0-10V In-Wall Toggle Smart Dimmer with QuickFit and SimpleWire enhancements. Revolutionary QuickFit design features a housing depth that is up to 20 percent smaller than the previous Z-Wave models. This reduced size coupled with the elimination of heat taps provides a better fit in older style boxes and multi-gang configurations. SimpleWire technology allows line and load to automatically be configured with auto-sensing line-load terminals. This device includes low voltage wiring designs for use with 0-10V commercial lighting. All of this is coupled with Z-Wave S2 and SmartStart allows for effortless installation while being safer than ever!
