Dear customer,

Here is how to choose between the two based on your goals:

• Choose EPA mode if long-term water savings are your top priority:

  EPA mode allows the soil moisture level to deplete to a lower threshold before triggering the next cycle. It waters for a slightly longer duration when it does run, but spaces out the watering days the most, yielding the highest water conservation.

• Choose Deep mode if root depth is your main focus right now:

  Deep mode is specifically tuned to deliver thorough, deep soil penetration to encourage roots to anchor deeper into the subsoil, which is ideal during cooler months when surface evaporation is low.

Recommendation:

Start with Deep mode for the cooler season to establish strong, deep root systems. Once your lawn/plants are well-established, you can switch to EPA mode for maximum water savings heading into the warmer seasons.
