Water Adjustment
-
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, keep the
Water Adjustment setting 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 the Seasonal Adjust output value. See Calibration/Setup on page
15 for explanation of how to use Water Adjustment scale to fine-tune
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.

Uninstalling a Solar Sync Sensor
If a Solar Sync sensor has been installed, then the seasonal adjust
value used by the controller will be calculated from the weather
data supplied by the Solar Sync sensor.If the Solar Sync sensor is no
longer used with the controller, it must be uninstalled. If the Solar
Sync sensor is not uninstalled, the controller will not allow the
seasonal adjust value to be manually changed. For example, if the
seasonal adjust value shown on the controller was 50 percent when
the Solar Sync sensor was removed, it will remain 50 percent until
the Solar Sync sensor is uninstalled.
To uninstall the Solar Sync sensor, simply disconnect the green and
black wires from the controller terminal and then turn the dial to
the "Solar Sync Settings" position. The display should show dashes,
indicating that the controller no longer recognizes the Solar Sync
sensor for calculation of seasonal adjustment. Now the seasonal
adjust value can be changed manually by turning the knob to the
"Seasonal Adjust" position and using the + or - button to adjust
the value.
