FeaturesWireless Rain-Clik features include:6. Automatic Synchronization – The Wireless Rain-Cliktransmitter will send wireless signals every hour tothe receiver to ensure that the sensor and receiver arecontinuously synchronized.1. Quick Response – Unique technology that turns offthe irrigation system immediately rather than after ithas accumulated a fixed amount of rain. No calibrationis required.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.Wireless Rain-Clik sensors attach quickly and easily toyour controller.2. Maintenance-Free Design – Provides trouble-freeoperation for up to 10 years. There are no batteries toreplace.3. Wireless Operation Up to 800' (275 m) – No wires arerequired between the rain sensor and controller.4. Two models available: Wireless Rain-Clik (WR-CLIK)– Acts as a switch to deactivate automatic wateringof your irrigation controller when it rains. Once rainhas stopped and the sensor has dried out, automaticirrigation will resume.5. Wireless Rain/Freeze-Clik (WRF-CLIK) – The WirelessRain/Freeze-Clik includes a freeze sensor that isdesigned to keep the irrigation system from operatingwhen temperatures drop to 37 F (3 C) or below. Whentemperatures rise above this temperature, the sensorwill enable automatic watering.5

To attach the receiver to this type of controller,attach the blue and orange wires to the sensor input.Controllers with 24 VAC Solenoids and a BoosterPump1.

Mounting the ReceiverStandard MountingGutter Mounting (Optional)Using 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 sensor gutter mount can be purchased as an optionalaccessory for your Wireless Rain-Clik (order p/n SGM).The SGM allows the transmitter to be mounted directly tothe edge of a gutter. Install the SGM on the transmitterby removing the metal extension arm supplied with yoursensor and reinstalling the SGM. Position the gutter mounton the edge of the gutter and twist the thumbscrew tosecure it in place.SGMStandard MountGutter Mount11

Adjustments and OperationHints for Mounting the TransmitterReceiver 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' (275 m).The receiver has two LED lights that indicate the state ofthe 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-Clik model 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.Transmitter OperationThere is nothing to set up with the Wireless Rain-Clik.121.

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 enabledFLASHING RED – Indicates that communicationbetween the transmitter and receiver was lostNote:When you first apply power to the receiver,the SENSOR STATUS LED will be RED. Pressthe manual test spindle on the transmitterfor five seconds and release the spindle. TheSENSOR STATUS LED will turn GREEN indicatingproper operation.

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.Note:Units 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.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.LED light13
