Turn your lights and appliances on and off, even if you're not there! The Leviton In-Wall LCD Timer is a programmable, electronic timer switch that permits 24-hour ON/OFF scheduling in 30-minute intervals, up to 48 per day. Yet you'll still have complete manual ON/OFF control via the buttons just below the easy-to-read, backlit LCD screen. Note that the Leviton LCD Timer does not work in a three-way switch configuration.# Leviton In-Wall LCD Timer # Instructions # Mounting materials. Designed for easy installation in single and multi-gang wall boxes, the Leviton In-Wall LCD Timer's contemporary styling complements fine dcor and coordinates with other Decora-style switches, dimmers and faceplates. And unlike non-electronic timers, this one has no unsightly knobs, no moving parts to break, and no rotary wind-up ticking noise. The Leviton In-Wall LCD Timer is ideal for programming landscape lighting, making your house look occupied when you're not home, making sure the front porch light is on when you come home each night, whole-house exhaust fan scheduling, and more. It even features programmed back up in the event of a power failure. Also available in white or ivory (sold separately), each unit features an impact-resistant thermoplastic face and quality construction for long service life and superior performance. Please note that the neutral wire is required for installation of this product.
