Essential Info

The Intermatic EJ500 Astro Electronic In-Wall Timer is a replacement for your standard indoor wall switch with an astronomic feature that will adjust to sunrise and sunset automatically. This in-wall timer provides up to 14 ON/OFF events per week and is compatible with single pole and 3-way installations adding to the ease of use. In addition, the timer can be adjusted for the weekdays without affecting the weekend time schedule. The included randomization feature will make sure the lights do not turn on at exactly the same time every day which increase the security of your home by deterring possible burglars. This feature gives the home a "lived-in" look so it appears that people are home even if they aren't. At any time, the lights can be overridden to turn on and off without interrupting the current set schedule. The battery backup prevents memory loss if power is lost.
