Essential Info

Intermatic EI600C 7-Day Astronomic Electronic In-Wall Timer is easy to program and provides up to 40 ON/OFF operations per week which can be used for 24-hour or 7-day load control. The astronomic feature provides sunset ON and sunrise OFF settings and the auto daylight savings adjustment means you can "set-it and forget-it". The independent 7-day programming provides complete flexibility for applications where load switching differs each day of the week. The timer has an isolated single pole single throw switch which allows the timer to switch any load type. A 3 wire design allows the timer to be replaced, or be used as a single-pole or 3-way (multi-way) switch.

    We bought all kinds of Electronic timers from Smarthome , Home Depot, and Lowes Most customers compliant and it hard to program and see the digtaal reading The best one to use and simple program use GE not Intermatic KM2ST-1G In-Wall 24 Hour 20A SPST Mechanical Timer the motor will not last after three to six months Same model user GE wall timer last longer is the good ones
    DONALD -- columbus, OH   1/22/2012
    Timer was fairly easy to install with no unexpected problems. It functions perfectly. When programming, each on time and each off time require a separate program number. For example, the first on time should be program 1, and the first off time should be program 2. This was not all that clear in the instructions.

    This switch is exactly what I have been looking for. The instructions were very straight forward and the switch performs exactly the way I expected. It was a good price too except for the excessive shipping costs!
