5. Installation

5.1 Mounting the Transformer

1. Select a suitable outdoor location near a GFCI-protected electrical outlet. The transformer is designed for wall mounting.
2. Using the transformer as a template, mark the desired screw locations on the mounting surface.
3. Drill pilot holes and insert wall anchors if mounting into drywall or masonry.
4. Secure the transformer to the wall using the provided mounting screws. Ensure it is firmly attached.

5.2 Connecting Low-Voltage Wiring

1. Route your low-voltage landscape lighting cables from your fixtures to the transformer.
2. Strip approximately 1/2 inch of insulation from the ends of the low-voltage cables.
3. Connect the cables to the appropriate output terminals (12-Volt or 15-Volt) on the transformer. The 15-Volt terminals are recommended for longer wire runs or when using 15-Volt LED fixtures to minimize voltage drop.
4. Ensure all connections are tight and secure.

5.3 Installing the Remote Photocell

1. Connect the remote photocell cable to the designated photocell input port on the transformer.
2. Mount the photocell in a location where it will receive natural daylight and is not obstructed by shadows or artificial light sources (e.g., porch lights) that could interfere with its operation.
3. Ensure the photocell is facing upwards or towards the sky for optimal light detection.

6. Operation

6.1 Control Panel Overview

The transformer features an intuitive control panel with a digital display and four buttons: MENU, UP (▲), DOWN (▼), and OK.

6.2 Setting the Clock

1. Press the MENU button until the 'CLOCK' indicator is lit.
2. Use the UP (▲) and DOWN (▼) buttons to set the current hour. Press OK to confirm.
3. Use the UP (▲) and DOWN (▼) buttons to set the current minute. Press OK to confirm.
4. Ensure the AM/PM indicator is correct.

6.3 Operating Modes

Press the MENU button repeatedly to cycle through the available operating modes:

• MANUAL ON/OFF: Allows you to manually turn the lights on or off. Press OK to toggle.
• PHOTOCELL AUTO ON/OFF (Dusk to Dawn): The lights will automatically turn on at dusk and turn off at dawn, based on the remote photocell's detection.
• PHOTOCELL ON / TIMER OFF: Lights turn on at dusk via the photocell and turn off after a set duration (e.g., 4, 6, 8 hours). Use UP (▲) and DOWN (▼) to set the duration.
• TIMER ON/OFF: Lights turn on and off at specific times you program. Use UP (▲) and DOWN (▼) to set the ON time, then press OK. Repeat for the OFF time.

6.4 Test Function

The 'TEST' function allows you to quickly check if your connected lights are working. When in 'TEST' mode, the transformer will temporarily activate the lights for a short period, regardless of the current time or photocell status. Press OK to initiate the test.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your transformer.

• Cleaning: Periodically wipe the exterior of the transformer with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Connections: Annually inspect all low-voltage wire connections to ensure they are tight and free from corrosion.
• Photocell: Keep the photocell lens clean and free from dirt, debris, or obstructions that could affect its light sensing capabilities.
• Ventilation: Ensure the area around the transformer remains clear to allow for proper airflow and prevent overheating.
