Hunter WSS-SEN - Wireless Solar Sync Rain/Freeze Sensor, Receiver, & Gutter Mount

The Solar Sync ET sensor is an advanced weather sensor that calculates evapotranspiration (ET) and adjusts Hunter controllers daily based on local weather conditions. 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 Syncs seasonal adjustment value to modify the actual irrigation run time for that day. In addition, the Solar Sync ET sensor integrates Hunters 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.
