Intermatic Digital Self-Adjusting TimerDarkened and unoccupied homes can be irresistible to burglars. Protect your home and the valuables inside when you are away with the Intermatic self-adjusting timer. With easy to use controls and set-up you can have a lamp TV or stereo turn on and off at specific times to make it look like someone is home even when the house is empty in just minutes. The time can be programmed with up to 7 different on/ off cycles and with the manual override you can turn on the connected device on at any time.
