It’s a good year to install this product!

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 Sync’s seasonal adjustment value to modify the actual irrigation run time 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.

The Wireless Solar Sync System is simply and easily installed on any compatible Hunter Irrigation controller (see Owner’s Manual to verify

compatibility). The Wireless Solar Sync Sensor measures solar radiation and temperature and calculates the daily evapotranspiration (ET)
factor for irrigation. This represents the amount of water lost by the plants due to local climate conditions, which needs to be replaced by
irrigation. The Wireless Solar Sync also includes Hunter Rain-Clik™ and Freeze-Clik ®sensors that will automatically shut down the irrigation
system during rain events or freezing conditions.
Enter a mid summer watering program in your controller per the programming instructions in the Owner’s Manual provided with your
controller. The Wireless Solar Sync Sensor sends weather data and applies it daily to the controller’s water schedule by adjusting the
controller through the seasonal adjust feature.
This Owner’s Manual applies to the following kits:
WSS: Wireless Solar Sync kit for Hunter Pro-C, PCC, ICC, and I-Core controllers
WSSSEN*: Wireless Solar Sync kit for Hunter ACC and X-Core controllers
*Note that WSSSEN does not include the Solar Sync Module. The ACC and X-Core controllers have the Solar Sync software built in and do
not require the Solar Sync Module. Therefore, the WSSSEN should be used with the ACC and X-Core Controllers.
