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.

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
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.
Hope this helps.
Thanks in advance!
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.
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.
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.
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
