    Pool timer info needed

    I currently manage two pools. One at my house and one at a rental property. I would love to have a timer for the pump so I don't have to turn them on and off or leave them running every day. Both pools are equipped with a SWG. Typically I never mess with the switch on the SWG, I just let it shut off automatically when it detects no flow.

    Both pools have a similar setup. Both with a 1.4 HP Centurion pump (I don't know more than that off hand, but can look it up if no one knows the AMP rating). Both are wired for 220v. They are both wired directly from the pump to a breaker panel mounted on the exterior wall of the house. I turn them on and off by flipping the breaker, so I'm assuming I'm going to have to wire something inline unless there's something that can be installed in the breaker box to do this.

    I've been browsing a little, looking for something that will work, but I figured you all would have experience with timers that work well and ones that don't.

    Looking forward to suggestions on this as it will just make things a little easier.

    Thanks,

    The Intermatic T104 for about $50 is the "old reliable" of pool timers http://www.amazon.com/Intermatic-T104-2 ... B000BQOX88

    Re: Pool timer info needed

    Is there a preference to that timer vs. this one?

    Re: Pool timer info needed

    Along these same lines, my setup lends asking another question.

    I have a booster pump, which is also wired the same way my pool pump is, straight to the breaker box. Since they are wired seperately, there's a chance that I could get forgetful at some point and leave the booster pump on, across the shut off threshhold of the pump run time and that would leave the booster pump running while there was no water circulating. I'm not 100% sure, but I'm assuming this is a not a good idea. Would I be able to wire in a relay on the load side of the timer that would open when the timer trips to prevent the booster pump from staying on when there was no power to the pump (via the timer). I believe this will work, just making sure the timer can handle that bit of extra amp draw.

    You can use a current sensing relay, as described in this post to make sure the booster pump doesn't come on at the wrong time.

    Running the booster when the main pump is off is indeed a bad thing. For a little while probably wouldn't do anything, but the more it runs that way the more likely it is to damage the booster pump.

    Re: Pool timer info needed

    I installed the timer prior to opening the pool this season. Install went pretty well and now I'm just waiting to complete the opening process before starting to dial in the timer. I'm looking forward to not having to remember to turn the pump on/off every day.

    Re: Pool timer info needed

    The power to the SWG should come from the load side of the timer. You should not just be relying on the flow switch to prevent the SWG running while the pump is off ... could result in a buildup of explosive gas.

    I did not wire in this fashion but I can change it fairly easily. What sort of explosive gas would be generated by the SWG running? Sorry but I'm not that familiar with this. FYI, I've been using the pump, albeit manually, in this fashion for 2 years per the instruction of the installer. (I know that it only takes once...)

    Re: Pool timer info needed

    I'm assuming wiring in a relay to remedy this would be the better solution rather than trying to cram all of these wires into the timer box.

    Hydrogen gas. As long as the flow switch works, you are fine. In the manual it specifically states to not rely on just the flow switch.

    The relay will work as well.

    Re: Pool timer info needed

    After doing some reading on the loads of the pump and SWG, it looks like the timer will handle the load of both just fine, no need for a relay. I'll take care of that soon. Probably add the booster pump as well just to be safe.

    Re: Pool timer info needed

    Got to thinking some more on this and I'm going to have to go back to the relay plan. Can't have one breaker pushing the load for all of this equipment...

    Re: Pool timer info needed

    The breaker should be fine running the filter pump and SWG, but agree that booster should likely be on a separate circuit.

    240 vs 120, won't work.

    Re: Pool timer info needed

    AquaRite can be wired for either 120 or 240.
