How do I find my Model Number?
Do you have the original packaging?
-
If your product came in plastic packaging (a clamshell), you’ll find the model number on the front of the insert card, on the lower left corner. If your product came in a box, you’ll find the model number on the top of the box.
Most model numbers are 12-16 characters and start with a couple letters followed by a dash.
No packaging? No problem!
-
The product number is on a label on the side of the dimmer or switch.*
If you’ve already installed the dimmer/switch, turn off the electricity and then remove the wallplate. Unscrew and remove the wallplate adapter, then unscrew the dimmer/switch and pull it out of the wall until you can see the label.
*Please note: The product number for Ariadni/Toggler dimmers is not on a label. It’s located directly on the front of the dimmer on the top left, or right below the on/off toggle.

Do I need a companion dimmer for multi-location dimming and switching?
Not always, as it depends on the model number. Some products, such as the Maestro C·L dimmer, will work with a standard mechnical switch in a 3-way application. Other models may require a master and a companion device. Note: In a 4-way application, companion devices are always required.
