I want to install a timer to control a well pump located at a pond on my property. I've installed a diagram showing the electrical configuration. The thing to focus on is the Bypass Switch (which I use to run the well pump continuously in the Spring to fill the pond). I'd like to replace this with a ST01 timer, but I am unclear what the wiring should be. Also, I have some confusion about the differences I'm seeing in wiring a contactor.
Here is the diagram of the existing configuration:
Here is the current configuration of the Contactor:
Here is what I've seen the ST01 timer wiring should be, timer has black, blue, red, ground wires:
What I don't understand is the difference in the contactor wiring. The wiring in my current configuration works fine. The wiring diagram above shows a jumper from the red hot main feed to a side terminal, which I don't understand. My current configuration has a 2 wire feed to both side terminals of the contactor from a pressure tank switch. Is that not wired correctly? If I were to wire the timer with this jumper would it affect the pressure tank switch wiring? Can I have more than two feeds to a side terminal, each of which only has two blade connectors?
