<b>How to Choose Your Transformer</b><br> 1.Calculate the total wattage of your light fixtures in your plan<br> 2.Choose the transformer that is large enough to support the total wattage you need<br> 3.The transformer wattage load (total watts needed for your fixtures) should be within <b>80% </b>of the rated capacity of the transformer. <br> <b>For example: if you have 12 pack 13W landscape lights, so the total wattage is 156W. Then you can choose the transformer higher than 195W(=156W/0.8). </b><br><br><b>Installation Steps</b><br> 1. Conenct the transformer with several landscape lights.<br> 2. Plug it in your control box to power on.<br> 3. If it is "O", the light will work all the time; When you set it to "A"(Auto) or "1-9"(Countdown Timer), it will not turn on at daytime. But you can cover the sensor to test it. When you cover it for over 30S, the sensor will detect it is nightime, then the light will turn on.<br><br> <b>Specifications</b><br> Input: 120VAC, 60Hz<br> Output: 12VAC<br> Max Power Rating: 200W<br><br> <b>Packing List:</b><br> 1 x Transformer<br> 1 x Use Manual<br> 2 x Screw<br> 2 x Wall Anchor<br><br> <b>Tips:</b><br> 1.The dot(at the bottom right corner of the number on the display screen) will light on when it works.<br> 2.The transformer has two outputs with a total power of 200W.
