I currently have a 220V pool pump running off an Intermatic T103 timer. I'm in the process of replacing the pump, and every pool website I go to says I should be using the T104 timer. Intermatic's website lists only the T104 as a swimming pool timer product.
Both the 103 and the 104 are DPST, but the T103 timer has a 110v clock and the T104 is a 220v clock. Other than that I can't see a difference (except that the T104 goes up to 277V, which is not relevant to me).
Is there any reason I should spend the money to switch to the T104?
