Two-Location Applications Using an Existing Switch
SETTINGS
The user has the ability to use an existing 3-way mechanical switch as their second location control. This allows the
lights to be controlled from a second location after a simple rewire of the existing switch. Additional programming is
required to work with a mechanical switch and can be found on page 20. If Companion Dimmer(s) are used for a 3-way
application, the default setting requires no change.
