Hunter RainClik Rain 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.

Don't install a system without a rain sensor
I am shocked at the number of systems, especially commercial system that don't have rain sensors. It is pouring down rain and their system is running, silly.

Great response and reliability
Using this product on all four of our Hunter controllers on two properties. Never fails to shut off quickly and restores service nicely. Easy install on fence, eaves, or patio structure nearby. One we had to extend about 50 feet, but no problems at all; just used bell wire from local hardware store. Ordering three more for another property (rental)-- one less thing to think about with renters!

Hunter Rain Sensor
This is my second one. The first one worked fine for a few years then the moisture sensing disks get a algae type growth in them and stop expanding/working. Failed in the closed position so irrigation did continue to water even if it rained. Don't know if a yearly chlorine spray treatment will prevent this but might extend its working life. Plan to try it on the new one I just installed. I know, just voided my warranty. ha ha.
All other materials held up fine without corrosion or problems. Mounting and installing was easy. Bought the same model because I believe it to be pretty good and don't think any other design would fare any better. So, what is the price of the water you save over 3 years compared to the price of the sensor? Don't think it matters as its really about saving fresh water. Hope this helped.

Cord too short
The sensor was sent with 25 foot of electric wiring. My unit is 40 feet from the sprinkler system controller box. I had to splice a portion of the new wiring to the old wiring. Hopefully, it will work.

does it come with a mounting bracket ?
A shopper on Mar 12, 2012
BEST ANSWER: Yes it does. It comes with all necessary mounting hardware for multiple locations and positions. It also includes a complete instruction guide.
Will this fit a hunter pro C ?

Is this the wireless outside sensor?
Walter J on Mar 13, 2015
BEST ANSWER: Not wireless. Wireless looks similar but has a little wire(antenna). Also need the receiver part that attaches to controller.
Is this sensor wireless?
A shopper on Nov 8, 2011
BEST ANSWER: No, this sensor is not wireless. It hooks into your control unit with two wires. If you have your owners manual, it will show you which two terminals to hook the sensor onto. Be sure to remove the jumper from these two terminals (if there is one), or the sensor will not be able to control your unit.
Is it easy to install?
Irv B on Sep 22, 2011
BEST ANSWER: You'll need to find a place within reach of the wire provided (or add a longer wire yourself) to attach it to the roof. I screwed mine in right above the gutter and ran the wire thru the attic to the contol box. Two wires to connect and it works like a charm!
Is this sensor wireless ?
Thomas P on Jun 22, 2011
BEST ANSWER: The sensor on this page is not a wireless unit, it comes with an attached 2-wire cable which must be connected to your sprinkler control system (timer). There is a wireless version of this unit available, probably at a higher cost. I am not familiar with that unit, but this wired unit performs perfectly compared to the cheap tray-style sensor my installer used. I'm sure the wireless unit is identical in terms of operation, and it would enable you to use it on your system, even if you cannot run wires from the unit to your controller. If you need further info on these products, there are usually links on the product pages which can give you further information about each product.
Does this rain delay sensor fail after some period of use?
A shopper on Jun 2, 2014
BEST ANSWER: all sensors fail after a while.
These are exposed to the elements all year around, rain/snow/ice/sun cycles. Sometime, the wires inside get corroded or the level or the plunger that pushes down on the on/off switch gets dirt on it and sticks.

if you are handy, take them apart and you can rebuild it. There is no magic in these sensors. a switch that gets pushed when the rain soaked disks get heavier and push the plunger down, as they dry they rise up
How much wire comes with the RainClik Sensor?
JJ D on Jun 1, 2017
BEST ANSWER: A lot. At least 25 feet. You can also just add more wire to it. Just make sure you cap and tape connection. I run 80 feet and it works fine
Will I need to do any kind of reprogramming?Or,will the new one work right out of the box.
A shopper on Jul 8, 2015
BEST ANSWER: This unit works right out of the box depending on what you has there before. If you have a complex timer with wireless rain, freeze sensor, then you will have to install this differently than the wireless unit. If you have another unit like this one, you either install it between the common wire on the timer or into the "sensor" port on the timer. I have found that it is easier to install this between the common wire. Very simple installation.
When the by-pass is activated,the by-pass led will be red and the status led will remain red until the disks dry out, right? but thereafter will the sensor re-enable itself?
A shopper on Aug 19, 2014
BEST ANSWER: On a Hunter controller, when the switch is set to "Bypass" it ignores the rain sensor and will operate at the pre programmed times regardless of rain fall. When set to "Active" the valves will not activate when the sensor has collected enough rain. When the disks dry out, the valves will again operate as programmed. You can control the time it takes for the disks to dry out with the adjustment on the top.
Does this unit come with the mounting bracket? (not gutter mount)
A shopper on Aug 28, 2011
BEST ANSWER: Yes. The mini-click comes with a bracket and 2 screws. I mounted it to a tall post at a right-angle. Just be sure you wire it to the controller correctly, or your sprinklers will continue to run in the rain!
On the hunter system,I want to install a wired system. But I need closer To 40 ft of wire instead of the 25' that comes with the unit. Are there any solutions?
Frank P on May 6, 2017
BEST ANSWER: I had the same issue. On one system, which needed extra wire inside the garage, i just used bell wire. On another system, i used some 3-wire sprinkler valve wire. Of course you only need two of those wires for the sensor.. With the small gauge wire on the sensor, i found 3M telco wire connectors worked great and they're waterproof, too..
How to tell if rain sensor is normally open or closed?
A shopper on Jun 9, 2016
BEST ANSWER: Just look at the grill (5 openings) on the side of the unit. If each opening is unobstructed then it is fully open. If each is fully obstructed, then it is fully closed. Any result in between allows for various rates of evaporation, which in turn affects how much time will pass before the timing function is again operable. Adjust the grill by turning the top of the unit where rain enters.
What is the difference between the Hunter RainClik Rain Sensor and the Hunter MiniClik Sensor?
A shopper on Feb 3, 2014
BEST ANSWER: Hi - the miniclik sensor has only one adjustable rain sensing switch that shuts off your system after it rains enough to expand the internal absorbent disks that trigger the switch. Once these disks dry out which can take some time after a heavy/long rain, then the switch shuts off and allows your system to run.

The rainclik sensor has 2 switches. The first one is the same as the miniclik. Then there is an additional 2nd switch which detects if it starts to rain and triggers the switch to shut off your system right away. It triggers much faster than the first switch so that you are not watering in the rain. If it rains heavy and long enough, the first switch will also trigger which takes much longer to dry out and will keep your system from turning on until that happens.
can you purchase just the rain sensor w/o the receiver ?
John ` L on Jun 27, 2018
BEST ANSWER: I originally purchased the Hunter Pro-C controller with the SolarSync option. The SolarSync option quit working. Reset didn't help. Unit was about 5 years old. I wasn't crazy about the SolarSync option. I think it was an overkill for what I needed. With the help of Tech Support at Sprinkler Warehouse, I replaced the entire SolarSync option (receiver and sensor) with the RainClik sensor. Works great!
Hope this helps.
can i purchase just the wireless hunter rain clik sensor or do I have to buy the receiver also?
Barry on May 26, 2017
BEST ANSWER: You can buy them separately but I bought the both of them.Made an error on previous answer sorry for that.If you already have the receiver your good to go!
I have an older rain gauge, it has OCT 07 stamped on the side, and I'm pretty sure the battery is dead. Is there a replacement I can get for just the transmitter? I've read in a few places that "replacement" rain gauges don't work with sensors made before 2011.

Thanks in advance!

Jason
A shopper on Jun 3, 2014
BEST ANSWER: Jason,
This is the wired version of the sensor, I'm guessing you want a wireless one. I purchased this last year also thinking it was the wireless model. It may or may not work, depending on whether your controller had the terminals for the wires.
My rain sensor battery is dead, I know we can not change the battery, but can I just buy the sensor and not the base as the base unit is still working with all the lights on. If I can buy only sensor how does it program with the old base ?
Thanks
Sam
Sam S on Sep 24, 2013
BEST ANSWER: From your description I assume your are talking about a wireless RainClick, if so then Yes, You can get the sensor only. However it is sometimes hard to find a supplier that has the sensor only. On a side note the unit has a five year warranty. Look on the bottom of the sensor it should have a date. If that date is less than five years old you should be able to get it replace under warranty.
Will this sensor work with a 9V DC controler?
Bruce P on Aug 13, 2012
BEST ANSWER: I'm not an electrician, but I found the instructions easy to follow. On my control system, I simply connected the sensor wires into the common wire going to my solenoids. When there is enough rain, the sensor acts as a circuit cutting switch, interrupting the common wire continuity. So, the controller works on schedule, but the solenoids do not function because the circuit has been interrupted. Later, when the sensor dries out, the circuit is closed, and the controller operated the solenoids on the schedule you set. You can find pdf installation instructions on the Sprinkler Warehouse website for the sensor. They should give you all the info you need. They did for me.

Charlie P
Explain the function of this product, and where does it attach to the system?
A shopper on Mar 27, 2012
BEST ANSWER: The function of the rain sensor is to interrupt the activation of your irrigation system during and immediately following rainfall. This saves money (cost of water) and energy. You can adjust the RainClik sensor to either lengthen or shorten the shut off time after the rainfall.

It attaches to the system in the control box. pull the cover plate to expose the wiring. You should find 2 screw heads, side by side, that have a jumper between them. Simply remove the jumper and attach one of each of the wires from the sensor to each of the screw heads.
Does it work similar to the rain bird model where when the cork inside the sensor gets wet it swells to break the connection? Or is this a water sensor? If so does it "disconnect" when the sensor dries?
Rick D on Mar 8, 2012
BEST ANSWER: I don't know the answer, sorry. I own it and have it tied into 4 Hunter controllers. It works great. I would be surprised about a cork componenent, it looks all electronic so water sensor is my guess. The Rainbird wouldn't work on the hunters controller, i think Hunter is always open.
Do you have the "Normally-Open" version of this sensor available?
Eric C on Sep 8, 2011
BEST ANSWER: Actually, on the page, the sensor says: Wiring: normally closed or normally open . I wonder if Hunter updated the product and put a dipswitch or a 3rd wire to make the device either NC or NO.
Can I use this sensor? I have wireless system and I need a wireless sensor.
Thomas P on Jun 24, 2011
BEST ANSWER: You still need to wire the wireless receiver to your controller. Install the sensor outside to control when the sprinkler system will run.
i need a rain clik sensor unit that mounts remote on a fence ,not the receiver unit, that unit works ok
A shopper on Apr 8, 2011
BEST ANSWER: I purchased a RainClik sensor, and have it mounted on a fence behind my garage. It is connected by underground rated wires to a Hunter controller that is mounted inside of my garage. I've had no problems with this setup. The RainClik works perfectly well
Does this work with the Hunter Pro-C?
Sandy G on Aug 2, 2018
BEST ANSWER: I would think so, I have an older Hunter controller and it works as advertised.
when the plunger is depressed manually, should the contacts be open or closed?
Dwight H on Jun 15, 2017
BEST ANSWER: Contacts should close when water expands media and activates plunger
Will this work with Hunter 800 I control unit?
Virendra P on Jun 3, 2016
BEST ANSWER: Am not sure, but I would imagine it's compatible with any Hunter controller.
My transmitter died. Do I need to purchase a new receiver as well?
A shopper on May 25, 2016
BEST ANSWER: I purchased the RainClik Sensor to solve my problem. My system was not turning off during rain. By installing a new sensor it corrected it for me.
Is it compatible with Rain Bird ESP-8 Controller?
steven j on May 15, 2016
BEST ANSWER: You can use the normally closed feature of the Rain Sensor by connecting inline with the Common of all valves.

The Yellow wires connect to the AC 24V supply in the controller.
The Blue and White wires would be used so that the Blue wire connects to the Common going to all the valves and the White wire goes to the C (Common) terminal in the Controller (Normally Closed contacts). This should interrupt the Common connection to the valves whenever the Sensor is triggered keeping them from coming on.
What determines which sensor I have to use, I have been told that certain timers need a "normally open" or a "normally closed" rain sensor, why?
Maria N on Dec 11, 2015
BEST ANSWER: Normally closed means the sensor passes current (a complete circuit) when it is dry and breaks the current path when it gets wet. If you have an input for a rain sensor input specified as normally open on your timer this is the right thing to buy. If you don't have a rain sensor input, this ones comes with instructions on how to install. Unlike this one, a normally open sensor doesn't pass current until is gets wet.

In a light rain this sensor detects the rain quickly after the rain stops. If dry weather follows the rain the sensor will close and allow your spirnklers to operate. In a heavy rain the sensor will remain wet and hold your sprinklers off for several hours to several days. Air flow and heat cause the sensor to dry out. There is an air flow adjustment to control how fast the sensor will dry out.

It works perfectly for me. Recommended
