The Hunter Solar Sync Owner’s Manual provides installation, programming, calibration, and troubleshooting instructions for the Solar Sync sensor and module.
The Solar Sync system is a sensor‑module package that connects to a compatible Hunter irrigation controller. The sensor measures solar radiation, temperature, and evapotranspiration, and includes Rain‑Clik™ and Freeze‑Clik™ sensors to automatically shut down watering during rain or freezing conditions. The module receives data from the sensor and adjusts the controller’s watering schedule accordingly.
The manual covers system overview, step‑by‑step installation of the sensor and module, wiring diagrams for various controller families, programming procedures, calibration settings, and troubleshooting tips. It also lists technical specifications, FCC notice, and European conformity certification.

The module uses a CR2032 lithium backup battery with an expected life of ten years.
The sensor can be installed up to 200 ft (60 m) away from the module.
Rain‑Clik uses patented Quick Response™ technology to shut the system off during the first few minutes of rainfall.
Move the bypass switch on the controller to the BYPASS position; the Rain and Freeze sensors will then be bypassed.
