In this video, learn how to properly install a Solar Sync sensor and learn the different Solar Sync programming functions, plus how to make future adjustments.
After Solar Sync has been installed and programmed, it is recommended to allow the system to run for a few days at the initial setting.
Because of the variety in site conditions (including sensor location, amount of direct sunlight available to the sensor, reflective heat from surrounding structures, etc), the initial setting may require adjustment in order to arrive at the desired performance. The calibration of the Solar Sync to a particular site can easily be accomplished by adjusting the Region and/or Water Adjustment settings. The instructions below outline this process:
Station Run Times: It is important to understand that Solar Sync provides a global seasonal adjustment to the controller. This means that all station run times will be modified by the seasonal adjust percentage shown. When programming the controller, the run times should be entered that represent peak season watering schedules. If the Solar Sync is adjusting to the appropriate seasonal adjust value but the run time for a particular station appears to be too long/short, adjust the station run time in the controller program.
NOTE: On the older model Pro-C controllers (green buttons) 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 button until the arrow is displayed over the globe 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 water 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.
