The Solar Sync is simple to program. Only a few initial steps are necessary to program the module. When power is initially turned on, the display will show the time of day. Pressing the button will sequence through the programming functions on the module. An arrow along the bottom of the display will indicate the function being programmed.
If using the Solar Sync with the ACC or X-Core Controllers, consult the controller owner’s manual for programming details. (ACC and X-Core controllers do not use the Solar Sync module.)
Press the button press until the arrow is displayed over the icon. The time of day will be flashing. Use the or button to set the current time. The arrow to the right of the display indicates AM or PM.
Note: 24 hour mode will only be enabled with a 50 Hz power input.
Press the button until the arrow is displayed over the ICON icon. Use the or button to select the correct Hunter controller.
Region: For accurate measurements, the Solar Sync module needs to be programmed for the typical ET (average July ET) for your region. Use the table on the next page to determine your region. Press the button until the arrow is displayed over the ICON icon. Use the or button to select your region. (Region 1 through 4)
The table will assist you in identifying the type of region you live in. There are four basic ET regions, each with descriptions of the region, along with typical ET and temperature characteristics. It is recommended that, if possible, the region be chosen based upon average July ET or peak summer ET (inches/mm per day).
Use the following table for choosing your region (reference below). You can use A, b or C to help you choose which region is best for your area:
A: Based upon the ET of your region using the average July ET or peak summer ET (inches/mm per day). This is the preferred option when selecting your region
b: Based upon the temperature for your region using the average July or the driest month high temperature (not the highest temperature for July)
C: Based upon the general description of your region
If you find that your landscape is “wetter” or “drier” than it should be, a watering adjustment function is provided to adjust watering equally to all stations. Use the button on the module until the arrow is displayed over the ICON icon.
Use the or button to increase or decrease the amount of watering scaled 1 to 10 (1 for less water and 10 for more water). Hunter recommends observing performance carefully over the first weeks of operation before adjusting the watering.
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.
If required, the Solar Sync offers a no water window capability that prevents any irrigation from occurring during a specific period of the day. The No Water Window is a hidden feature. Press and hold the button on the module for 5 seconds to program the No Water Window.
An will be flashing at Start along the right side of the display. Use the or button to adjust the time you would like the no watering period to start. Pressing the button again will display an arrow flashing at End. Use the or button to adjust the time you would like the no watering period to end.
