This weather station mounted on your property will continually monitor the ambient air temperature, which in turn, helps the controller compute the EPT (EvaPoTrans-piration) for the day. What is EPT? It is a scientific formula the computes how fast the soil loses moisture through evaporation.

The last 25 years, irrigation technology has been targeting water consumption.
With these new technologies, we can save homeowners money, and help the environment too!

Using a tipping rain gauge, the controller accurately assesses not only the total amount of rainfall, but how fast the rain falls (which affects how much water is absorbed by the soil before runoff occurs). This helps especially with properties that have sloping landscapes.

Factor Irrigation will program your new ESP Smart Clock controller with the unique data about each coverage zone in your lawn. Because each area of your lawn is different, the data listed to the right are programmed into the controller, and the Smart Clock controller does all the work from there. It decides how much to water each zone, and when, saving thousands of gallons of water yearly.

We will program specific data about each zone, such as:
• Soil type
• The slope
• Sun/shade
• Plant type
• Precipitation rate
• Zip code (provides last 20 years of weather history to the controller)
