For controllers with the Solar Sync Module installed, the Region and Water Adjustment is made on the Solar Sync Module.
For accurate measurements, the Solar Sync module needs to be programmed for the typical ET (average July ET) for your region. Press the right arrow button until the arrow is displayed over the icon. Use the or button to select your region (regions 1 through 4).
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 until the arrow is displayed over the 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.
