About This Revolutionary, patent-pending design – QuickFit and SimpleWire technologies offer groundbreaking home automation features. Unique advancements make the smart controls easier to install and more reliable than ever. QuickFit – Improved components reduced the housing depth by up to 20% compared to previous Z-Wave models and eliminated the need for heat tabs. QuickFit enhancements are the ideal smart solution for older-style switch boxes, multi-gang configurations or any other application with limited space. SimpleWire – Auto-detecting line/load terminals support fast installation by identifying line and load wires and configuring the dimmer accordingly. Dual ground ports, which are offset to avoid switch box mounting screws, support daisy-chaining in multi-switch setups.
