    Confused on timers.

    I've decided to install a timer so that I can run the pump less automatically. Originally I was going to just buy the plug in type, but found out that they are NOT designed for a 1.5hp pump motor.

    So I'm looking at hardwired timers. I bought one at Lowe's tonight on a quick stop and when I got home started reading about it. http://www.nsiindustries.com/Repository ... cSheet.pdf If I read this right, it won't work on my 1.5hp motor either.

    Am I reading the specs correctly? What kind of timers do you all use on 1.5hp pumps?

    Re: Confused on timers.

    I think you will find the intermatic brand timers to be widely regarded as the best option out there, the specific model you need may depend on how you plan to install, etc.

    Re: Confused on timers.

    I use the T101R. The "R" suffix indicates the timer is housed in a weatherproof box. For me, it was cheaper to get that model vs a standard 101 and a weatherproof box to house it in.

    If you opt for an Intermatic timer and are planning on running multiple on/off cycles, buy some extra trippers as the unit itself only comes with one pair.....which I'll add is a total cheap out on Intermatics part. The timer itself is great and simple to setup/use.

    Re: Confused on timers.

    The timer will be installed inside the house near the breaker box. So inside/outside doesn't matter to us.

    Do any of you have a 1.5hp pump motor? That seems to be my difficulty.

    Re: Confused on timers.

    While the Intermatic timers are the workhorses of the industry, in reality you only have a 1 hp motor or less. It's most likely a 1.5 spl rated pump. A lot of plug in timers will handle that. Just giving you options.

    Re: Confused on timers.

    The 101 is rated for 40A. Even at startup I doubt there will be an issue.

    I was gonna put my timer next to my panel but I'm also using it as my code required shutoff. The main issue I had with placing it in the basement was if the timer was OFF and I wanted to vacuum, it would require trips back and forth to the panel. I'm lazy. Something to think about if you are too.

    Re: Confused on timers.

    IIRC, when you place the timer in the basement, you will need a shutoff for the power within sight of the pool. NEC code, if i understand correctly.

    Re: Confused on timers.

    The specs on the timer you have says that it is good for up to a 2HP motor if it is wired for 240V. If yours is wired for 240V, you should be fine. Also the timer enclosure is a Nema 3R rating, so it is fine to be installed indoors or outdoors.

    We had an electrician do the electric work when it was first hooked up. It has out side GFI breakers installed on the side of the house going to the pool and convenience outlets. The timer will go in between the breaker box and outside GFI breaker box. He did it all to code including the copper bonding wire all the way around the pool which he really felt was a waste but had to be there to meet code. So everything he installed meets code.

    My pump has this information on it.

    RPM 3450

    SF Amps 12.0

    The reason I was looking at the TORK timer is that it had a battery backup and digital timer that can be set up to seven different on off settings. I had originally been looking at a TORK that was not digital but had the little pins that go all around for almost unlimited timer settings. Lowes was out of that one when I got there and had only the I mentioned above instead. Not sure I cared about the digital part, but really liked the battery backup part of it. It won't be exposed to the elements being inside.

    Just want to get something installed because it is well over $100 a month right now to run the pump 24/7.

    The electrician's bill says he installed a 20 amp 125 Volt twist lock outlet. Doesn't say what size wire used.
