that uses an internal photoconductor cell to measure light
levels. The photocell turns lighting systems OFF when natural

connected to a Synergy analog input or directly to an LPCS
power pack for on/off control.

The deadband feature prevents lighting systems from cycling.
If light levels fall below the set ON level, the LED will be red and
the lights will turn ON when the user-specified time delay has
expired. Light levels will increase until the OFF level is reached.
The user-set OFF level should be twice the electric lighting level
plus 5 percent. If light levels exceed the OFF level, the LED will
turn green and the lights will switch OFF when the time delay
has expired.
