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.

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?
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.
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.
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 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.
Do I need to replace the entire rain sensing unit or can I just replace the transmitter?
Sorry I could not be more helpful!
