Follow these steps for proper installation of your HIBOITEC landscape transformer:
- Choose a Location: Select a suitable outdoor location near a 120V AC GFCI-protected outlet. The location should be protected from direct water spray and allow for proper ventilation. Mount the transformer at least 1 foot (30 cm) above ground level.
- Mount the Transformer: Securely mount the transformer to a wall or post using appropriate hardware (not included).
- Connect Low Voltage Cables: Strip approximately 1/2 inch (1.2 cm) of insulation from the ends of your low voltage landscape lighting cables. Connect the cables to the low voltage output terminals on the transformer. The transformer provides 12V and 15V AC output terminals. The 15V output compensates for voltage drops on longer wire runs. Multiple terminals are available for several wire runs. Ensure a secure connection.
- Install Photocell Sensor: The photocell sensor is typically pre-installed or can be easily attached. Ensure it is positioned where it can detect ambient light without obstruction from artificial light sources or shadows.
- Plug In: Once all low voltage connections are secure and verified, plug the transformer's power cord into the 120V AC GFCI-protected outlet.

5. Operating Instructions
The HIBOITEC transformer offers various operating modes controlled via its integrated display and buttons (MENU, Up, Down, ENTER).
5.1 Setting the Clock
Refer to the display for current time. Use the MENU button to navigate to the clock setting, then use Up/Down to adjust hours and minutes, and ENTER to confirm.
5.2 Operating Modes
Press the MENU button to cycle through the available operating modes:
- Manual ON/OFF: Lights can be manually turned on or off. This mode bypasses automatic functions.
- Photocell Auto ON/OFF (Dusk to Dawn): The photocell sensor detects ambient light. Lights will automatically turn on at dusk and turn off at dawn.
- Dusk ON/Timer OFF: Lights turn on at dusk (detected by the photocell) and remain on for a set duration (e.g., 4, 6, 8 hours) before turning off.
- Timer ON/OFF: Allows you to set specific ON and OFF times for your lights, independent of ambient light conditions.
- Test Mode: A short mode to test the functionality of the lights and settings.
Use the Up/Down buttons to adjust settings within each mode (e.g., timer duration, specific ON/OFF times) and ENTER to confirm your selections.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your transformer:
- Cleaning: Periodically wipe the transformer's exterior with a damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents.
- Photocell Sensor: Ensure the photocell sensor lens is clean and free from obstructions (e.g., leaves, dirt, snow) that could affect its light detection.
- Cable Inspection: Annually inspect all low voltage cables for damage, fraying, or exposed wires. Repair or replace damaged cables immediately.
- Connections: Check terminal connections periodically to ensure they remain tight and secure.
