Run the Landscape Wire (Not Included)

The landscape wire should run from the transformer to each light without being cut. Do not run the landscape wire within 10 feet (3m) of a pool, spa or fountain. If the landscape wire is too long, cut it with a cable cutter.

The landscape wire should be protected by routing it close to proximity of the light fixture or next to a building, deck or fence. Use cable suitable for low voltage landscape lighting.

See chart below for recommended cable gauges.

*Suitable cable should be sized in accordance to the table, should be Type SPT-2W. If you cannot find this cable at your local hardware or home improvement store then please call customer service at 1-888-867-6095 or e-mail at [email protected] to order the cable needed.

How to setup the transformer for your lighting system

Current time & date setting

This step is needed for the lighting modes Auto, Timer and Sunwise to work properly or else they won’t open/close at the right time.

1. Press both MODE and ENTER at the same time quickly.
2. Use UP and DOWN to select the date and ENTER to confirm. Apply the same procedure for the current time.

Location setting (for Sunwise mode only)

Sunwise is a feature that does not need a photocell to operate. Thanks to that, it can be installed indoor and it will still open the lights from dusk to dawn, following the seasons. All it needs is your local time and location to calculate the sun’s position to estimate your local dusk/dawn time. Here is how to set it up:

1. Press MODE and UP at the same time quickly.
2. According to the map at step #6, enter your location by selecting one of the three following options and pressing ENTER to confirm (if you live in Canada, select “North”):

4. END time settings – ONLY FOR AUTO, TIMER AND SUNWISE LIGHTING MODES. Choose one of the two END time option:
   • a) Dawn END time: select this option to make the lights close at dawn automatically every day. It will use the photocell if you selected the mode Auto and your location if you selected Sunwise. Scroll the hours until you see the DAWN icon and press ENTER to select it.
   • b) Fixed END time: select this option if you want the transformer to close the lights every day at the same hour. This type of END time will not adjust to the seasons, be it summer or winter, the END time will stay the same. To select this option, simply select the END time wanted.

Troubleshooting

All of the lights fail to work

• If the LOAD icon is flashing, make sure you are using less than 300 watts. If necessary, remove some fixtures and change the lighting mode to the desired one after.
• Check that the transformer power is on.
• Check if there is a loose connection at the transfomer screw terminal.
• Check that the current mode is not set to «OFF».

The lights are “ON” during the day

• The power unit is in a dark area which triggers the photocell to turn ON the lights.

The lights do not switch “ON” at dusk

• The power unit is in a area where there is too much light at night.

The lights are not turning on after selecting Timer or Sunwise mode.

• Timer and Sunwise mode only open up at their exact start time setting (Start for timer and dusk for Sunwise). Ex: if it is 8 PM at your location and you set the start time to 7 PM, the channel won’t turn on until 7 PM the next day.

There is a significant delay in Sunwise mode.

• Make sure that you selected the right zone. If you live far to the north, or far to the south, Sunwise may not be optimal.

Maintenance

• To clean, wash with a damp soft cloth.
