The flow control knob works very similar to a hose bib or gate valve as its main function is to either fully allow or restrict the amount of water passing through the valve.

In most installations, the Wind-Clik acts as a switch to break the circuit to the solenoid valves of the irrigation system during high wind conditions. This allows the timer to advance as scheduled, but keeps the valves from opening the water flow. Once the wind conditions drop below the reset point, the switch closes again to allow for normal operation. This is performed by the wind action of the vanes. They rotate about 180°, and DO NOT SPIN.

The correct placement of the Freeze-Clik is critical for accurate temperature sensing. It must be mounted out of direct sunlight, and where free outdoor air circulation is possible. Examples would be the north wall of a building or under eaves and overhangs.

Before wiring your Rain-Clik, it is important to select an appropriate mounting location for the transmitter. Click here to view mounting instructions for the Rain-Click transmitter.

Once the Rain-Clik is mounted, run the wire to the controller, and fasten it every few feet with wire clips or staples for best results. If an extension to the wire provided is needed, use the following table to determine the minimum wire gauge needed:

The Rain-Clik, Wireless Rain-Clik, and Solar Sync provide instant shut off, thanks to Hunter’s Quick Response feature.

The Hunter Mini-Clik, Rain-Clik and Wireless Rain-Clik are compatible with all brands of irrigation controllers and can be installed by your professional irrigation contractor. Rain sensors are required by law in some areas, so it is a good idea to check with your contractor or local water authority before having an irrigation system installed.

You can manually test proper operation of the rain sensor by using the One Touch Manual Start. During the Manual All stations cycle, press the test button on the “Clik-type” sensor (eg. Mini-Clik®) to interrupt watering.

Note: The rain sensor will only interrupt watering in Manual All Stations and automatic programming.  Manual single station will override the sensor circuit.

The dry out time could be as little as 4 hours depending on the weather conditions (temperature and humidity) and the rain threshold that is set. If the weather conditions remain cold and damp, your sensor could be active for months.

Hunter Rain Sensors and Solar Syncs have two seperate options for setting a rain shutdown threshold:

There are two reasons why a sprinkler will leak water when the system is supposed to be off.

  • The most common reason is called “Low Head Drainage”. "Low Head Drainage" occurs when the lowest head on a zone allows water to drain from the lateral piping, out of the sprinkler. If it is low head drainage, residual water will stop flowing after all the water has left the pipe.

The solution is to install check valves, such as the HCV, on sprinklers and lateral lines.
