CONNECTING A HUNTER SOLAR SYNC ET SENSOR
The X-Core is compatible with the Solar Sync and Wireless Solar
Sync systems. Solar Sync is a sensor system that will automatically
adjust the X-Core controller’s watering schedule (based on changes
in local climate condition) by using the Seasonal Adjust function. The
Solar Sync uses a solar and temperature sensor to determine evapo-
transpiration (ET), or the rate at which plants and turf use water, and
also includes Hunter Rain Clik and Freeze Clik technology that will
shut down irrigation when it rains and/or during freezing conditions.
NOTE: Solar Sync will apply a default seasonal adjust
value of 100% until the rst full day (24 - hour period)
of weather measurements have been received from the
sensor.
NOTE: Enabling the Sensor Bypass switch has no eect
on the seasonal adjust updates from the Solar Sync sen-
sor. It will, however, bypass the Rain Clik and Freeze Clik
functionality of the sensor.
Installing Solar Sync Sensor
Connect the Green and Black wire from the Solar Sync Sensor to the
“SEN” wiring terminals on the X-Core controller, similar to picture
on page 11. It does not matter which
wire connects to which terminal. Turn
the dial to the “Solar Sync Settings”
position. The display will initially show
dashed lines and then will show the
default Region setting (3) on the le
and the default Water Adjustment setting (5) on the right. Adjust
the Region as needed by using the
and buttons (refer to page
13 for explanation of Solar Sync Region setting). Use the button
to advance to the right to adjust the Water Adjust setting as needed
(see page 14 for explanation of Water Adjust setting).
Installing the Wireless Solar Sync
Connect the Green and Black wire from the Wireless Solar Sync
Receiver to the “SEN” wiring terminals on the X-Core controller. It
does not matter which wire connects to which terminal. Turn the dial
to the “Solar Sync Settings” position. The display will initially show
dashed lines and then will show the default Region setting (3) on
the le and the default Water Adjustment setting (5) on the right.
Adjust the region as needed by using
the and buttons (refer to page
13 for explanation of Solar Sync Region
setting). Use the button to advance
to the right to adjust the Water Adjust
setting as needed (see page 14 for
explanation of Water Adjust setting).
Solar Sync Settings
Once the Solar Sync sensor is connected to the X-Core controller,
two numbers will appear in the display when the dial is turned to the
Solar Sync Settings position. The number on the le of the screen is
the Region setting, and the number on the right on the screen is the
Water Adjustment setting (as shown above).
NOTE: The Solar Sync module is not required for
installation using the X-core Controller.
