HUNTER WIRELESS SOLAR SYNC SENSOR (MODULE NOT INCLUDED) FOR X-CORE AND ACC CONTROLLERS:

Wireless Sensor/Receiver only kit for controllers with Solar Sync software built in. X-Core and ACC controllers have the Solar Sync software built in and do not require the module. So, if you have an X-Core or ACC controller and want the SOLAR-SYNC, all you have to buy is the SOLARSYNSEN (Wired Version) or the WSSSEN (Wireless Version).

Air temperature is monitored and used to calculate watering requirements. Too hot? Solar Sync knows to be efficient and waters your lawn as needed. Freezing morning? Keep those mittens off, because below 37° F, Solar Sync smartly waits for warmer temperatures.

Passing showers require a sensor that can react quickly.
The built-in "Quick Response™" feature does just that.

For soaking showers, the adjustable Rain-Clik™ sensor
ensures your lawn isn't watered unnecessarily.

Let the sun shine in. The solar sensor measures the sun's rays to keep your lawn at peak performance with optimal watering.
