Why are there two multi-way traveler wire connections on each switch?
When using multi-rocker faceplates, it is possible to hard-wire a 3-way circuit for both the load controlling switch and the 2 nd “transmit-only” switch. It is also possible to use a dual rocker faceplate (model ZS12) with a USR Dedicated Remote Switch Base, thereby allowing two remote switches in a single-gang box. Please refer to the SimplyBrilliant user guide for wiring diagrams.
