    Hi Brian,
    I searched for the Make and Model number for the combination switch that you are referring to and was unable to locate the information. Brian if the switch has 3-way capabilities it would definitely say so on the box and on the wiring diagram. Most dimmer switches are now made so they can be wired as single switch or as one of the two 3-way switches and this is clearly stated on the packaging.

    I have a Greenheck Model GTD #381194 Fan/Light delay off timer toggle switch that I am trying to install in a 3 way application. The directions only show Fan & Light Combination or a Single Load diagram. Can it be installed for 3 way?
