How do I Wire a 120-Volt Intermatic Pool Pump Timer?
Running a pool pump constantly is often unnecessary and can cause early failure of the pump. It's better for the pump, and your energy bill, to run it intermittently. An Intermatic timer is a convenient and easy-to-install device that will turn your pool pump on and off automatically at set times of the day. You can easily set the timer using color-coded pins inserted into the timer's clock face. Once set, the Intermatic timer will cycle the pump on and off without any further action on your part. Does this Spark an idea?
