Tips To Optimize Photocell Performance


Do not face the photocell into the midday sun. If the photo control is installed on the south side of a building, face the photocell east or west or point the photo control down toward the ground.  The best direction to face the photo control is north. 

Do not face the photocell where it can see artificial light. Light from windows, signs, street lights, etc., will cause the photo control not to switch on.  The photo control should not be positioned so that it sees the light it is controlling (or reflected light - like off of your white siding or white painted soffit overhang).  These conditions will cause the light to cycle on and off.

Do not install the photo control with wires up unless there is NO POSSIBILITY of water entering the photo control around the wires. The photo control must be installed in an approved weatherproof box. Do not attempt to caulk around the wires. Installing a Photocell below the box is WRONG! Photocells installed on top of the Box is RIGHT! Any Photo Control installed by the side of the weatherproof box is: ACCEPTABLE!

When you are testing the photocell, be sure to turn on the power (load will come on) and wait up to 5 minutes for the photocell to switch load off. For further testing cover the photo control completely with black tape or another dark material to simulate night conditions. If you cant cover the control with tape, try covering the photo control with the shipping carton to simulate night conditions.
