Choosing the right pool timer?

[GhostyGhost]

Hi All,

I had my old pool timer die on me last year and was going to wire in the new one this year so I don't need to manually control the pump anymore. The old timer was a digital Paragon Electric EC4004PC/208-240. I took a look at my pump and breaker and the pump is set at 115v and the breaker is a single 20A switch. Would there be any harm in downsizing the timer to something like the intermatic t101? In case it helps confirm anything I've attached a picture of my current manual wiring along with how it used to be wired and the current pump setting.

I bought a t104 already thinking I was going to need something rated for 240v but now I'm thinking it is worth downsizing.

Thanks!

A T104 timer will not work in your box since the T104 has a 240V motor and you have 120V into your electrical box.

You need a T101 timer that has a 120V motor.

Thanks for that link and confirming my suspicions! wonder why the previous owner had the 240v timer wired up...

If you have the 240V timer look at the back at what voltage is stamped on the motor.

There is a T103 with a 120V motor and 240V contacrs.
