After Solar Sync has been installed and programmed, we recommend allowing the system to run for a few days at the initial setting. Because of the variety in site conditions (including sensor location, amount of direct sunlight available to the sensor, reflective heat from surrounding structures, etc.), the initial setting may require adjustment in order to achieve the desired performance. The calibration of the Solar Sync to a particular site can easily be accomplished by adjusting the Region and/or Water Adjustment settings.
The instructions below outline this process:
Make sure the controller dial is in the RUN position. 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 Adjustment %. 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).
Make sure the controller dial is in the RUN position. 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).
The table below will assist you in identifying the region in which you live. There are four basic ET regions, each with descriptions of the region and typical ET and temperature characteristics. If possible, we recommend choosing the region based upon average July ET or peak summer ET.
