 Operational settings can be changed via the push-button sequence outlined below (note the example used is for changing occupancy time delay). Programming for 2P units done with each 

pole’s  corresponding push-button.

e.g., 5 flashes is default

10 min time delay

e.g., press 4x 
    to change 

      to 7.5 min

e.g., 4 flashes 
indicates new 

7.5  min time

=  On Mode

Automatic On turns lights on when occupancy is detected. Manual 

On requires a button press to turn the lights on. Reduced Turn-On 

directs the sensor to only turn on when a large motion, such as 

a person entering a room, is detected. Weaker signals, such 

as reflections from glass, are ignored. Once lights are on, the 

sensor returns to maximum sensitivity.

•  Default for units with -SA, -VA, or -NL option: Manual On

•  WSX (PDT) 2P Series default: Pole 1 Auto On, Pole 2 Manual 

•  Default for 2P units with -2SA, -2VA, or NL options: 

      Both poles Manual On

=  Switch Modes

These modes dictate switch functionality. 

Pressing the button in Override Off mode (setting 1) turns off 

and keeps lights off until pressed again. 

Disabling the Switch (setting 2) prevents the button from turning 

the lights on. (continued next column) 

Predictive Mode (setting 3) determines if a user has left the room 

after the lights are switched off. It does this by monitoring the 

space for a period after the button is pressed (Predictive Grace 

Time), following a delay to allow exiting the room (Predictive Exit 

Time). If occupancy is detected the device will disable Auto-On 

& hold the lights off until manually switched. If no occupancy is 

detected the sensor instantly reverts to auto-on mode.
If Predictive Mode with Expiration (setting 4) is enabled, once 

the sensor has disabled Auto-On it will continue to monitor the 

space. When no occupancy is detected for a duration equal to the 

occupancy time delay, the sensor will revert to Auto-On mode.
