Hunter WRF-CLIK Wireless Sprinkler Rain Freeze Sensor

Most rain-sensing devices work by accumulating a set amount of rainfall before a switch is activated that interrupts the circuit from the controller and shuts off the system. In that accumulation time, the system will unnecessarily continue to water. This can look especially bad for conservation-conscious municipalities, businesses, and residences. With built-in Quick Response technology, the Hunter Rain-Clik and Wireless Rain-Clik can command a controller to shut off right when it starts to rain. The Rain-Clik can be mounted on an eave or any flat vertical surface like a wall or fence. A gutter mount is also available that allows for easy installation of the Rain-Clik on the edge of a gutter.

Easy to install and configure
This wireless rain sensor is super easy to install. The receiver wiring to the controller is very easy to complete. Overall a very worthwhile product that allows you to prevent your sprinklers from running while it is raining, or has very recently rained. This is the second one I have installed (the first one was at our previous home) and I have not had any issues with either one. If you have a Hunter sprinkler controller you need this accessory it is worth every penny!

A Must For Water Conservation
I have been using this product for years on many of my accounts. Easy to install and very dependable. It is a must where water is scarce. Management of the irrigation system through water savings helps recoup the costs of the system itself.

Easy to install and pair
It was easy to install and pair with receiver. Works flawlessly. Note for those replacing an old sensor: the new models with the hard plastic antenna will not pair with the old receivers that have the wire antenna. This important piece of info was difficult to find so this may save you the trail and error headache.

J O on Mar 2, 2019
I was looking for a wireless sensor so I didn't need to pick up a new spool of wire and run it through walls and such. Between the cost of the wire and the frustration, the extra cost of the wireless sensor is totally worth it.

Hi, rain sensor not working.

config: a unit next to sprinkler control panel is a Hunter 3' x 3' plastic box with two lights in the middle. one light is sensor bypass and other is sensor status

another wireless unit outside to sense rain. it looks similar to one component included in the picture..

is this s replacement for both units? can i use the outside rain sensor with the existing unit next to controller?

thanks
dave d on May 25, 2012
BEST ANSWER: The Hunter wireless rain sensor system consists of two modules: the receiver consisting of a 3" x 3" plastic box with two lights in the middle and a 5 wire cable, and the wireless rain sensor. The receiver is mounted next to the sprinkler control unit and the rain sensor can be mounted up to 800 feet from the receiver according to the rain sensor specifications. The rain sensor instruction booklet provides step by step wiring and configuration instructions and should be reviewed before proceeding to connect the Receiver to the sprinkler control unit. Also, it is imperative to follow the step-by-step procedure for establishing communication between the sensor and the receiver. If the steps are not followed as explained, receiver and rain sensor will not communicate.

The Receiver wiring is the worst part of the process and must done carefully. Again, follow instructions. The 2 Yellow wires in the 5 wire cable connect inside the sprinkler control unit to the AC1 and AC2 terminals (doesn't matter which goes to which). Two of the other 3 wires, White, Blue and Orange, connect to the SENSOR terminals located adjacent to the AC1 and AC2 terminals. If the SENSOR terminals have a shorting bar across them (bare metal tab connected across each SENSOR terminal), then remove the shorting bar and connect the White wire to one SENSOR terminal and the Blue wire to the other SENSOR terminal (again, doesn't matter which goes to which). This wiring configuring establishes a Normally Closed sensor configuration. The Orange wire is not used as it is for systems using a Normally Open sensor configuration.

The most critical part of the whole process is making the rain sensor "talk" to the receiver. It is a very simple procedure and must be done as the instructions specify or the system will not activate.
Does it work?
Diane A on Jun 1, 2013
BEST ANSWER: YES IT DOES WORK. RAIN SENSORS ARE NOW REQUIRED BY OUR LOCAL MUNICIPAL GOVERNMENT TO STOP UNNECESSARY WATERING OF LANDSCAPES.

THE GAUGE CAN BE ADJUSTED TO ALLOW MORE OR LESS DRYING TIME OF THE CONTACTS THAT ACTIVATE THE SENSOR. FREEZE SENSORS ACTIVATE JUST PRIOR TO FREEZING AS WELL. WITH THE USE OF THE RAINBIRD CONTROLLER BOX YOU CAN BYPASS THE SENSOR IF YOU DO WANT TO WATER PRIOR TO THE CONTACTS DRYING THEMSELVES TO PERFORM A NORMAL IRRIGATION CYCLE.

I WOULD HIGHLY RECOMMEND THIS SENSOR FOR ANYONE NEEDING TO CURTAIL LANDSCAPE WATERINGS DURING RAIN PERIODS.
what is different wrf and wr ?
A shopper on Jan 28, 2019
BEST ANSWER: WR-CLIK is a wireless rain seensor

WRF-CLIK is a wireless rain and freeze sensor.

4. Two models available: Wireless Rain-Clik (WR-CLIK) – 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.
5. Wireless Rain/Freeze-Clik (WRF-CLIK) – The Wireless Rain/Freeze-Clik includes a freeze sensor that is designed to keep the irrigation system from operating when temperatures drop to 37 ̊F (3 ̊C) or below. When temperatures rise above this temperature, the sensor will enable automatic watering
I have an existing wireless Hunter wireless sensor and I need to replace the outside component. Do I need to get a new receiver also?
Jeff G on May 26, 2014
BEST ANSWER: My outside transmitter went south and I replaced both transmitter and receiver last year. The receiver looked OK, and although I was 99% sure that it was the unreplaceble battery that expired on the transmitter I changed both out. I figured a $70 expense on a 10 year old system was a pretty good return on my investment. I guess you can try to replace only the transmitter -- kind of like putting a new engine in with an old transmission in a car. I know this doesn't exactly match your question -- its just the way I thought about it. Good luck. Hope your decision works out.
i am looking to install a PC 400I controller to replace an old richdel unit Looking to add a Hunter solar rain/freeze unit. that is wifi Is this the unit I would use? thanks
william f on Jan 6, 2019
BEST ANSWER: The wireless rain freeze sensor will work with this controller. As far as I know there is not a solar powered or WiFi capable rain/freeze sensor. This one has an internal battery on the unit and it connects wirelessly to the added module which is powered by the controller. Battery last aprx ten years. An HC, pro-hc or hcc controller would give you WiFi capability to control the controller from phone or computer.
can I buy the outside unit only?
A shopper on May 10, 2015
BEST ANSWER: I think you must buy both parts as a set. If the one you have is malfunctioning I would recommend trying to reset it and re sync it first. If this does not solve the issue then check the receiver by your controller for the manufacture date. If it is less then 5 years old it should be covered by Hunter Industries outstanding warranty. Hope this helps.
Does this device work well, how far from control box can it broadcast and do batteries last well in foul weather?
Ron C on Jul 31, 2013
BEST ANSWER: Hi,
I have my rain sensor roughly 150ft away from my timer box which is located in my garage. I have the sensor mounted on my shed in the back yard. I never have any issues with connectivity between transmitter and receiver. The set up works really well for me and kicks in nicely when we get hit with significant rainfall. I have only had this sensor for about a month now so I really can't comment on battery life. Hope it lasts because the battery cannot be changed as the unit is sealed. So far so good.
Hope this helps you with your decision.
My transmitter has stopped transmitting - appears that the battery is dead though we have anly had it for 5 years. The manual says that I can just replace the transmitter but some of the comments in the Q&A seem to indicate that I need the receiver as well as the transmitter. The manual says that I only need to replace the transmitter. Which is it?
Hugh M on Jun 2, 2012
BEST ANSWER: Considering the near-insignificant cost savings and hassle, just buy a new transmitter and receiver kit. That way both parts will be new, and if you really want to save your old one, you will have a back-up receiver.
Does it work with Hunter control panel Hunter SRC?
A shopper on Aug 10, 2018
BEST ANSWER: Yes it should. The sensor comes as an external attachment to the controller that hard wires to the controller. It’s a two part system. Brain for the sensor and actual sensor.
I had an irrigation system installed in 2008. It has a hunter wireless rain sensor. it appears that the battery in the transmitter has expired. Will a newer Hunter sensor work with the older receiver? The older receiver has 4 wires attached to the Rain Bird controller. It has 2 yellow, 1 white and 1 blue wires attached to the controller.
Do I need to replace the entire rain sensing unit or can I just replace the transmitter?
Thank You
William F on Mar 22, 2014
BEST ANSWER: I am not aware of anywhere that you can buy just the outdoor transmitter, however it is possible to just change the transmitter and leave the old receiver connected. You will have to go through the power down receiver and power up / sync the new transmitter procedure so that they will communicate properly. All covered in detail in the manual you will receive with the rain sensor.
Can we get the Rain Clik without the module? We already have the module but our Rain Clik is not working.
A shopper on Apr 9, 2013
BEST ANSWER: THE SENSOR IS SEPERATE FROM THE BASE UNIT THAT IS WIRED TO YOUR CONTROLLER BOX. WHEN YOU GET A NEW SENSOR YOU NEED TO PROGRAM IT SO THE BASE UNIT AND NEW SENSOR CAN "TALK" TOGETHER - JUST LIKE A GARAGE DOOR OPENER. THE BATTERY LIFE IN THE SENSOR ONLY LAST APX 5 YEARS SO REPLACING THE SENSOR AND HAVING THE BASE UNIT RELEARN THE NEW SENSOR COMMANDS IS A NO BRAINER.
system will not shut off during rain?
A shopper on May 1, 2012
BEST ANSWER: I'm not sure I understand the question. If the question is whether the WRF-CLK rain sensor shuts off the sprinkler system during the rain, the answer is yes. It shuts off the system during rain and during freezing conditions. I have used the Hunter sensor for several years. I replaced it about 6 months ago when the battery from the previous sensor ran out.
what is the difference between wr and wrf-clik?
jim g on Mar 30, 2012
BEST ANSWER: Not 100% sure but my guess is that the wrf would have a freeze sensor in it to prevent watering during cold temps. I have not used this particular model because most systems around here are winterized before freezing temps occur. Wireless rain sensor works very well, I highly recommend it. Hope this helps.
Will the Hunter WRF-CLIK wireless rain sensor work with a Rain Bird ESP-RZX controller?
A shopper on May 19, 2014
BEST ANSWER: If the controlller has a rain sensor input or sensor terminals in the terminal block then it should work. Hope this helped you.
Could this product be destroyed by a frog coming in contact with the interior connections?
A shopper on Jan 24, 2013
BEST ANSWER: No way, if the unit is not working it probably due to some else, disconnect and reinstall again as if you were just installing.
I purchased the hunter wireless rain clik sensor a few years ago. It still works but the corks material no longer seems to expand when wet. Is there a cork replacement kit or do I need a new sensor?
James F on Jun 11, 2016
BEST ANSWER: A quick search on Hunter's support website does not show the cork material as a separate item for purchase. It appears as though the only replacement component available is the wireless transmitter, which includes a new battery. If the sensor still works I would keep it in service until it stops doing so. Otherwise you will have to purchase a new sensor if you are wanting to replace the cork material.
Will this rain sensor work with an Orbit Timer?
Steve R on Sep 23, 2012
BEST ANSWER: My guess would be yes, since all the sensing is done by the device.
Hi, I purchased this product through you last June and the battery is already dead. No Light comes on on the unit when the reset is pressed. The manual states that the battery life should last 10 years. Tried to look for the battery to replace it but it seems to be sealed. Please advise?
A shopper on May 9, 2012
BEST ANSWER: Hi, Im not exactly sure what the problem is but I have had my Hunter WRF-Clik installed for the past 8 months and it has worked perfectly since then. I was just looking at the manual online and it appears that you are supposed to hold down the manual spindle button on top of the unit to check the status of the battery. According to your question it looks like you held down the "reset" button instead. Im not sure if we are talking about the same button or not but I would be very interested to hear what the problem ends up being with unit.

Sorry I could not be more helpful!
does this work on a pro c400i controller?
A shopper on May 31, 2016
BEST ANSWER: Yes; my rain sensor is connected to a Hunter Pro C 400i controller.
Does it work with Rachio controllers?
Lawrence H on Apr 4, 2018
Can I purchase only the transmitter for the Hunter wireless rain sensor? If so, what is the part number to view on and order from your website?

I am ordering the Hunter PCC600 outdoor control. If I order this rain sensor is there anything else I need to order or will they communicate?
A shopper on Jun 5, 2013
I have a outdoor Hunter Pro C controller installed in the middle of a landscape berm. I want to Install a WRF-CLIK Wireless Sprinkler Rain Sensor. Is the receiver on this package waterproof and able to be installed next to the outdoor controller in an outside location like this. I intend to install the sensor on building rain gutter nearby?
Doug K on Aug 25, 2013
BEST ANSWER: Have one of these sensors for about a year now. I installed my receiver in my garage when weather is not a factor. The receiver has a weather proof cover over the front of it and I would say that it can definitely resist the weather but I am not sure it is water proof (hard rain). You might check the online manual to see if it recommends any installation locations (or restricts any).
