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:
* For Southern hemisphere locations, use the month of January.
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.
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 stays 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, increase or decrease the amount of run time on the controller.
