Wireless Rain-Clik FeaturesTo prevent water waste, built-in Quick Response Technology instantly shuts down irrigation as soonas it starts raining.Key Benefits1. Quick Response: Innovative technology that turnsoff the irrigation system immediately rather thanafter it has accumulated a fixed amount of rain. Nocalibration is required.6. Automatic Synchronization: The Wireless Rain-Cliktransmitter will send wireless signals every hour tothe receiver to ensure that the sensor and receiver arecontinuously synchronized.7. Lost Communication/Battery Status Indication: TheSensor Bypass LED will flash RED if the receiver has notreceived a signal from the transmitter. This can indicatea low or dead battery.2. Maintenance-Free Design: Provides trouble-freeoperation for at least 5 years. There are no batteriesto replace.3. Wireless Operation Up to 800' (243 m): No wiresare required between the rain sensor and controller.4. Wireless Rain-Clik Sensor (WR-CLIK): Acts as a switchto deactivate automatic watering of your irrigationcontroller when it rains. Once rain has stopped and thesensor has dried out, automatic irrigation will resume.5. Wireless Rain/Freeze-Clik Sensor (WRF-CLIK):The Wireless Rain/Freeze-Clik includes a freezesensor that is designed to keep the irrigationsystem from operating when temperatures drop to37 F (3 C) or below. When temperatures rise abovethis temperature, the sensor will enable automaticwatering.3

Wireless Rain-Clik ComponentsWireless Rain-Clik Sensor②1. Manual Test Spindle: Press and hold the manual testspindle to confirm proper operation of your transmitter.➊2. Vent Ring: Used to adjust the reset rate or dry out timefor the sensors. Opening the vents will decrease thereset rate, while closing the vents will increase the timeit takes for the discs to dry out.3. Radio Antenna: Transmits a wireless signal to thereceiver up to 800' (243 m). The antenna should beoriented vertically.4. Mounting Arm: Metal extension arm for mountingthe sensor.5. Battery Status LED: Used to determine the status ofthe sealed battery. Pushing the manual test spindle willflash the LED light indicating that the battery is good.➍③⑤4

Mounting the SensorSurface MountingGutter MountingUsing the screws provided with your sensor, mount thetransmitter on any surface where it will be exposed tounobstructed rainfall, but not in the path of sprinklerspray. The sensor should be oriented upright (as pictured),but the swivel bracket can be moved for mounting onany angled surface. Loosen the locknut and screw beforeswiveling the bracket, and then re-tighten.The SGM allows the transmitter to be mounteddirectly to the edge of a gutter. Install the SGM onthe transmitter by removing the metal extension armsupplied with your sensor and reinstalling the SGM.Position the gutter mount on the edge of the gutter andtwist the thumbscrew to secure it in place.SGMSurface Mount8Gutter Mount

Adjustments and OperationTips for Mounting the SensorReceiver Operation Choose a location such as the side of a building or post.The closer the transmitter is to the receiver, the betterthe reception. Do not exceed 800' (243 m).The receiver has two LED lights thatindicate the state of the system. To ensure maximum range in communication, mountthe receiver and transmitter away from sourcesof electrical interference (e.g., control panels,transformers, etc.) or metal objects. Best performanceis obtained when no physical obstruction is betweenthe transmitter and receiver. Correct placement of the Wireless Rain/Freeze-Clikmodel is important for accurate temperature sensing.The best location would be out of direct sunlight. The reset rate refers to the amount of time it takesfor the sensor to dry out sufficiently for the sprinklersystem to be allowed to come back on. The mountinglocation will affect this rate. For example, mountingthe transmitter in a very sunny location may causethe sensor to dry out sooner than desired. Similarly,mounting the sensor in constant shade may keep thesensor from drying out sooner.1. SENSOR STATUS LED:RED – Sensor is wet(watering disabled).GREEN – Sensor is dry(watering enabled).YELLOW – Sensor is inaddressing mode.CLIK RECEIVER2. SENSOR BYPASS LED:RED – Rain sensor is bypassed (even though the sensoris bypassed, the STATUS LED will continue to alert youof the state of the sensor — wet or dry).OFF – Rain sensor is enabled.FLASHING RED – Indicates that communicationbetween the transmitter and receiver was lost.NoteWhen you first apply power to the receiver, theSENSOR STATUS LED will be RED. Press themanual test spindle on the transmitter for fiveseconds and release the spindle. The SENSORSTATUS LED will turn GREEN indicatingproper operation.9

Adjustments and OperationBypassing the SensorThe sensor can be bypassed by using the built-in bypassfeature on the receiver. To bypass the sensor, press theSENSOR BYPASS button on the receiver. The bypassstatus light will turn red when the sensor is bypassed.Pressing the SENSOR BYPASS button again will re-enablethe sensor and the sensor bypass light will go out.Setting the Transmitter Address at the ReceiverEach transmitter is produced with a unique address.A receiver must learn this address to work with thattransmitter. This step is only necessary if transmitters andreceivers are purchased separately.1. Prior to applying power (yellow wires) to the receiver,press and hold the bypass button on the receiver.2. While the bypass button is depressed, apply power tothe receiver. The sensor status indicator light shouldlight up yellow indicating that the receiver is ready tolearn a new address.3. Press and hold the quick response button on thetransmitter.4. Within four seconds, the receiver’s sensor statusindicator light should turn red. The receiver has nowlearned the address and it will be retained even in theevent of a power outage.5. Release the button on the transmitter. The sensorstatus indicator light should turn green.NoteUnits purchased as a kit will already have theircommunication address preset. No addressing isnecessary. However, if the receiver or transmitteris replaced you need to reset the address.LED Light10

Adjustments and OperationBattery LifeThe Wireless Rain-Clik Transmitter is designed to operatefor at least 5 years with its sealed, maintenance-freebattery. The transmitter is available as a replacementpart (WR-CLIK-TR). Should you need to change thetransmitter, the receiver will have to learn the newtransmitter address.If you are experiencing problems with your WirelessRain-Clik Sensor, follow these simple checks first beforeassuming the unit is defective and replacing it.System Will Not Turn On at All Check to make sure that the sensor discs are dry andthe switch “clicks” on and off freely by pressing the topof the spindle.To Check the Status of the Battery in theTransmitter Look for breaks in the wire leading to the receiver andcheck all connections.1. Press and hold the quick response spindle at the topof the sensor on the short stack. Verify outside air temperature (for Rain/Freeze-Clikinstallations).2. Within a few seconds the LED light on the bottomof the sensor will briefly flash.System Will Not Shut Off Even After Heavy Rainfall3. Release the spindle and the LED light will flash again. Ifthe LED flashes, the battery in the transmitter is good. Remove the sensor jumper across the two SENterminals. Check to make sure that rainfall is hitting the sensor. Look for breaks in the wire leading to the receiverand check all connections.SCANfor help Check the battery in the transmitter.Sensor Bypass LED Is Flashing Red Make sure the battery in the transmitter is good.https://hunter.help/wrclik Check for obstructions around the transmitter orreceiver antenna.11
