Seasonal Adjustment is used to make global run time changes without re-programming the entire controller. To use the Seasonal Adjustment feature:
NOTE: The controller should always be initially programmed in the 100% position.
Turn the dial to the SEASONAL ADJUSTMENT position.
The display will now show a flashing number followed by a %, as well as the bar graph on the left side of the display which always remains on the display. Press the plus (+) or minus (-) button to adjust the percentage of the seasonal adjustment. Each bar on the graph represents 10%. This feature can adjust the controller from 10% to 150% of the original program
To view the adjusted run times, simply turn the dial to the RUN TIMES position, the displayed run time will be updated accordingly as the seasonal adjustment is made. When using a Hunter “Clik” weather sensor, the Seasonal Adjustment value can be adjusted as described.
When using the Solar Sync ET sensor, the Seasonal Adjustment value is automatically updated daily based on the Solar Sync sensor. The Solar Sync ET sensor measures weather patterns, determines the optimal Seasonal Adjustment value, and then updates the controller on a daily basis. This value can be overridden manually by pressing the plus (+) or minus (-) buttons to the desired Seasonal Adjustment value. However, it is important to understand that the manually adjusted Seasonal Adjustment value will be replaced at midnight by the new updated value from the Solar Sync sensor.
To revert to a manually adjusted mode, the Solar Sync sensor must be uninstalled. See Uninstalling a Solar Sync Sensor.
