X-Core - Setting Solar Sync Region and Water Adjustment

Topics: 
FAQs, Troubleshooting
Region Settting

For accurate Solar Sync measurements, the controller needs to be programmed for the average peak season ET for your region.

Use the following table for choosing your region. You can use methods A, B or C to help you choose which region is best for your area:

  • A - Based upon the ET of your region using the average July ET or peak summer ET (inches/mm per day). This is the preferred option when selecting your region.
  • B - Based upon the temperature for your region using the average July or the driest month high temperature (not the highest temperature for July).
  • C - Based upon the general description of your region.

REGION 1

  • A - If the average July ET is < 0.17" (4.3 mm) per day
  • B - If the average temperature for July is 65°–75° (18°C – 24°C)
  • C - U.S. Northern States / Coastal Regions

REGION 2

  • A - If the average July ET is 0.18" – 0.23" (4.6 mm ­– 5.8 mm) per day
  • B - If the average temperature for July is 75° – 85° (24°C – 29°C)
  • C - Mountains / U.S. Northern Inland States

REGION 3

  • A - If the average July ET is 0.24" – 0.29" (6.1 mm – 7.4 mm) per day
  • B - If the average temperature for July is 85° – 95° (29°C – 35°C)
  • C - U.S. Southern States / Inland/High Desert

REGION 4

  • A - If the average July ET is > 0.30" (7.6 mm) per day
  • B - If the average temperature for July is 95° – 105° (35°C – 41°C)
  • C - Deserts

* For Southern hemisphere locations, use the month of January.

 

Changing the Region Setting

Turn the dial to the “Solar Sync Settings” position. The display will show the Region setting on the left and the Water Adjustment setting on the right. The Region number will be flashing. Adjust the region as needed by using the and buttons.

NOTE: If an individual zone is “wetter” or “drier” than the rest of the system, simply increase or decrease the amount of run time on the controller.

 

Water Adjustment

Water Adjustment Setting

The Water Adjustment is a 1 to 10 scale that allows for easy adjustment of the Seasonal Adjust value from the Solar Sync ET Sensor. Upon installation of the Solar Sync ET Sensor, it is recommended that the Water Adjustment setting stay at the default value of 5. However, after installation, if you find that the seasonal adjust value is lower or higher than expected, the Water Adjustment value can be modified to modify the Seasonal Adjust output value.

NOTE: If an individual zone is “wetter” or “drier” than the rest of the system, simply increase or decrease the amount of run time on the controller.

Changing the Water Adjustment

Turn the dial to the “Solar Sync Settings” position. The display will show the default Region setting on the left and the Water Adjustment setting on the right. The Region number will be flashing. Use the button to advance to the right to adjust the Water Adjust setting. Adjust the water adjsutment number as needed by using the and buttons.
