3-Way Installation
For retrofit 3-way installations the mechanical switch needs to be rewired as shown in the diagram below after wiring the
Dual Tech Sensor Switch. Otherwise the 3-way installation will not work as expected. Single-Pole mechanical switches may
also be used in a 3-way with MS-B102, MS-B102-V and MS-B202 models.

1. Connect Ground: Ensure the bare copper or green ground wire from the wallbox is connected to the green ground screw of
the mechanical switch.
2. Tag circuit Common: Your 3-way mechanical switch should have three screw terminals, two of the same color, and one of a
different color. Tag the wire that is connected to the screw terminal of a different color.
3. Identify the wire that matches the color of the wire you connected to the blue wire of the Maestro
R Dual Technology
Occupancy Sensor Switch. Connect this wire to one of the two terminals of the same color.
4. Combine the tagged wire, the remaining wire and yellow jumper wire (included) using a wire connector. Connect the other end
of jumper wire to the different color screw.
