How To Set An Intermatic Wall Timer

Wall-mounted light timers replace the standard switch that is used to operate lights. These devices, including the Intermatic wall switch timer, can be used for many purposes, but the most common use is for security when no one is at home. Instead of wasting electricity by turning on the lights before you leave for the day, the Intermatic wall timers can be set to turn your lights on and off at specific times.

Step 1

Erase all previous timer settings by sliding the control lever left to the "Off" position. When the red indicator light shuts off, the settings are erased. This takes approximately 20 seconds.

Step 2

Move the control lever to the "On" position. The red indicator light will start blinking.

Step 3

Turn the time dial clockwise until you reach the half hour that is closest to your present time. The time dial is set in 30-minute increments.

Step 4

Press the time dial to set the present time. The indicator light will turn off.

Step 5

Twist the dial clockwise until the you reach the first "On" setting, and press the time dial to set the timer.

Step 6

Set the first "Off" time by rotating the dial clockwise until you reach the desired time and pressing the dial.

Step 7

Repeat Steps 5 and 6 until all settings are programmed into the wall timer.

Step 8

Rotate the time dial clockwise once all of the timer settings are programmed until the red indicator light comes on. When the red light is on, the wall timer is in "Automatic" mode, and it will control your lights based on the programmed times.
