I've come across a used intermatic timer, model ET279C, that I want to use on my pool timer and possible new salt water chlorine generator. My pump is currently set up for 240 volts and wired with a simple disconnect switch. Which wires connect to which terminals on the timer? From what I can tell, the timer has to be wired with 120V for the timer power on terminals 1 & 2. Where do I connect the red and black pump and red and black supply wires? I can't figure it out from the manual diagrams. Also, I don't see anything in the manual about setting the timer for 120V vs 240V, is this automatic, or part of how it's wired to the pump?

Thanks for any guidance and help you can provide.
