CONNECTING A HUNTER SOLAR SYNC
This controller is compatible with the Solar Sync and Wireless
Solar Sync systems. Solar Sync is a sensor system that will
automatically adjust the 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 evapotranspiration (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 first full day (24-hour period)
of weather measurements have been received from
the sensor.
NOTE: Enabling the Sensor Bypass switch has no
effect on the seasonal adjust updates from the
Solar Sync sensor. 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
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
left and the default Water Adjustment setting (5) on the right.

Sync Settings position. The number
