NOTES:
• Leave wallplate off if custom settings are desired.
• The Dual-Circuit Occupancy Sensing Switch was designed for wiring flexibility. When wiring Circuit 1, you may use either black wire to connect
to the line or load side. When wiring Circuit 2, you may use either black-orange wire to connect to the line or load side.
• Please note that both black wires correspond to Circuit 1, and both black-orange wires correspond to Circuit 2.
• If replacing existing switches with this product, it is recommended that you label the wires AFTER turning power OFF (Step 1), but BEFORE
removing the previously installed switches and proceeding with wiring the Dual-Circuit Occupancy Sensing Switch
