Easy exchange with old timer
Your review: Our previous timer was a model 1101 that was over 27 years old. It slowed down and the off/on trips didn't work. So I bought a new model 1101. It took all of 5 minutes to replace.The new one works great!
Pros: Easy installation and interchange of old and new timers. Also, I called the help line and they explained how to "pinch out" the old mechanism.
