Installatie

Disconnect power; wire the color coded receptacle according to the diagram below. Push the photocontrol on and twist it clockwise to lock it into the receptacle. Adjust the receptacle position if necessary, to ensure the Photocell facing the NORTH direction as indicated on the top of the photocontrol.

• To test “turn on” during daytime, cover its eye with opaque material.
• Do not cover with finger because light traveling through fingers may be great enough to keep the Photocontrol off.
• photocontrol test will take approximately 2 minutes.

* Operation of this Photocontrol is not affected by weather, moisture or temperature changes.
