- A Momentary logic 1 causes On condition and starts Auto operation. 15 seconds after Auto operation times out, Auto operation terminates.
- A momentary logic 0 causes Off condition.
- A momentary logic 1 causes On condition and starts Auto operation.
- A momentary logic 0 terminates Auto operation and causes Off condition. After 8 seconds, Auto operation resumes.

|
Wall switch sensors are adaptable to 3-way operation
with a remote switch.
|
|
Ideal for wall and ceiling mounted occupancy sensors
providing energy savings and convenience.
