kind of like what i have for my pump right now...my pump was wired to a wall switch in my pool shed. i wanted to put in a timer before i get the autopilot SWG. so, i wired the power that went to the pump wall switch to the timer, the load out on the timer goes to the wall switch now to the pump so i have the option to turn off the pump without shutting the switch off in the timer. (convenient if i need to turn off the pump for a minute during timer cycle to clean the basket, switch my filter multiport valve from filter to backwash, etc). the SWG will be fed off the same "line in/load out" circuits as the pool pump. only thing i plan different for it then the pump is that the SWG will not be wired to the "2nd" on/off switch. i know it's not advised to rely completely on the flow valves on the SWG's to shut them off if the pump is off, but the rare time i'll use the wall switch to turn off the pump rather than the timer switch, i'm in the shed anyway and could turn off the timer switch so everything is killed , if i needed to.
