Solar Sync measures sunlight and temperature and uses ET to determine the correct seasonal adjustment percentage value to send to the controller. The controller then uses its programmed run time and adjusts to Solar Sync’s seasonal adjustment value to modify the actual irrigation runtime for that day. In addition, the Solar Sync ET sensor integrates Hunter’s popular Rain-Clik™ and Freeze-Clik® sensors providing quick response in shutting down your irrigation system during rain and/or freezing conditions. The Solar Sync is compatible with most Hunter controllers and applicable to residences, businesses, and municipalities alike.
