If the Solar Sync Seasonal Adjustment is too high or too low you may need to change the Water Adjustment feature on your controller or Solar Sync Module on older models. This will allow you to fine-tune your station Run Times to allow for more watering or less watering.
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 instructions below are for changing these settings on controllers with the Solar Sync on the dial position and older units that use the Solar Sync module (e.g; PC-300, ICC, etc.).
Seasonal Adjust too low: Increase the value on the Water Adjustment scale (10 is max). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust %. Increase the Water Adjustment setting until the desired Seasonal Adjust % is shown. If you max out the Water Adjustment scale at 10 and still require more Seasonal Adjust, move down to the next lower Region (from Region 4 to 3, for example).
Seasonal Adjust too high: Decrease the value on the Water Adjustment scale (default setting is 5). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjust %. Decrease the Water Adjustment setting until the desired Seasonal Adjust % is shown. If you minimize the Water Adjustment scale down to 1 and still require a reduction in Seasonal Adjust, move up the next Region (from Region 2 to 3, for example).
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.

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.:
REGION 1
REGION 2
REGION 3
REGION 4
* For Southern hemisphere locations, use the month of January.
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.
