Hi, I have an above ground pump with this twist lock plug, the pump has a 1/2 hp or 2 hp option. I only ever use the 1/2 hp, option and run the pump 24 hours. I’m looking to run the pump less and want this timer, however, will the 2hp setting bother the timer if I don’t run the pump on that setting? Thanks for your input!

A  Answered on 4/30/2019 by InyoPools Product Specialist Lennox H.

Hi, Robin. This timer will not be able to power the high-speed function of the motor. You can use this timer to operate the pump on the low speed. function. The pump must have a toggle with and operate at 115 volts in order to use this timer.

Clock is keeping time but not turning on pump or turning off.trippers are in the time that I set and there is power. Just started malfunctioning a week or two ago. The timer is approximately three years old. Any ideas. Thanks.

A  Answered on 8/27/2015 by InyoPools Product Specialist Bob D.

Hi Bob. I had the same problem with a similar model timer. I fixed it by replacing the small motor inside, which was pretty simple. If you power down and take a look at the inside you may find a part number for that motor. Otherwise you can give Intermatic a call at 815-675-7000 and check for a better solution.

Can this timer be mounted to a wooden receptacle post?

A  Answered on 12/11/2006 by InyoPools Product Specialist Patrick P.

According to Intermatic, the P1131has a keyhole on the back which will allow it to be mounted to a post with a screw or nail.  They recommend mounting the timer at least 1 foot above any standing water or snow.

Is the the plug or the receptacle twist lock?

A  Answered on 7/13/2006 by InyoPools Product Specialist Patrick P.

The recptacle on the timer is designed to accept a twist lock plug and the plug coming off of the timer is also twist lock. So both the receptacle and plug are twist lock.

I have a 1 1/2 HP Hayward filter, I need a timer box that I can connect to it. Will this handle it or do you have another timer that might?

A  Answered on 6/18/2006 by InyoPools Product Specialist Patrick P.

This will only accommodate up to 1.0 HP pump. If this is for an above ground pool pump then you could use the following timer SP1500FT http://www.inyopools.com/Products/02200022032590.htm

?     Asked on 6/5/2006by Guest

I have a twist lock plug on my filter. I am assuming that you can plug in this type of plug into the timer? Also my filter is a 1.5 HP and the specs say it is good for 1 HP. Can I use this or is there another model that will work?

A  Answered on 6/5/2006 by InyoPools Product Specialist Patrick P.

This timer is designed specifically for pumps with a twist cord, however it can only handle pumps up to 1.0 HP. We do not have a timer available for twist lock pumps over 1.0 HP.

Could not find a timer for a twist lock plug.

I wanted to add a timer to my pool pump, I ordered the hard wire one and then found this one on your web site. It is working excellent and was so easy to hook up. Its as easy as mount with two screws and plug it into the outlet and then plug the pump into the timer and then set the timer. Works great!! And you can turn you pump on and off from the timer.

Were these instructions helpful?
