- 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.

*Note: Mode B
is compliant with California Title 24
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. |
