Wireless Rain Clik - FAQs

If your wireless sensor is not shutting down irrigation when it rains or if the Sensor Status LED on the receiver continues to be red after the sensor dries out, it is possible that there is no communication between the receiver and the transmitter either because the battery is dead or because there is interference between the two components. Upon verifying that the battery is good, you will need to re-establish communication between the two, and this video will show you how.

Thanks, the last part on matching frequency worked perfectly. My previous Hunter was in place for 10 years when the battery gave out. I bought the new rain sensor and got the red light. It didn't go out after an hour. Following the directions explained in the video I got the new sensor to talk to the old controller.

Solid video, very clear and understood. Anyone on youtube should watch your video before they attempt to make one. Thank you!

Great video; learned exactly what I needed.

Good explanation of the "matched part" transmitter, too bad the battery is sealed and sometimes only lasts 3-4 years, requiring a sevice call and a total replacement of the transmitter ($130.)

I have an hunter X-Core. I have two stations. 1 and 2. Station 1 didn’t not come on but in the panel it showed it was running. But there was no water coming from the drip to the plants. What is the problem? The number 2 station has no problem.

Im having the transmitter issues(last issue you explained). However i dont know where the previous owners placed the transmitter. What can i do?

[@rasheedrk]

My Hunter rain sensor will not flash off on my controller even when I hold it down and heard the click. I also whet on the controller and jump the two sensor wire and will not flash off.

Where can I purchase a replacement rain sensor unit (Hunter WRC) ? Mine has stopped working (battery died). Don't know if I can change the battery though... Thanks! :)

Does anyone know how much rain is needed to activate the wireless sensor? I have had over an inch of rain and the sensor has not activated (shut off the system).

[@dennisdamico5070]

The sensor eventually shut the system off when we received 1.20" inches of rain as measured on my digital rain gage. So it appears the switch is communicating properly. The sensor is located about ten feet away in an open area that does not obstruct free falling rain. It just may be defective?

[@gojones229]

Hey Dennis, my technician failed to remove the chrome jumper connecting sensor 1 and 2. Just pull that out and system should shut off when raining.

[@alanspinner8400]

my sprinkler system will not turn on and my wife says the sensor is on bypass....nothing she has tried seems to work and allow the system to water., HELP

[@billw24]

Is there a way to change the battery on the transmitter?

[@Episcleritis]

Nope. Have to send it in for warranty coverage.

[@thomasbondi3200]

When my receiver is in active mode the screen always reads OFF. I have to run it in bypass for it to work. Any ideas?

Thank you for contacting Hunter Technical Support
If your rain sensor is not shutting off the system, it could be a couple of reasons it is not performing this feature. If you were not able to fix it after going through the steps please reply to the outcome of each step.
• Make sure the terminal jumper has been removed. Most irrigation controllers use a sensor circuit that provides terminals where the sensor wires will connect. If the controller uses a normally closed sensor circuit (most common) the terminals will be connected by a jumper clip or wire. This terminal jumper will need to be removed for the rain sensor to operate correctly.
• Controllers come with a Rain Sensor Bypass switch. Make sure the switch is in the “Active” or “On” position.
• The Mini-Clik sensor can be adjusted to activate at different amounts of rainfall. Check the sensor to see if it is set for the appropriate rainfall amount.
• Make sure the sensor is located in an area where it is unobstructed from the rain. Overhangs, trees, or anything else that may prevent rain from reaching the sensor should be avoided.
• Wiring shorts on the sensor circuit will not allow the controller to recognize an open circuit when the sensor activates. For example, if the sensor wire were stapled to the siding of the house, a staple could cut into the wire insulation and create a short across the two conductors.
