LIGHT LEVEL FEATURE
The Light Level feature holds lights off upon initial occupancy if adequate
ambient light exists. It will not turn the lights off if they are on. The default
setting is for maximum, meaning that even the brightest ambient light will not
hold the lights off. When the light level is set it is written to memory so that in
the event of a power failure the setting is not lost.

The sensor enters setup mode, as indicated by the rapidly flashing Red LED.
The LED will flash throughout the setup process. Occupancy indications from
the LEDs are disabled during setup.

The sensor measures the light level for a 25-second period, then averages
the readings and automatically sets the light level function.

default. The Green LED flashes rapidly for 10 seconds after the setting has
