Rain Bird WR2-RFC Wireless Rain/Freeze Sensor and Timer Interface
- Sensor interface and controller interface (rain AND freeze sensor)
- Compatible with nearly all 24 VAC controllers
- Improves system performance
- Perfect for water conservation
Features & Benefits
Rain and rain/freeze sensors are becoming "must-have" components for irrigation systems these days. Rain Bird designed the new WR2 wireless sensor to exceed the standard. With revolutionary features, this sensor saves time, improves system performance and enhances your reputation as a water management expert.
Reliable signal transmission and other innovations deliver superior responsiveness to rainfall and cold temperatures, while user-friendly features cut installation and programming time in half. Choose your own rainfall set points and save up to 35% on water usage while promoting lush, beautiful landscapes.
Installs faster with one-person
Rain Bird designed the WR2 so that one person can install it quickly and easily. Signal strength is displayed on both the sensor unit and the controller interface. The sensor's innovative versatile mounting bracket quickly attaches securely to a gutter or any vertical surface, such as a fence or wall.
Easier to use and program
Programming the WR2 is simplified for fast set-up. In just a few seconds, you can select set points, program the irrigation modes and save your default. On the controller interface, all settings are displayed on the easy-to-read LCD screen, so you can see signal strength, rain and temperature set points, battery life and more at a glance. Unlike other rain sensors, the WR2 has a long-lasting battery that's quick and easy to replace.
Superior signal reliability
Signal strength is displayed on the controller interface using familiar cell phone icons. Dual antennas safeguard the system from signal interference by radios, mobile phones, power lines, etc. The WR2 system overcomes most line-of-sight obstructions so you have freedom in locating the sensor. Weather data is updated every 45 seconds to ensure the most reliable communication between sensor and controller.

My controller had a separate connection for the sensor input. It basically serves as a on/off override switch. It gets its signal from the rain gauge controller. The wire that leads out from the sensor, if you connect it to 2 or more wires, then run those individual wires to each separate controller, in theory should work.
The Controller Interface unit appears well sealed and suitable for indoor or outdoor installation.
There is no reference in the installation manual to define where (indoor or outdoor) it should be installed.
To be certain, and to ensure the terms of the warranty are not violated, it would be best to get a definitive answer from Rain Bird.
If there isn't a hookup for a rain sensor, there is an alternate hookup method that is just slightly more complicated. In that configuration, all the valve power runs through the interface module and, when rain is sensed, power is cut so the valves won't open.
I can't imagine a scenario that won't work but check the manual. It has all the relevant info you'll need.
I´d like to know Rain Bird WR2-RFC is suitable with controller EC 4?
Electrical rating suitable for use with up to six 24VAC 7VA solenoids plus an additional master valve or pump start that does not exceed 53VA
Does this mean I cannot use it if I have ten zones?
I'd check the products manual to see if you can find this in there.
