Hunter Wireless Rain-Clik Sensor
OWNER'S MANUAL
Wireless Rain-Clik Features
To prevent water waste, built-in Quick Response® Technology instantly shuts down irrigation as soon as it starts raining.
Key Benefits
- Quick Response: Innovative technology that turns off the irrigation system immediately rather than after it has accumulated a fixed amount of rain. No calibration is required.
- Maintenance-Free Design: Provides trouble-free operation for at least 5 years. There are no batteries to replace.
- Wireless Operation Up to 800' (243 m): No wires are required between the rain sensor and controller.
- Water-Saving Sensor: Acts as a switch to deactivate automatic watering of your irrigation controller when it rains. Once rain has stopped and the sensor has dried out, automatic irrigation will resume. The sensor also halts irrigation when temperatures drop to 37°F (3°C) or below. The system will resume normal operation once temperatures increase.
- Automatic Synchronization: The Wireless Rain-Clik Transmitter will send wireless signals every hour to the receiver to ensure that the sensor and receiver are continuously synchronized.
- Lost Communication/Battery Status Indication: The Sensor Bypass LED will flash RED if the receiver has not received a signal from the transmitter. This can indicate a low or dead battery.
Wireless Rain-Clik Components
Wireless Rain-Clik Sensor
- 1. Manual Test Spindle: Press and hold the manual test spindle to confirm proper operation of your transmitter.
- 2. Vent Ring: Used to adjust the reset rate or dry out time for the sensors. Opening the vents will decrease the reset rate, while closing the vents will increase the time it takes for the discs to dry out.

Mounting the Sensor
Surface Mounting
Using the screws provided with your sensor, mount the transmitter on any surface where it will be exposed to unobstructed rainfall but not in the path of sprinkler spray. The sensor should be oriented upright (as pictured), but the swivel bracket can be moved for mounting on any angled surface. Loosen the locknut and screw before swiveling the bracket, and then retighten.
Illustration of surface mounting the sensor.
Gutter Mounting
The Sensor Gutter Mount (SGM) allows the transmitter to be mounted directly to the edge of a gutter. Install the SGM on the transmitter by removing the metal extension arm supplied with your sensor and reinstalling the SGM. Position the gutter mount on the edge of the gutter and twist the thumbscrew to secure it in place.

Adjustments and Operation
Tips for Mounting the Sensor
- Choose a location, such as the side of a building or post. The closer the transmitter is to the receiver, the better the reception. Do not exceed 800' (243 m).
- To ensure maximum range in communication, mount the receiver and transmitter away from sources of electrical interference (e.g., control panels, transformers, etc.) or metal objects. Best performance is obtained when no physical obstruction lies between the transmitter and receiver.
- Correct placement of the Wireless Rain-Clik model is important for accurate temperature sensing. The best location is out of direct sunlight.
- The reset rate refers to the amount of time it takes the sensor to dry out and resume its normal operation. The mounting location will affect this rate. For example, mounting the transmitter in a very sunny location may cause the sensor to dry out more quickly than desired. Similarly, mounting the sensor in constant shade may keep the sensor from drying out sooner.
Receiver Operation
The receiver has two LED lights that indicate the state of the system.
- SENSOR STATUS LED:
RED - Sensor is wet (watering disabled).
GREEN - Sensor is dry (watering enabled).
YELLOW – Sensor is in addressing mode. - SENSOR BYPASS LED:
RED – Rain sensor is bypassed (even though the sensor is bypassed, the STATUS LED will continue to alert you of the state of the sensor – wet or dry).
OFF - Rain sensor is enabled.
FLASHING RED – Indicates that communication between the transmitter and receiver was lost.

Note: When you first apply power to the receiver, the SENSOR STATUS LED will be RED. Press the manual test spindle on the transmitter for five seconds and release the spindle. The SENSOR STATUS LED will turn GREEN, indicating proper operation.
Bypassing the Sensor
The sensor can be bypassed by using the built-in bypass feature on the receiver. To bypass the sensor, press the SENSOR BYPASS button on the receiver. The bypass status light will turn red when the sensor is bypassed. Pressing the SENSOR BYPASS button again will re-enable the sensor, and the sensor bypass light will go out.
Setting the Transmitter Address at the Receiver
Each transmitter is produced with a unique address. A receiver must learn this address to work with that transmitter. This step is only necessary if transmitters and receivers are purchased separately.
- Prior to applying power (yellow wires) to the receiver, press and hold the bypass button on the receiver.
- While the bypass button is depressed, apply power to the receiver. The sensor status indicator light should light up yellow, indicating that the receiver is ready to learn a new address.
- Press and hold the quick response button on the transmitter.
- Within four seconds, the receiver's sensor status indicator light should turn red. The receiver has now learned the address, which will be retained even in the event of a power outage.
- Release the button on the transmitter. The sensor status indicator light should turn green.

Note: Units purchased as a kit will already have their communication address preset. No addressing is necessary. However, if the receiver or transmitter is replaced, you'll need to reset the address.
Adjustments and Operation
Battery Life
The Wireless Rain-Clik Transmitter is designed to operate for at least 5 years with its sealed, maintenance-free battery. The transmitter is available as a replacement part (WR-CLIK-TR). Should you need to change the transmitter, the receiver will have to learn the new transmitter address.
Checking the Status of the Battery in the Transmitter
- Press and hold the quick response spindle at the top of the sensor on the short stack.
- Within a few seconds, the LED light on the bottom of the sensor will briefly flash.
- Release the spindle, and the LED light will flash again. If the LED flashes, the battery in the transmitter is good.
