Digital In-Wall Timer · 7-Day Programmable · 14 ON/OFF Events · White · Intermatic EI500WC
SKU: EI500WC
Intermatic EI500WC is a 7-day digital in-wall timer for 125 VAC single-pole circuits, rated 15A and requiring a neutral connection. It supports up to 14 ON/OFF events, includes random mode and battery backup, and is commonly used for lighting, fans and other scheduled indoor loads.
What this product is for
The Intermatic EI500WC is a digital in-wall timer switch for automating 125 VAC single-pole loads on a 7-day schedule. It is designed for indoor control of lighting and other compatible branch-circuit loads where repeat scheduling, manual override and a wall-switch form factor are required.
Use for
Use for indoor lighting circuits, exterior lights controlled from inside, bathroom fans, holiday lighting, and other compatible loads that benefit from scheduled ON/OFF control. It supports up to 14 ON/OFF events and includes a random mode for occupied-home simulation.
Avoid for
Avoid for 3-way applications unless the installation specifically matches manufacturer instructions, and avoid use where no neutral conductor is present. Do not use beyond the device's electrical ratings or on loads that are not listed as compatible by the manufacturer.
Best for
Best for electricians and maintenance buyers needing a decorator-style wall timer with weekly programming, battery backup and compatibility with incandescent, fluorescent, CFL and LED lighting loads. It is a practical replacement where a standard wall switch location is preferred over a plug-in timer.
Installed in
Typically installed in residential and light commercial wall boxes controlling 120/125V branch circuits. The timer body is approximately 2.75 in H x 1.75 in W x 1.36 in D (about 70 x 44 x 35 mm) and fits a decorator-style wall opening; wall plate is not included.
Why this product exists
This timer exists to replace manual switching with scheduled control for energy management, convenience and basic security lighting routines. Compared with a simple switch, it allows recurring weekly schedules, daylight saving adjustment and temporary manual control without losing programmed events.
Compared with similar products
Compared with mechanical wall timers, the EI500WC offers digital 7-day programming, a backlit LCD display, battery backup and random mode. Compared with basic 24-hour timers, it gives more scheduling flexibility across the week. As a rule of thumb, this style of timer is commonly chosen when weekday and weekend schedules differ. Actual suitability depends on load type, wiring method and local electrical code.
