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, 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.
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 on the X-Core controller
then the seasonal adjust value used by the controller will be
calculated from the weather data supplied by the Solar Sync sensor.
If it is decided that the Solar Sync sensor will no longer be used
with the X-Core 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% when the
Solar Sync sensor was removed, it will remain 50% 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.
